CVE-2021-31343
mediumpriority · track · 36EPSS 0.025 · 85 %ileDEEURUUSEPSS · scored 2026-10-27
The jutil.dll library in all versions of Solid Edge SE2020 before 2020MP14 and all versions of Solid Edge SE2021 before SE2021MP5 lack proper validation of user-supplied data when parsing DFT files. This could result in an out-of-bounds write past the end of an allocation structure. An attacker could leverage this vulnerability to execute code in the context of the current process.

Vendor and ecosystem advisories describing this.
- SSA-208356SSA-208356: DFT File Parsing Vulnerabilities in Solid Edge2021-06-08csaf · siemens_psirtDE
Siemens has released a new version for Solid Edge to fix two vulnerabilities that could be triggered when the application read files in DFT file format. 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.
