CVE-2014-4686

Status Candidate

Overview

The Project administration application in Siemens SIMATIC WinCC before 7.3, as used in PCS7 and other products, has a hardcoded encryption key, which allows remote attackers to obtain sensitive information by extracting this key from another product installation and then employing this key during the sniffing of network traffic on TCP port 1030.

Siemens SIMATIC WinCC (TIA Portal) V13 Privilege Escalation
Posted Feb 16, 2015
Authored by Siemens ProductCERT | Site siemens.com

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.
