CVE-2022-42899

Code execution via malformed SKP parsing

Published Oct 13, 2022 · Updated May 15, 2025

Out-of-bounds read and stack overflow flaws in MicroStation and Bentley View 10.17.0.* and earlier allow attackers to execute code via SKP files. The SKP parser reads beyond a buffer boundary or exhausts its stack while processing maliciously crafted file data. Context-dependent attackers must induce the current user to open the file; successful exploitation reads process data or executes code with that user's privileges.
