EPSS · scored 2026-10-27

A vulnerability has been identified in NX 1980 Series (All versions < V1984), Solid Edge SE2021 (All versions < SE2021MP8). The plmxmlAdapterIFC.dll contains an out-of-bounds read while parsing user supplied IFC files which could result in a read past the end of an allocated buffer. This could allow an attacker to cause a denial-of-service condition or read sensitive information from memory locations.

  • SSA-208530SSA-208530: File parsing vulnerabilities in IFC adapter in NX2021-09-14csaf · siemens_psirtDE

    Siemens NX is affected by two vulnerabilities that could be triggered when the application reads ifc files. If a user is tricked to open a malicious file with the affected application, this could lead to an access violation, and potentially also to arbitrary code execution on the target host system. Siemens has released updates for NX and recommends to update to the latest version to fix the vulnerabilities. Siemens recommends to avoid opening of untrusted files from unknown sources.

  • SSA-728618SSA-728618: Multiple Vulnerabilities in Solid Edge before SE2021MP82021-09-28csaf · siemens_psirtDE

    Siemens has released a new version for Solid Edge that fixes multiple file parsing vulnerabilities which could be triggered when the application reads files in IFC, JT or OBJ formats. 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 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.
