A vulnerability has been identified in JT2Go (All versions < V13.2), Solid Edge SE2021 (All Versions < SE2021MP5), Teamcenter Visualization (All versions < V13.2). 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 write past the fixed-length heap-based buffer. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-13422)

Vendor and ecosystem advisories describing this.
- SSA-173615SSA-173615: Multiple PAR and ASM File Parsing Vulnerabilities in Solid Edge2021-07-13csaf · siemens_psirtDE
Siemens has released version SE2021MP5 for Solid Edge to fix multiple heap based buffer overflow vulnerabilities that could be triggered when the application read files in PAR or ASM file formats. If a user is tricked to open a malicious file with the affected application, this could lead to a crash, and potentially also to arbitrary code execution. Siemens recommends to update to the latest version and to avoid opening of untrusted files from unknown sources.
- SSA-483182SSA-483182: Multiple File Parsing Vulnerabilities in JT2Go and Teamcenter Visualization before V13.22021-07-13csaf · siemens_psirtDE
Siemens has released version V13.2 for JT2Go and Teamcenter Visualization to fix multiple vulnerabilities that could be triggered when the products read files in different file formats (GIF, TIFF, BMP, J2K, JT, SGI, PDF, PCT, PCX, PAR and ASM ). If a user is tricked to opening of a malicious file with the affected products, this could lead to application crash, or potentially arbitrary code execution on the target host system. Siemens recommends to update to the latest versions and to limit opening of untrusted files from unknown sources in the affected products.
