CVE-2024-47196: Siemens Modelsim

High severity, CVSS 7.3. EPSS: 0.2% chance of exploitation in the next 30 days.

A vulnerability has been identified in ModelSim (All versions < V2025.2), Questa (All versions < V2025.2). vsimk.exe in affected applications allows a specific tcl file to be loaded from the current working directory. This could allow an authenticated local attacker to inject arbitrary code and escalate privileges in installations where administrators or processes with elevated privileges launch vsimk.exe from a user-writable directory.

Affected products

• Siemens Modelsim: before 2024.3 (fixed in 2024.3)
• Siemens Questa: before 2024.3 (fixed in 2024.3)
