Code execution via malformed X_T buffer write
Published Nov 8, 2022 · Updated Apr 21, 2025
Out-of-bounds write in Siemens Parasolid and Simcenter Femap allows remote attackers to execute code through a crafted X_T file. The X_T parser insufficiently validates user-supplied data before writing beyond the end of an allocated buffer. Exploitation requires a user to open the malicious file or visit attacker-controlled content, and resulting code runs with the current process's privileges.
