The TeleMessage archiving backend through 2025-05-05 holds cleartext copies of messages from TM SGNL (aka Archive Signal) app users, which is different functionality than described in the TeleMessage "End-to-End encryption from the mobile phone through to the corporate archive" documentation, as exploited in the wild in May 2025.

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).

CISA KEV — explotada activamente

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N con PR:H y acceso a backend de archiving (servicios remotos requieren privilegios elevados). Impacto: acceso a copias en texto plano de mensajes (T1005 lectura de datos sensibles) y credenciales potenciales en logs/caché (T1552.007).

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.
