Information disclosure via OBJ parser over-read
Published Jan 13, 2022 · Updated Aug 4, 2024
Out-of-bounds read in Bentley iTwin Capture Modeler 10.18.0.232 allows remote attackers to disclose data via a crafted OBJ file. The ContextCapture Viewer OBJ parser insufficiently validates file data and reads beyond the end of an allocated buffer. The target must open the file or visit a malicious page; the flaw exposes process memory and supports code execution only when chained.
