A vulnerability has been identified in SIMATIC MV540 H (All versions < V3.3), SIMATIC MV540 S (All versions < V3.3), SIMATIC MV550 H (All versions < V3.3), SIMATIC MV550 S (All versions < V3.3), SIMATIC MV560 U (All versions < V3.3), SIMATIC MV560 X (All versions < V3.3). The web session management of affected devices does not invalidate session ids in certain logout scenarios. This could allow an authenticated remote attacker to hijack other users' sessions.
In ArangoDB, versions v3.7.6 through v3.8.3 are vulnerable to Insufficient Session Expiration. When a user’s password is changed by the administrator, the session isn’t invalidated, allowing a malicious user to still be logged in and perform arbitrary actions within the system.
