SSA-017796: Multiple File Parsing Vulnerabilities in Tecnomatix Plant Simulation

Publication Date:	2024-02-13
Last Update:	2024-02-13
Current Version:	V1.0
CVSS v3.1 Base Score:	7.8
CVSS v4.0 Base Score:	7.3

SUMMARY

Siemens Tecnomatix Plant Simulation contains multiple file parsing vulnerabilities that could be triggered when the application reads files in WRL, PSOBJ or SPP file formats. If a user is tricked to open a malicious file with any of the affected products, this could lead the application to crash or potentially lead to arbitrary code execution.

Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens recommends specific countermeasures for products where fixes are not, or not yet available.
