CVE-2024-1403Public exploitNetwork attack vector

Unauthenticated platform access via trusted account name

Published Feb 27, 2024 · Updated Aug 12, 2024

Authentication bypass in Progress OpenEdge before 11.7.19, 12.2.14, or 12.8.1 allows remote attackers to gain unauthorized platform access. On Windows, auth.dll's authorizeUser routine accepts the supplied NT AUTHORITY/SYSTEM account name without validating its password. AdminServer logins are always exposed; Authentication Gateway exposure requires an OpenEdge Domain using the OS local authentication provider.
