CVE-2021-31342: Siemens Solid Edge SE2020 Firmware

High severity, CVSS 8.8. EPSS: 2.5% chance of exploitation in the next 30 days.

The ugeom2d.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 allocated structure. An attacker could leverage this vulnerability to execute code in the context of the current process.

Affected products

• Siemens Solid Edge SE2020 Firmware: before 2020mp14 (fixed in 2020mp14)
• Siemens Solid Edge SE2021 Firmware: before se2021mp5 (fixed in se2021mp5)
