TITLE
Siemens' ModelSim Simulation and Questa Simulation Vulnerability regarding uncontrolled search path elements in
Trust: 0.8
DESCRIPTION
A vulnerability has been identified in ModelSim (All versions < V2025.1), Questa (All versions < V2025.1). An example setup script contained in affected applications allows a specific executable 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 the script from a user-writable directory. Siemens' ModelSim Simulation and Questa Simulation Exists in a vulnerability in an element of an uncontrolled search path.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. ModelSim is an industry-leading hardware description language (HDL) simulation tool developed by Mentor Graphics (now a Siemens company), mainly used for verification and debugging of digital circuit designs. Questa is an intelligent verification solution launched by Siemens, which aims to optimize the integrated circuit (IC) verification process through artificial intelligence (AI) technology, improve production efficiency and meet complex design challenges
