CVE-2024-7239 is a local privilege escalation vulnerability affecting VIPRE Advanced Security version 12.0.1.214. The root cause is improper link resolution before file access (CWE-59) within the Anti Malware Service component. This service, running with elevated privileges, improperly handles symbolic links created by a local attacker. By crafting a symbolic link that points to a sensitive file, the attacker can trick the service into deleting or modifying files it should not have access to. This flaw allows an attacker who already has the ability to execute low-privileged code on the system to escalate their privileges to SYSTEM level, thereby gaining full control over the affected machine. The vulnerability does not require user interaction and has a relatively low attack complexity, but it requires local code execution privileges initially. The CVSS v3.0 score is 7.8, reflecting high impact on confidentiality, integrity, and availability due to the potential for arbitrary code execution as SYSTEM. No public exploits or patches have been reported yet, but the vulnerability was assigned and published by the Zero Day Initiative (ZDI) under ZDI-CAN-22314. This vulnerability is particularly dangerous because it leverages a trusted security service to perform unauthorized file operations, undermining the security guarantees of the endpoint protection software itself.

The primary impact of CVE-2024-7239 is local privilege escalation, allowing attackers with limited access to gain full SYSTEM privileges on affected endpoints. This can lead to complete system compromise, including the ability to disable security controls, install persistent malware, exfiltrate sensitive data, or move laterally within a network. Organizations relying on VIPRE Advanced Security 12.0.1.214 for endpoint protection could see their defenses bypassed if this vulnerability is exploited. The attack requires initial local code execution, so it is most dangerous in environments where attackers can already run code with user-level privileges, such as through phishing, malicious insiders, or other initial footholds. The vulnerability threatens confidentiality, integrity, and availability of systems, potentially impacting critical infrastructure, enterprise networks, and sensitive data environments. Although no exploits are known in the wild yet, the high CVSS score and the nature of the flaw suggest a strong incentive for attackers to develop exploits quickly.

To mitigate CVE-2024-7239, organizations should first verify if they are running VIPRE Advanced Security version 12.0.1.214 and prioritize upgrading to a patched version once available. Until a patch is released, restrict local user permissions to prevent unauthorized code execution, as the vulnerability requires initial low-privileged code execution. Employ application whitelisting and endpoint detection and response (EDR) solutions to detect suspicious symbolic link creation or unauthorized file deletions by the Anti Malware Service. Monitor system logs for unusual activity related to the VIPRE service and symbolic link operations. Consider isolating critical systems and limiting local user access to reduce the attack surface. Additionally, coordinate with VIPRE support or vendor advisories for any interim mitigations or workarounds. Regularly audit endpoint security configurations to ensure that privileged services do not follow untrusted symbolic links. Finally, educate users and administrators about the risks of local code execution vulnerabilities and enforce strong access controls.
