CVE-2025-22926

Estado: AnalizadaCrítica (9.8)—

An issue in OS4ED openSIS v8.0 through v9.1 allows attackers to execute a directory traversal by sending a crafted POST request to /Modules.php?modname=messaging/Inbox.php&modfunc=save&filename.

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). CWE-22 (directory traversal) permite lectura de archivos del sistema (T1005) y potencialmente manipulación de datos (T1565) al acceder a ficheros sensibles vía POST crafted.

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.
