Code execution via CG4 out-of-bounds read
Published Jan 12, 2021 · Updated Aug 4, 2024
Out-of-bounds read in Siemens JT2Go and Teamcenter Visualization before 13.1.0 allows remote attackers to execute code via a crafted CG4 file. The CG4 parser fails to validate user-controlled data before reading beyond the end of an allocated buffer, enabling control of the current process. Exploitation requires the target to open the malicious file or visit a page that supplies it, and successful execution inherits the target process's privileges.
