Roundcube Webmail 1.6.x before 1.6.16 and 1.7.x before 1.7.1 has insecure code evaluation logic in LDAP the autovalues option that could lead to code injection. (Support for code evaluation has been removed in 1.6.16 and 1.7.1.)

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.

LDAP autovalues code injection en servicio web remoto con PR:L permite ejecución de código arbitrario; acceso a credenciales LDAP posible como impacto secundario.

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.
