CVE-2024-7252 is a local privilege escalation vulnerability identified in Comodo Internet Security Pro, specifically affecting version 12.2.4.8032. The vulnerability stems from improper handling of symbolic links (CWE-59) in the cmdagent executable component. An attacker who already has the ability to execute code with low privileges on the target system can exploit this flaw by creating a symbolic link that tricks the cmdagent process into deleting an arbitrary file. This improper link resolution before file access allows the attacker to escalate their privileges to SYSTEM level, effectively gaining full control over the affected machine. The vulnerability does not require user interaction but does require local access and some level of code execution capability. The CVSS v3.0 score is 7.8 (high), reflecting the significant impact on confidentiality, integrity, and availability, combined with relatively low attack complexity and privileges required. No patches or exploits are currently publicly available, but the vulnerability was assigned and published by the Zero Day Initiative (ZDI) under ZDI-CAN-22831. This flaw highlights the risks associated with insufficient validation of symbolic links in security software components that run with elevated privileges.

If exploited, this vulnerability allows an attacker with limited local access to escalate privileges to SYSTEM level, which can lead to complete system compromise. This includes the ability to execute arbitrary code with the highest privileges, potentially bypassing security controls, installing persistent malware, stealing sensitive data, or disrupting system availability. The impact extends to any organization using the affected Comodo Internet Security Pro version, especially those with sensitive or critical infrastructure. Because the vulnerability requires local code execution, it is particularly dangerous in environments where attackers can gain initial footholds through other means such as phishing, insider threats, or compromised accounts. The ability to escalate privileges can facilitate lateral movement and deeper penetration into enterprise networks, increasing the overall risk posture.

1. Immediately restrict local user permissions to prevent unauthorized code execution and symbolic link creation. 2. Monitor and audit file system activities, especially creation of symbolic links and deletion of critical files by the cmdagent process. 3. Employ application whitelisting and endpoint detection and response (EDR) solutions to detect suspicious behavior related to privilege escalation attempts. 4. Isolate systems running Comodo Internet Security Pro to limit local access to trusted users only. 5. Once available, apply vendor patches or updates addressing this vulnerability without delay. 6. Consider temporary workarounds such as disabling or limiting the cmdagent service if feasible and safe to do so. 7. Educate users and administrators about the risks of local code execution and enforce strict access controls. 8. Conduct regular vulnerability assessments and penetration testing to identify and remediate privilege escalation vectors.
