CVE-2024-5040

Code execution via unvalidated LGX report paths

Published May 21, 2024 · Updated Aug 1, 2024

Path traversal in LCDS LAquis SCADA 4.7.1.7 and earlier allows remote attackers to execute code through a malicious LGX report. The LGX processor passes attacker-controlled paths to Table.Save, STRING file methods, File.Open, TextFile methods, and AddComboFile without restricting file access to the project directory. A target must visit a malicious page or open a malicious file; exploitation runs code as the current user, while one path reads process-accessible files.
