CVE-2024-7238 is a high-severity local privilege escalation vulnerability affecting VIPRE Advanced Security version 12.0.1.214. The flaw resides in the Anti Malware Service (SBAMSvc), which improperly resolves symbolic links before performing file operations, a classic example of CWE-59: Improper Link Resolution Before File Access ('Link Following'). An attacker who has already gained the ability to execute code with low privileges on the affected system can exploit this vulnerability by creating a malicious symbolic link. This link tricks the service into deleting arbitrary files, which can be leveraged to escalate privileges to SYSTEM level. The vulnerability does not require user interaction but does require local access and some level of code execution capability. The CVSS 3.0 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) indicates that the attack vector is local, with low attack complexity and low privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability. Although no public exploits are known at this time, the vulnerability poses a significant risk due to the potential for full system compromise. The issue was reserved by ZDI and published in November 2024, but no patches have been linked yet, indicating that remediation may still be pending or in progress.

If exploited, this vulnerability allows an attacker with limited local access to escalate their privileges to SYSTEM, effectively gaining full control over the affected machine. This can lead to unauthorized access to sensitive data, modification or deletion of critical files, and disruption of security services provided by VIPRE Advanced Security. The compromise of SYSTEM privileges can facilitate further lateral movement within a network, persistence, and deployment of malware or ransomware. Organizations relying on VIPRE Advanced Security for endpoint protection could see their defenses bypassed, increasing the risk of broader compromise. The high impact on confidentiality, integrity, and availability underscores the critical nature of this vulnerability, especially in environments with multiple users or shared systems.

Until an official patch is released, organizations should implement strict local access controls to limit the ability of unprivileged users to execute code on systems running VIPRE Advanced Security 12.0.1.214. Employ application whitelisting and endpoint detection to prevent unauthorized code execution. Monitor and audit file system changes and symbolic link creations in directories accessed by the Anti Malware Service. Consider temporarily disabling or restricting the Anti Malware Service if feasible and safe to do so, or running it with the least privileges necessary. Once a patch becomes available, prioritize its deployment across all affected systems. Additionally, educate users about the risks of executing untrusted code locally and maintain robust incident response plans to detect and respond to potential exploitation attempts.
