Version Summary:Siemens WinCC Web Navigator contains a vulnerability that could allow an unauthenticated, remote attacker to conduct SQL injection attacks on a targeted system. Updates are available.
 
 
Description
A vulnerability in the Siemens WinCC Web Navigator application could allow an unauthenticated, remote attacker to conduct SQL injection attacks on a targeted system.

The vulnerability is due to insufficient sanitization of user-supplied input by the WinCC Web Navigator login screen before the input is used in a SQL query. An attacker could exploit this vulnerability by sending crafted SQL statements to the login screen of the affected application, allowing injection of SQL statements into queries. An exploit could allow the attacker to execute arbitrary SQL queries on the underlying database, which could be used to conduct further attacks.

Siemens has confirmed this vulnerability and released updated software.
 
Warning Indicators
The following Siemens products are affected:
  • WinCC versions 7.2 and prior
  • SIMATIC PCS7 versions 8.0 SP1 and prior
 
IntelliShield Analysis
To exploit the vulnerability, the attacker must submit malicious requests to the targeted system. In a typical network configuration, the attacker must access trusted, internal networks to submit malicious requests to the system. This access requirement could reduce the likelihood of a successful exploit.
