CVE-2023-3953

Memory corruption via tampered log file

Published Aug 9, 2023 · Updated Oct 9, 2024

Memory corruption in Schneider Electric WinGP 4.09.450 and earlier allows attackers to corrupt memory via a tampered GP-Pro EX log file. The vendor identifies log-file handling as the trigger but does not disclose the parser, malformed field, or exact out-of-bounds operation. A logged-in user must open the attacker-supplied file; the documented consequence is memory corruption with low confidentiality, integrity, and availability impact.
