CVE-2023-6342Public exploitNetwork attack vector

Account impersonation via user-controlled login parameters

Published Nov 30, 2023 · Updated Oct 15, 2024

Improper authentication in Tyler Technologies Court Case Management Plus allows remote attackers to access any user account without a password. CmWebSearchPfp/Login.aspx trusts the xyzldk username, while payforprint_CM/Redirector.ashx trusts userid, creating a session without verifying credentials. A valid username or user ID is the only gate, and impersonation exposes records and functions authorized for that account.
