Vulnerability Details

CVE-ID: CVE-2025-53766

Affected Software: Unknown Multiple Products

Affected Versions: See vendor advisory for specific affected versions

Vulnerability: This vulnerability is a heap-based buffer overflow within the Windows Graphics Device Interface (GDI+) library. A heap-based buffer overflow occurs when a program writes data past the end of an allocated memory buffer on the heap. An attacker can exploit this by crafting a malicious image file or other graphical data. When a vulnerable application uses the GDI+ library to process this malicious file (e.g., rendering an image in a web browser, email client, or document), the overflow is triggered. This can corrupt memory in a way that allows the attacker to hijack the application's control flow and execute arbitrary code on the target system with the same permissions as the user running the application.

Business Impact

This vulnerability is rated as critical severity with a CVSS score of 9.8. Successful exploitation grants an attacker the ability to execute code remotely, leading to a complete compromise of the affected workstation or server. The potential business impact is severe and includes the theft of sensitive corporate data, customer information, or intellectual property; installation of malware such as ransomware, leading to operational downtime and financial loss; and using the compromised system as a foothold to launch further attacks against the internal network. The reputational damage resulting from a breach of this nature could also be significant.

Remediation Plan

Immediate Action: Identify all systems and applications that utilize the Windows GDI+ component and apply the necessary security updates provided by the relevant software vendors as soon as they become available. Patching of internet-facing systems (e.g., web servers, email gateways) and critical assets should be prioritized. Following patching, monitor for any signs of exploitation attempts and review system and application access logs for anomalous activity.

Proactive Monitoring: Security teams should configure monitoring tools to detect potential exploitation. This includes monitoring for unusual process creation from applications that commonly handle images (e.g., web browsers, email clients, office suites). Scrutinize network traffic for suspicious outbound connections from endpoints, which could indicate a connection to an attacker's command-and-control server. EDR and SIEM solutions should be tuned to detect memory corruption anomalies or specific patterns associated with GDI+ exploits.

Compensating Controls: If patching cannot be immediately deployed, the following compensating controls can help mitigate risk:

• Implement network segmentation to contain any potential breach and prevent lateral movement.
• Use application control or whitelisting solutions to prevent the execution of unauthorized code or malware.

Vulnerability: The vulnerability exists within the jackrabbit-spi-commons and jackrabbit-core components of Apache Jackrabbit versions prior to 2.0. These components improperly parse XML input without disabling external entity resolution. An unauthenticated remote attacker can exploit this by submitting a specially crafted XML payload to an application endpoint that uses the vulnerable library. This payload forces the XML parser to access arbitrary files on the local filesystem or initiate network requests to internal or external systems, a technique known as Server-Side Request Forgery (SSRF). As this is a "Blind" XXE, the attacker does not receive the data in a direct response but can exfiltrate it out-of-band by forcing the server to send the data to an attacker-controlled system.

Business Impact

This vulnerability is rated as High severity with a CVSS score of 8.8. Exploitation poses a significant risk to the confidentiality and integrity of the affected systems and the data they process. Potential consequences include the theft of sensitive configuration files, application source code, user credentials, and private cryptographic keys. Furthermore, the ability to perform SSRF attacks could allow an attacker to pivot from a compromised public-facing server to scan and attack other systems within the internal network, escalating the incident from a single system compromise to a broader network breach.

Remediation Plan

Immediate Action: Apply the security updates provided by the vendor "Blind" immediately across all affected products. Prioritize patching for internet-facing systems to reduce the attack surface. After patching, continue to monitor for any signs of exploitation attempts by reviewing relevant access logs and system activity for anomalies preceding the patch deployment.

Proactive Monitoring: Security teams should actively monitor for indicators of compromise. In web server and application logs, search for requests containing XML data with suspicious structures like <!ENTITY ...> or SYSTEM "file:///...". Monitor outbound network traffic from affected servers for unexpected DNS lookups or HTTP/S connections to unknown external IP addresses, as this is a primary indicator of out-of-band data exfiltration from a Blind XXE attack.

Compensating Controls: If immediate patching is not feasible, the following controls can help mitigate risk:

• Web Application Firewall (WAF): Deploy and configure a WAF with rulesets designed to detect and block common XXE attack patterns in incoming traffic.
• Egress Filtering: Implement strict network egress filtering rules on the host firewall or network perimeter to block all outbound connections from the server, except for those that are explicitly required for business operations. This can prevent data exfiltration.
• Disable DTDs: If possible through application configuration, disable the processing of Document Type Definitions (DTDs) in the application's XML parser to prevent the vulnerability from being triggered.

Exploitation Status

Public Exploit Available: false

Vulnerability Details

CVE-ID: CVE-2025-53578

Affected Software: Improper Multiple Products

Affected Versions: See vendor advisory for specific affected versions

Vulnerability: The vulnerability exists due to an improper control of filenames used in PHP's include or require statements. An attacker can exploit this by crafting a malicious request that manipulates a URL parameter to specify a path to a file on the server's local file system. Because the application fails to properly sanitize this user-supplied input, it includes the specified file for processing. This allows an attacker to read the source code of any file the web server process has access to, including sensitive configuration files containing credentials. In certain configurations, if an attacker can also upload a file or poison a log file with PHP code, this vulnerability can be escalated to achieve Remote Code Execution (RCE).

Business Impact

This vulnerability is rated as High severity with a CVSS score of 8.1. Exploitation could have a significant negative impact on the business. An attacker could leverage this flaw to steal sensitive information, such as customer data, intellectual property, or authentication credentials, leading to major data breaches and regulatory fines. If escalated to remote code execution, an attacker could gain full control of the server, enabling them to install malware, pivot to other internal systems, or disrupt critical business operations, resulting in financial loss and severe reputational damage.

Remediation Plan

Immediate Action: The primary and most effective remediation is to apply the security updates provided by the vendor immediately across all affected assets. After patching, it is critical to monitor for any signs of exploitation attempts by reviewing web server and application access logs for indicators of compromise that may have occurred prior to remediation.

Proactive Monitoring: Security teams should actively monitor web server logs for requests containing directory traversal patterns (e.g., ../, ..%2F) or PHP filter wrappers (e.g., php://filter) in URL parameters. Implement alerts for unusual file access patterns or outbound network connections originating from web servers. System monitoring should also be configured to detect the creation of unexpected files or processes running under the web server's user context.

Compensating Controls: If immediate patching is not feasible, the following compensating controls can help mitigate risk:

• Deploy a Web Application Firewall (WAF) with rules specifically designed to detect and block LFI and directory traversal attack patterns.
• Harden the PHP configuration by ensuring allow_url_include is disabled and restricting the paths PHP can access with the open_basedir directive.
• Apply the principle of least privilege by ensuring the web server process runs with minimal permissions necessary and cannot read sensitive files outside of the web root directory.

Exploitation Status

Public Exploit Available: false

Analyst Notes: As of August 28, 2025, there are no known public exploits or active exploitation campaigns targeting this vulnerability. However, Local File Inclusion vulnerabilities are well understood and straightforward to exploit.
