Descriptions

A vulnerability has been identified in SIMATIC STEP 7 (TIA Portal) and WinCC (TIA Portal) V10, V11, V12 (All versions), SIMATIC STEP 7 (TIA Portal) and WinCC (TIA Portal) V13 (All versions < V13 SP2 Update 2), SIMATIC STEP 7 (TIA Portal) and WinCC (TIA Portal) V14 (All versions < V14 SP1 Update 6), SIMATIC STEP 7 (TIA Portal) and WinCC (TIA Portal) V15 (All versions < V15 Update 2). Improper file permissions in the default installation of TIA Portal may allow an attacker with local file system access to insert specially crafted files which may prevent TIA Portal startup (Denial-of-Service) or lead to local code execution. No special privileges are required, but the victim needs to attempt to start TIA Portal after the manipulation.

Se ha identificado una vulnerabilidad en SIMATIC STEP 7 (TIA Portal) y WinCC (TIA Portal) V10, V11, V12 (todas las versiones); SIMATIC STEP 7 (TIA Portal) y WinCC (TIA Portal) V13 (todas las versiones anteriores a la V13 SP2 Update 2), SIMATIC STEP 7 (TIA Portal) y WinCC (TIA Portal) V14 (todas las versiones anteriores a la V14 SP1 Update 6) y SIMATIC STEP 7 (TIA Portal) and WinCC (TIA Portal) V15 (todas las versiones anteriores a la V15 Update 2). Los permisos de archivo incorrectos en la instalación por defecto de TIA Portal podría permitir que un atacante con acceso al sistema de archivos local inserte archivos especialmente manipulados que podrían evitar el arranque de TIA Portal (denegación de servicio) o conducir a la ejecución de código local. No se requieren privilegios especiales, pero la víctima debe intentar arrancar TIA Portal tras la manipulación.
