EPSS · scored 2026-10-27

A vulnerability has been identified in JT2Go (All versions < V13.2.0.2), Teamcenter Visualization (All versions < V13.2.0.2). The plmxmlAdapterSE70.dll library in affected applications lacks proper validation of user-supplied data when parsing PAR files. This could result in an out of bounds read past the end of an allocated buffer. An attacker could leverage this vulnerability to leak information in the context of the current process. (ZDI-CAN-13405)

  • SSA-938030SSA-938030: DGN and PAR File Parsing Vulnerabilities in JT2Go and Teamcenter Visualization before V13.2.0.22021-08-10csaf · siemens_psirtDE

    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. Note: - This advisory also covers security vulnerabilities recently disclosed by Open Design Alliance [0] [0] https://www.opendesign.com/security-advisories
