CVE-2025-11779

Estado: AnalizadaCrítica (9.4)—

Stack-based buffer overflow vulnerability in CircutorSGE-PLC1000/SGE-PLC50 v9.0.2. The 'SetLan' function is invoked when a new configuration is applied. This new configuration function is activated by a management web request, which can be invoked by a user when making changes to the 'index.cgi' web application. The parameters are not being sanitised, which could lead to command injection.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Buffer overflow en función SetLan accesible vía web (AV:A, PR:L) sin UI:R permite inyección de comandos remota. Stack overflow + command injection = ejecución de código con potencial escalada (VI:H, VA:H en firmware).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
