User impersonation via victim session ID reuse
Published Mar 2, 2020 · Updated Aug 4, 2024
Session management failure in GRANDIT 1.6, 2.0, 2.1, 2.2, 2.3, and 3.0 allows remote attackers to impersonate users and read or alter data. The application fails to prevent reuse of a victim's login-associated session ID, allowing that identifier to authorize later screen requests. Exploitation requires victim interaction and possession of the victim's session ID, and access is bounded by the impersonated account.
