FKIE_CVE-2025-61037

Vulnerability from fkie_nvd - Published: 2025-12-31 16:15 - Updated: 2026-01-14 20:29
Summary
A local privilege escalation vulnerability exists in SevenCs ORCA G2 2.0.1.35 (EC2007 Kernel v5.22). The flaw is a Time-of-Check Time-of-Use (TOCTOU) race condition in the license management logic. The regService process, which runs with SYSTEM privileges, creates a fixed directory and writes files without verifying whether the path is an NTFS reparse point. By exploiting this race condition, an attacker can replace the target directory with a junction pointing to a user-controlled path. This causes the SYSTEM-level process to drop binaries in a location fully controlled by the attacker, allowing arbitrary code execution with SYSTEM privileges. The vulnerability can be exploited by any standard user with only a single UAC confirmation, making it highly practical and dangerous in real-world environments.

      "value": "Existe una vulnerabilidad de escalada de privilegios local en SevenCs ORCA G2 2.0.1.35 (EC2007 Kernel v5.22). La falla es una condici\u00f3n de carrera de Tiempo de Verificaci\u00f3n a Tiempo de Uso (TOCTOU) en la l\u00f3gica de gesti\u00f3n de licencias. El proceso regService, que se ejecuta con privilegios de SYSTEM, crea un directorio fijo y escribe archivos sin verificar si la ruta es un punto de rean\u00e1lisis NTFS. Al explotar esta condici\u00f3n de carrera, un atacante puede reemplazar el directorio de destino con una uni\u00f3n que apunta a una ruta controlada por el usuario. Esto hace que el proceso a nivel de SYSTEM coloque binarios en una ubicaci\u00f3n totalmente controlada por el atacante, permitiendo la ejecuci\u00f3n de c\u00f3digo arbitrario con privilegios de SYSTEM. La vulnerabilidad puede ser explotada por cualquier usuario est\u00e1ndar con solo una \u00fanica confirmaci\u00f3n de UAC, lo que la hace altamente pr\u00e1ctica y peligrosa en entornos del mundo real."
