CVE-2020-7492

Password disclosure via unmasked password entry

Published Jun 16, 2020 · Updated Aug 4, 2024

Weak password handling in Schneider Electric GP-Pro EX 1.00 through 4.09.100 allows local users to discover passwords during entry. The password-entry control renders entered characters without masking them, leaving the typed password visible on the application display. Exploitation requires a user to enter a password while an attacker can observe that display; the bounded consequence is password disclosure.
