CVE-2021-22762

Code execution via unvalidated WSP and CGF paths

Published Jun 11, 2021 · Updated Aug 3, 2024

Path traversal in IGSS Definition 15.0.0.21140 and earlier allows remote attackers to execute code through a malicious WSP or CGF file. The parser uses an attacker-supplied path in file operations without validating that it remains within the intended directory. Exploitation requires a user to open or visit content that supplies a crafted project file and executes code with that user's privileges.
