Code execution via DFT parser out-of-bounds write
Published Jan 12, 2021 · Updated Aug 4, 2024
Out-of-bounds write in Siemens Solid Edge allows attackers to execute code in the current process through a crafted DFT file. The DFT parser fails to validate user-supplied file data before writing past the end of an allocated structure. Exploitation requires a user to open the file or visit a malicious page and affects SE2020 before SE2020MP12 and SE2021 before SE2021MP2.
