CVE-2026-107639

Estado: AplazadaAlta (8.7)—

ILIAS anterior a la 9.24, 10.x anterior a la 10.12 y 11.x anterior a la 11.5 contiene una vulnerabilidad de inyección de argumentos en assImagemapQuestionGUI que permite a los autores de preguntas inyectar opciones de convert de ImageMagick mediante los nombres de archivo de las imágenes subidas. Los atacantes pueden incrustar opciones separadas por tabuladores, que escapeshellcmd() no neutraliza, para escribir un archivo PHP en la raíz web y lograr la ejecución remota de código.

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.

Vulnerabilidad de inyección de argumentos en ImageMagick explotable por autores de preguntas con acceso autenticado (PR:L) para escribir archivos PHP bajo raíz web y ejecutar código remoto; impacto de ejecución de comandos vía web shell.

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.
