CVE-2026-2731

Estado: AplazadaCrítica (10)—

Path traversal and content injection in JobRunnerBackground.aspx in DynamicWeb 8 (all) and 9 (<9.19.7 and <9.20.3) allows unauthenticated attackers to execute code via simple web requests

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 sin autenticación (PR:N) permite explotación remota de path traversal (CWE-22) en aplicación web expuesta. El acceso a JobRunnerBackground.aspx sin credenciales y la inyección de contenido permiten ejecución de código y lectura de datos.

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.
