CVE-2019-19362

Estado: ModificadaMedia (6.5)—

Se detectó un problema en la funcionalidad Chat de la aplicación de escritorio TeamViewer versión 14.3.4730 en Windows. (El proveedor declara que luego fue corregido). Tras iniciar sesión, cada comunicación es guardada en la memoria principal de Windows. Cuando un usuario cierra sesión o elimina el historial de conversación (pero no sale de la aplicación), estos datos no son borrados de la memoria principal y, por lo tanto, un usuario local puede leerlos con los mismos o mayores privilegios.

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).
