Summary
SSA-348662: Multiple Vulnerabilities in SIMATIC MV500 Devices before V3.3
Notes
Summary
SIMATIC MV500 devices before V3.3 are affected by multiple vulnerabilities that could allow attackers to hijack other users' web based management sessions (CVE-2022-33137) or access data on the device without prior authentication (CVE-2022-33138).
Siemens has released an update for the SIMATIC MV500 devices and recommends to update to the latest version. Note that the update also contains additional fixes for vulnerabilities documented in Siemens Security Advisory SSA-712929.
General Recommendations
As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals.
