mediumPriorität · verfolgen · 32EPSS 0.028 · 86. PerzentilDEEUUSEPSS · bewertet 2026-10-27
An improper check for unusual or exceptional conditions issue exists within the parsing DGN files from Drawings SDK (Version 2022.4 and prior) resulting from the lack of proper validation of the user-supplied data. This may result in several of out-of-bounds problems and allow attackers to cause a denial-of-service condition or execute code in the context of the current process.

- SSA-155599SSA-155599: File Parsing Vulnerabilities in COMOS2022-03-08csaf · siemens_psirtDE
COMOS uses Drawings SDK from Open Design Alliance that is affected by multiple vulnerabilities that could be triggered when the application reads files in DGN, DXF or DWG file formats. If a user is tricked to open a malicious file with the affected application, an attacker could leverage the vulnerability to leak information or potentially perform remote code execution in the context of the current process. Siemens has released an update for the COMOS and recommends to update to the latest version.

Siemens has released version V13.2.0.2 for JT2Go and Teamcenter Visualization to fix three vulnerabilities that could be triggered while parsing DGN or PAR files. If a user is tricked to open a malicious file with the affected products, this could lead the application to crash or potential arbitrary code execution. Siemens recommends to update to the latest versions and to limit opening of untrusted files from unknown sources in the affected products.
