MITRE ATT&CK
1 technique across 1 tactic: Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Requires local authenticated access to a machine running Protegent 360 version 2.0.0.4. The attacker must hold a low-privilege user account (standard user). No user interaction is needed, and the function is exploitable in its default configuration with no additional settings required. |
| Impact | The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) reflects a severe local impact-complete system compromise once exploited-but requires authenticated, interactive access to the endpoint. EPSS is very low (0.19%, 9th percentile), indicating the exploit is unlikely to be used in mass attacks. The CISA SSVC analysis marks the exploitation as Proof-of-Concept only, not automatable, and total technical impact. This is a real risk for environments where unprivileged local access is common (e.g., shared workstations, terminal servers), but otherwise the low EPSS and lack of active exploitation reduce its urgency. |
| Exploit ScenarioDerived | A low-privileged user (e.g., a guest or standard account) obtains local access to the endpoint and executes the publicly available proof-of-concept that triggers improper privilege management in sub_186f4, instantly elevating to SYSTEM and enabling complete system takeover. |

Alert meAnalysisAIv1 – Jul 26, 2026
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.
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.

Technical ContextAI · show details
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.
