AlienVault OTX Vulnerabilities

AlienVault OTX Malware

The RupsMon.exe service executable in UPSilon 2000 has insecure permissions, allowing the 'Everyone' group Full Control. A local attacker can replace the executable with a malicious binary to execute code with SYSTEM privileges or simply change the config path of the service to a command; starting and stopping the service to immediately achieve code execution and privilege escalation

CVE-2025-66266 is a critical vulnerability classified under CWE-269 (Improper Privilege Management) affecting MegaTec Taiwan's UPSilon2000V6.0, specifically version 6.0.5. The vulnerability arises from insecure permissions on the RupsMon.exe service executable, which is part of the UPSilon2000 software suite used for uninterruptible power supply (UPS) management. The executable's permissions are set to allow the 'Everyone' group Full Control, meaning any local user can modify or replace the executable. An attacker with local access can exploit this by substituting the legitimate RupsMon.exe with a malicious binary or by changing the service's configuration path to point to a malicious command. Upon starting or stopping the service, the malicious code executes with SYSTEM-level privileges, resulting in immediate privilege escalation without requiring authentication or user interaction. The vulnerability has a CVSS 4.0 base score of 9.3, indicating critical severity, with attack vector local, low attack complexity, no privileges required, and no user interaction needed. The impact covers confidentiality, integrity, and availability, as SYSTEM-level code execution can lead to full system compromise. No patches or exploit code are currently publicly available, and no known exploits in the wild have been reported. However, the vulnerability's nature and ease of exploitation make it a significant threat to affected systems. The vulnerability was published on November 26, 2025, and assigned by Gridware. The lack of patch links suggests that remediation may require vendor coordination or manual permission adjustments. This vulnerability is particularly concerning for environments where UPSilon2000 is deployed to manage critical power infrastructure, as compromise could disrupt power management and cause cascading failures.
