Account takeover via persistent post-change sessions
Published Mar 26, 2026 · Updated Mar 26, 2026
Session expiration failure in HCL Aftermarket DPC 1.0.0 allows remote authenticated users to retain account access after a password change. The application leaves an existing authenticated session valid when the account password changes, so the old session continues to authorize requests. An attacker must already control a valid session, and continued use preserves account control despite the legitimate user's credential reset.
