CVE-2026-57878

Estado: AplazadaCrítica (9.8)—

An unauthenticated stack-based buffer overflow vulnerability exists in thttpd in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient bounds checking when processing web request parameters in a specific request path. A remote attacker may exploit this vulnerability by sending a crafted HTTP request with overly long input, resulting in memory corruption, denial of service, or potentially arbitrary code execution.

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 remoto sin autenticación en servicio web expuesto (AV:N, PR:N, UI:N). Potencial ejecución de código arbitrario y DoS por corrupción de memoria en stack.

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.
