CVE-2026-22905

Estado: AplazadaAlta (7.5)—

An unauthenticated remote attacker can bypass authentication by exploiting insufficient URI validation and using path traversal sequences (e.g., /js/../cgi-bin/post.cgi), gaining unauthorized access to protected CGI endpoints and configuration downloads.

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.

AV:N/PR:N/UI:N indica explotación remota sin autenticación (T1190). Path traversal (CWE-22) permite acceso a archivos protegidos y endpoints CGI, logrando lectura de datos de configuración (T1005).

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.
