A vulnerability has been identified in Solid Edge SE2021 (All Versions < SE2021MP7). The PSKERNEL.dll library lacks proper validation while parsing user-supplied OBJ files that could cause an out of bounds access to an uninitialized pointer. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-13775)

advisories (2)

Vendor and ecosystem advisories describing this.

SSA-818688SSA-818688: Multiple Vulnerabilities in Solid Edge before SE2021MP72021-08-10csaf · siemens_psirtDE
Siemens has released a new version for Solid Edge that fixes three vulnerabilities - an XML external entity (XXE) injection, and two file parsing issues which could be triggered when the application reads OBJ files. If a user is tricked to opening a malicious file using the affected application this could lead the application to crash, or potentially arbitrary code execution and data extraction on the target host system. Siemens recommends to update to the latest version and to limit opening of files from unknown sources in the affected products.
