CVE-2022-3362Network attack vector

Account access via sessions surviving password changes

Published Nov 14, 2022 · Updated Apr 30, 2025

Insufficient session expiration in IKUS Software Rdiffweb before 2.5.0 allows remote attackers to retain account access after a password change. The password-change path updates account credentials without committing revocation of the account's other authenticated session records. Exploitation requires possession of an existing session credential and preserves that session's access to backup data and account functions.
