Technical details
A vulnerability (CWE-525) exists in the web-based management interface of Siemens RUGGEDCOM RST2428P switches running SINEC OS. The application fails to prevent the browser from caching sensitive information during configuration changes. An authenticated attacker with network access could exploit this by enticing a user to perform configuration tasks and then accessing the cached data through the user's browser. This requires user interaction and prior authentication. Siemens has addressed this issue in SINEC OS V4.0 and recommends that users update their firmware to the latest version.
