An issue in Unistal Systems Pvt. Ltd.Protegent 360 v2.0.0.4 allows a local attacker to escalate privileges via the sub_186f4 function
AnalysisAI
Local privilege escalation in Unistal Systems Protegent 360 v2.0.0.4 allows a low-privileged attacker to gain SYSTEM-level control through the sub_186f4 function. A publicly available proof-of-concept exists, but no active exploitation is currently reported and the EPSS estimate of 0.19% suggests low threat actor interest.
Technical ContextAI
The vulnerability resides in the sub_186f4 function of Protegent 360, a third-party antivirus product, and is classified as Improper Privilege Management (CWE-269). The function fails to restrict privileges correctly, allowing a local user with minimal permissions to execute code in a higher-integrity context. The affected product is identified as Unistal Systems Protegent 360 version 2.0.0.4; no precise CPE match exists beyond the generic n/a placeholder, limiting automated asset correlation.
RemediationAI
No vendor-released patch has been identified at the time of this analysis. Mitigation requires strict control over local user accounts and application whitelisting to prevent untrusted code execution. If the software is not essential, consider temporary removal; if it must remain, monitor for suspicious privilege escalation events via EDR and audit sensitive function calls. The referenced advisory may contain further technical workarounds-consult the vendor’s official channel for updates.
