CVE-2023-38681

Code execution via unchecked IGS buffer write

Published Aug 8, 2023 · Updated Oct 11, 2024

Out-of-bounds write in Tecnomatix Plant Simulation V2201 before V2201.0008 and V2302 before V2302.0002 allows attackers to execute code. The IGS parser fails to validate user-supplied file data before writing past the end of an allocated buffer. Exploitation requires a user to open a crafted IGS file, after which code runs with the current process's privileges and the application can crash.
