Monitor server performance metrics (CPU utilization, memory usage, disk I/O) for sudden and sustained spikes that could indicate an ongoing DoS attack.

Compensating Controls: If immediate patching is not feasible, implement a Web Application Firewall (WAF) or a reverse proxy to enforce rate limiting on the /Home/UploadStreamDocument endpoint. Configure rules to temporarily block IP addresses that exceed a reasonable request threshold within a given timeframe.

Exploitation Status

Public Exploit Available: false

Analyst Notes: As of October 20, 2025, there are no known public exploits or active exploitation campaigns targeting this vulnerability. However, due to the straightforward nature of rate-limiting attacks, it is highly probable that proof-of-concept exploits could be developed quickly by threat actors.

Analyst Recommendation

Given the High severity rating and the significant potential for business disruption, it is strongly recommended that the organization prioritize the deployment of the vendor-supplied security patches across all affected SigningHub instances. Although this vulnerability is not currently listed on the CISA KEV (Known Exploited Vulnerabilities) catalog, its impact on service availability warrants immediate attention. If patching is delayed for any reason, the implementation of compensating controls, such as WAF-based rate limiting, should be considered an urgent and critical temporary measure to mitigate risk.

Executive Summary:
A high-severity vulnerability exists within the AMD Graphics Driver that stems from improper input validation. An attacker with local access could exploit this flaw by providing a specially crafted pointer to the driver, which could lead to a system crash or allow the attacker to write arbitrary data to memory, potentially resulting in a full system compromise.

Vulnerability Details

CVE-ID: CVE-2024-36352

Affected Software: AMD Multiple Products

Affected Versions: See vendor advisory for specific affected versions

Vulnerability: The vulnerability is an improper input validation flaw within the AMD Graphics Driver. The driver, which operates at a high privilege level (kernel mode), fails to properly sanitize or validate pointer values supplied by a lower-privileged user-mode application. An attacker can exploit this by crafting a malicious application that passes a specific, invalid pointer to the driver, leading to a memory corruption condition known as an arbitrary write. This allows the attacker to write controlled data to an arbitrary location in kernel memory, which can be leveraged to execute code with system-level privileges or cause a system crash (Denial of Service).

Business Impact

This vulnerability presents a significant risk to the organization, classified as High severity with a CVSS score of 8.4. Successful exploitation could lead to two primary outcomes. A denial of service attack would cause critical systems, such as workstations and servers, to crash, leading to operational downtime and loss of productivity. More critically, the arbitrary write capability could allow an attacker who has already gained initial low-privilege access to escalate their privileges to the highest level (SYSTEM/root), completely compromising the affected asset. This could lead to a severe data breach, deployment of ransomware, theft of intellectual property, and circumvention of all security controls on the compromised machine.

Remediation Plan

Immediate Action: Apply the security updates released by AMD to all affected systems immediately. Prioritize patching for critical workstations, servers, and systems used by privileged users. After patching, monitor system event logs for any unexpected crashes or errors related to the graphics driver and review access logs for signs of unauthorized activity.

Proactive Monitoring: Utilize Endpoint Detection and Response (EDR) tools to monitor for anomalous process behavior, especially processes interacting with the AMD graphics driver or attempting memory-writing operations. System administrators should monitor for unexpected system reboots or crashes (e.g., Blue Screen of Death in Windows, Kernel Panics in Linux) which could indicate failed exploitation attempts.

Compensating Controls: If immediate patching is not feasible, implement compensating controls to reduce risk. Enforce the principle of least privilege to ensure users operate without administrative rights, limiting an attacker's ability to run the malicious code required for exploitation. Use application control or whitelisting solutions to prevent the execution of unauthorized software on critical systems.

Exploitation Status

Public Exploit Available: false

Analyst Notes: As of September 7, 2025, there are no known public proof-of-concept exploits or active exploitation campaigns targeting this vulnerability. However, vulnerabilities of this type (kernel-level arbitrary writes) are highly sought after by threat actors for use in privilege escalation chains. The vulnerability is not currently listed in the CISA Known Exploited Vulnerabilities (KEV) catalog.

Analyst Recommendation

Given the high severity (CVSS 8.4) and the potential for complete system compromise via privilege escalation, we strongly recommend that the organization prioritizes the immediate deployment of the vendor-supplied patches. All workstations and servers with AMD graphics components should be identified and patched on an emergency basis. While there is no current evidence of active exploitation, the technical details of the vulnerability make it a prime target for future development of exploits, warranting swift and decisive remediation.

Executive Summary:
A high-severity vulnerability has been identified in AMD RomArmor, a foundational security feature. This flaw allows an attacker to bypass security protections when a system resumes from a standby state, potentially enabling them to steal sensitive data or compromise the system's integrity. Organizations should treat this as a high-priority issue and apply vendor-provided patches immediately to mitigate the risk of system compromise.

Vulnerability Details

CVE-ID: CVE-2024-36326

Affected Software: AMD Multiple Products

Affected Versions: See vendor advisory for specific affected versions

Vulnerability: The vulnerability exists due to a missing authorization check within the AMD RomArmor firmware security feature. RomArmor is designed to ensure the integrity of the system during the boot process. However, this flaw can be exploited during the system resume sequence from a low-power standby state (e.g., S3 sleep). An attacker with prior access to the system could leverage this window to execute code or access memory without proper validation, effectively bypassing the protections RomArmor is intended to provide and compromising the hardware-level root of trust.

Business Impact

This is a High severity vulnerability with a CVSS score of 8.4, posing a significant risk to the organization. Successful exploitation could lead to a complete compromise of the affected endpoint's confidentiality and integrity. The primary business impacts include the potential for data breaches involving sensitive corporate or customer information, loss of system integrity through the installation of persistent malware (rootkits), and reputational damage. A compromise at the firmware level undermines higher-level security controls and can be exceptionally difficult to detect and remediate.

Remediation Plan

Immediate Action: Apply vendor security updates immediately. System administrators must identify all affected assets and deploy the corresponding firmware (BIOS/UEFI) updates provided by AMD and its OEM partners (e.g., Dell, HP, Lenovo). In parallel, security teams should monitor for exploitation attempts and review access logs for any anomalous activity, particularly around system resume events.

Proactive Monitoring: Security teams should configure endpoint detection and response (EDR) tools and system logging to flag unusual activity following a system resume from standby. Specific indicators to monitor include unexpected process execution, unauthorized memory access attempts, or crashes that occur immediately after a system wakes up. Reviewing system event logs for patterns of repeated or failed resume events may also indicate attempted exploitation.

Compensating Controls: If immediate patching is not feasible, organizations should consider disabling the S3 sleep/standby state via system policy as a temporary mitigation. Forcing systems to either fully shut down or use hibernate (S4) instead of standby will prevent the vulnerable resume path from being triggered. Additionally, reinforcing physical security for all assets is crucial, as this type of vulnerability may be leveraged by an attacker with physical access.

Exploitation Status

Public Exploit Available: false

Analyst Notes: As of September 7, 2025, there are no known public proof-of-concept exploits or active attacks targeting this vulnerability in the wild. This vulnerability is not currently listed on the CISA Known Exploited Vulnerabilities (KEV) catalog. However, vulnerabilities in hardware and firmware-level security features are of high interest to sophisticated threat actors, and the public disclosure may accelerate exploit development.

Analyst Recommendation

Given the high severity (CVSS 8.4) and the critical role of RomArmor in platform security, we recommend that all available firmware patches for this vulnerability be applied with urgency. Although there is no current CISA KEV listing or evidence of active exploitation, the potential for a full system compromise makes proactive patching the most effective risk reduction strategy. Organizations should prioritize this update across their entire fleet of affected AMD-based systems and consider implementing compensating controls, such as disabling standby mode, on critical systems where patching may be delayed.

Executive Summary:
A high-severity vulnerability has been identified in AMD StoreMI™ software, which stems from incorrect default security permissions. This flaw could allow a local attacker with basic user access to escalate their privileges, potentially gaining full administrative control of the system and executing arbitrary code. This poses a significant risk to the confidentiality, integrity, and availability of affected systems.

Vulnerability Details

CVE-ID: CVE-2024-21923

Affected Software: AMD Multiple Products

Affected Versions: See vendor advisory for specific affected versions

Vulnerability: The vulnerability exists due to improper default permissions set on files or directories used by the AMD StoreMI™ software during its installation or operation. A low-privileged local user can modify or replace a legitimate application component within the StoreMI program folders with a malicious payload. When a high-privileged process associated with StoreMI attempts to execute this component, the attacker's malicious code is executed with elevated system-level permissions, leading to a full system compromise.

Business Impact

This vulnerability is rated as High severity with a CVSS score of 7.3. Successful exploitation could lead to a complete loss of confidentiality, integrity, and availability on the affected endpoint. An attacker could install persistent malware, exfiltrate sensitive data, deploy ransomware, disrupt critical operations, or use the compromised machine as a pivot point to move laterally across the corporate network. The direct business risks include data breaches, financial loss from operational downtime, and reputational damage.

Remediation Plan

Immediate Action: The primary remediation step is to identify all systems running the vulnerable AMD StoreMI™ software and immediately apply the security patches provided by AMD. As a secondary measure, administrators should manually review the file and directory permissions for the StoreMI installation and ensure they are hardened to prevent modification by non-administrative users, adhering to the principle of least privilege.

Proactive Monitoring: Monitor for any unauthorized or unusual file modifications within the AMD StoreMI™ installation directories. Security teams should configure endpoint detection and response (EDR) systems to alert on suspicious process creation originating from StoreMI services, particularly if those processes are running with elevated privileges (e.g., as SYSTEM). Review system security logs for events indicative of privilege escalation attempts.

Compensating Controls: If immediate patching is not feasible, implement compensating controls. Use application control solutions, such as Windows AppLocker or third-party tools, to prevent the execution of unauthorized executables from the affected AMD directories. Restrict interactive logon access to essential personnel on systems where the vulnerable software is installed to reduce the attack surface.

Exploitation Status

Public Exploit Available: false

Analyst Notes: As of November 23, 2025, there are no known public proof-of-concept exploits or active exploitation campaigns targeting this vulnerability. However, local privilege escalation vulnerabilities are highly sought after by threat actors who have already established an initial foothold in a network, as they are a key component in post-exploitation attack chains.

Analyst Recommendation
Given the high severity (CVSS 7.3) and the potential for complete system compromise, this vulnerability presents a significant risk. Although it is not currently listed on the CISA KEV list and lacks a public exploit, its nature as a local privilege escalation makes it a prime target for post-compromise activities. We strongly recommend that organizations prioritize the identification of all affected assets and deploy the vendor-supplied patches without delay to prevent potential exploitation.

Executive Summary:
A high-severity vulnerability, identified as CVE-2024-21922, exists in AMD StoreMI™ software. This flaw allows a local attacker to elevate their privileges on a system, potentially leading to arbitrary code execution and full system compromise. Organizations using the affected AMD software should prioritize immediate remediation to prevent unauthorized access and control of their systems.

Vulnerability Details

CVE-ID: CVE-2024-21922

Affected Software: AMD StoreMI™

Affected Versions: See vendor advisory for specific affected versions

Vulnerability: This vulnerability is a form of DLL (Dynamic-Link Library) hijacking. The AMD StoreMI™ application attempts to load a DLL without specifying its full, absolute path. An attacker with standard user permissions on the system can place a specially crafted, malicious DLL in a directory that the application searches before the legitimate DLL's location. When the vulnerable AMD software is launched, it will inadvertently load and execute the attacker's malicious code with the elevated privileges of the StoreMI application, leading to privilege escalation.

Business Impact

This vulnerability is rated as high severity with a CVSS score of 7.3. A successful exploit could grant an attacker full administrative or SYSTEM-level control over an affected workstation or server. This level of access could lead to severe business consequences, including the theft of sensitive corporate data, deployment of ransomware, installation of persistent malware for long-term espionage, and disruption of critical business operations. A compromised system could also be used as a pivot point to launch further attacks across the internal network.

Remediation Plan

Immediate Action:

• Identify all assets running the vulnerable versions of AMD StoreMI™ software.
• Apply the security patches provided by AMD immediately, prioritizing critical systems and servers.
• Review user permissions and access controls to enforce the principle of least privilege. This can limit an attacker's ability to place malicious files in sensitive locations on the file system.

Proactive Monitoring:

• Monitor system logs for unusual process creation originating from AMD StoreMI™ executables.
• Utilize endpoint security tools (like Sysmon) to monitor for unexpected DLLs being loaded by the StoreMI process (Event ID 7).
• Watch for suspicious file write operations in the application's directory or other locations within the standard DLL search path.

Compensating Controls:

• If immediate patching is not feasible, implement application whitelisting (e.g., AppLocker, Windows Defender Application Control) to restrict the execution of unauthorized DLLs.
• Harden file system permissions to prevent standard users from writing files to directories where the application resides or in system-wide paths like C:\Windows.
• Ensure Endpoint Detection and Response (EDR) solutions are deployed and configured to detect and block common DLL hijacking techniques.

Exploitation Status

Public Exploit Available: false

Analyst Notes: As of November 23, 2025, there is no known public proof-of-concept exploit or evidence of this vulnerability being actively exploited in the wild. However, DLL hijacking is a well-documented and widely understood attack technique. The barrier to developing a functional exploit is low for a determined attacker who has already established a foothold on a target system.

Analyst Recommendation

Given the high severity rating and the potential for complete system compromise, this vulnerability poses a significant risk. Although CVE-2024-21922 is not currently in the CISA KEV catalog, its nature as a privilege escalation flaw makes it an attractive target for post-exploitation activities. We strongly recommend that all affected systems are patched on a priority basis. Organizations should treat this vulnerability with urgency and adhere to their patching policies for high-risk flaws to mitigate the threat of a local attacker gaining full control of enterprise assets.

Vulnerability Details

CVE-ID: CVE-2021-26383

Affected Software: AMD Multiple Products

Affected Versions: See vendor advisory for specific affected versions

Vulnerability: The vulnerability is an insufficient bounds checking issue within the AMD Trusted Execution Environment (TEE). An attacker with the ability to execute code in userspace can send a command with malformed arguments to the TEE driver. Because the driver fails to properly validate the size of these arguments, it can be forced to write data outside of its intended memory buffer, resulting in an out-of-bounds write. This memory corruption can be leveraged by an attacker to cause a denial of service (system crash) or potentially corrupt sensitive data managed by the TEE, leading to a loss of integrity.

Business Impact

This is a High severity vulnerability with a CVSS score of 7.9. Successful exploitation poses a significant risk to the stability and trustworthiness of affected systems. The primary business impacts include disruption of services due to system crashes (loss of availability) and potential corruption of critical data (loss of integrity). While an attacker needs prior access to the system, this vulnerability provides a pathway for them to escalate their impact, undermine security controls that rely on the TEE, and destabilize critical infrastructure. This could lead to operational downtime, data integrity issues, and a loss of confidence in the security posture of affected assets.

Remediation Plan

Immediate Action: Apply vendor security updates immediately. Organizations should identify all systems with affected AMD processors and deploy the relevant firmware or driver updates provided by AMD and system manufacturers.
