CVE-2026-82524

Estado: AplazadaAlta (8.6)—

UnoPim before 2.1.5 contains an authenticated file upload vulnerability that allows authenticated administrators to upload arbitrary PHP files through the TinyMCE image upload endpoint due to missing file extension and MIME type validation. Attackers can upload a PHP web shell to the public storage disk and execute arbitrary operating system commands on the server by accessing the uploaded file at the URL returned in the server response.

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.

Acceso remoto a servicio autenticado (PR:H, AV:N) por validación deficiente de carga (CWE-434). La carga de PHP resulta en web shell (T1505.003) y ejecución de comandos del SO.

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.
