SSA-493396: Deserialization Vulnerability in Siemens Engineering Platforms

view advisory published 2025-08-12

Affected products do not properly sanitize user-controllable input when parsing project files. This could allow an attacker to cause a type confusion and execute arbitrary code within the affected application. Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens is preparing further fix versions and recommends specific countermeasures for products where fixes are not, or not yet available.
