Descriptions

The remote-management module in the (1) Multi Panels, (2) Comfort Panels, and (3) RT Advanced functionality in Siemens SIMATIC WinCC (TIA Portal) before 13 SP1 and in the (4) panels and (5) runtime functionality in SIMATIC WinCC flexible before 2008 SP3 Up7 does not properly encrypt credentials in transit, which makes it easier for remote attackers to determine cleartext credentials by sniffing the network and conducting a decryption attack.

El módulo de administración remota en la funcionalidad (1) Multi Panels (2) Comfort Panels y (3) RT Advanced en Siemens SIMATIC WinCC (TIA Portal) en versiones anteriores a 13 SP1 y en la funcionalidad (4) panels y (5) runtime en SIMATIC WinCC flexible en versiones anteriores a 2008 SP3 Up7 no cifra correctamente las credenciales en tránsito, lo que hace que sea más fácil a atacantes remotos determinar las credenciales en texto plano rastreando la red y llevando a cabo un ataque de descifrado.

The latest update for SIMATIC WinCC (TIA Portal) V13 fixes two vulnerabilities. The remote management module of WinCC (TIA Portal) Multi Panels and Comfort Panels, and WinCC RT Advanced transmits weakly protected credentials over the network. Attackers capturing network traffic of the remote management module could possibly reconstruct used passwords. A hard coded encryption key used in WinCC RT Professional could allow attackers to escalate their privileges if the application's network communication with an authenticated user was captured.
