Description
A security vulnerability has been detected in SourceCodester Wedding Reservation Management System 1
Remediation
Apply vendor security updates immediately. Monitor for exploitation attempts and review access logs.
Executive Summary:
A high-severity vulnerability has been identified in the AWS VPN Client for macOS, which could allow a local attacker to gain elevated privileges on an affected system. An attacker with standard user access could exploit this flaw to overwrite critical system files, potentially leading to a full system compromise. Organizations are urged to apply the vendor-provided security updates immediately to mitigate this risk.
Vulnerability Details
CVE-ID: CVE-2025-11462
Affected Software: AWS VPN Client for macOS
Affected Versions: All versions in the 1.x series prior to the patched release. See vendor advisory for specific affected versions.
Vulnerability: The vulnerability, classified as Improper Link Resolution Before File Access (CWE-59), exists in how the AWS VPN Client handles files on macOS. An authenticated, low-privileged local attacker can create a symbolic link in a predictable location where the VPN client writes temporary or log files. When the VPN client, operating with higher privileges, attempts to access its intended file, it instead follows the malicious symbolic link and writes to or modifies an arbitrary file chosen by the attacker. This could be used to overwrite sensitive system files, leading to a local privilege escalation (LPE) and allowing the attacker to gain root-level access to the machine.
Business Impact
This vulnerability is rated as High severity with a CVSS score of 7.8. Successful exploitation could lead to a complete compromise of the affected macOS endpoint. An attacker who gains administrative or root-level privileges can bypass security controls, install persistent malware or ransomware, exfiltrate sensitive data, and potentially use the compromised machine as a pivot point to move laterally within the corporate network. This poses a significant risk to data confidentiality, integrity, and availability, particularly for organizations that rely on macOS endpoints for their workforce.
Remediation Plan
Immediate Action: The primary remediation is to apply the security updates released by the vendor across all affected macOS endpoints immediately. After patching, IT and security teams should monitor for any signs of post-exploitation activity by reviewing system and application access logs for unusual file modifications or privilege escalations that occurred prior to the patch deployment.
Proactive Monitoring: Organizations should configure Endpoint Detection and Response (EDR) tools to monitor for suspicious symbolic link creation, especially in directories used by the AWS VPN Client. Monitor file integrity for critical system files to detect unauthorized modifications. Scrutinize logs for processes running with elevated privileges that were spawned by unexpected parent processes or low-privileged user accounts.
Compensating Controls: If immediate patching is not feasible, organizations can implement compensating controls to reduce risk. This includes enforcing the principle of least privilege to limit user abilities to write to sensitive directories, using application control solutions to prevent the execution of unauthorized code, and deploying robust file integrity monitoring (FIM) to alert on changes to critical system configuration files.
Exploitation Status
Public Exploit Available: false
Analyst Notes: As of the publication date, October 7, 2025, there are no known public proof-of-concept exploits or active attacks targeting this vulnerability. However, local privilege escalation vulnerabilities are highly sought after by threat actors for post-compromise activities. It is anticipated that exploits will be developed and integrated into attacker toolkits.
Analyst Recommendation
Given the high severity (CVSS 7.8) and the significant impact of a successful local privilege escalation attack, we strongly recommend that organizations prioritize the immediate deployment of the vendor-provided security patches. Although this vulnerability is not currently listed on the CISA KEV (Known Exploited Vulnerabilities) catalog, its nature makes it a prime target for future exploitation. Proactive patching is the most effective defense to prevent the compromise of macOS endpoints within the environment.
