CVE-2025-11778

Estado: AnalizadaCrítica (10)—

Stack-based buffer overflow in Circutor SGE-PLC1000/SGE-PLC50 v0.9.2. This vulnerability allows an attacker to remotely exploit memory corruption through the 'read_packet()' function of the TACACSPLUS implementation.

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.

Stack buffer overflow en servicio remoto sin autenticación (AV:N, PR:N, UI:N). Desbordamiento de memoria permite ejecución de código (CWE-122, read_packet). CVSS crítico con VC:H/VI:H/VA:H confirma compromiso total.

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.
