Code execution via freed DWG parser object
Published Aug 8, 2023 · Updated Oct 11, 2024
Use-after-free in Siemens Solid Edge SE2023 before 223.0 Update 2 allows context-dependent attackers to execute code via a crafted DWG file. The DWG parser performs operations on an object without first validating that it still exists, permitting access after the object is freed. Exploitation requires a user to open the file or visit a malicious page, and resulting code runs in the current process context.
