CVE-2024-30321
Estado: AplazadaAlta (8.2)—
A vulnerability has been identified in SIMATIC PCS 7 V9.1 (All versions < V9.1 SP2 UC05), SIMATIC WinCC Runtime Professional V18 (All versions < V18 Update 5), SIMATIC WinCC Runtime Professional V19 (All versions < V19 Update 2), SIMATIC WinCC V7.4 (All versions < V7.4 SP1 Update 23), SIMATIC WinCC V7.5 (All versions < V7.5 SP2 Update 17), SIMATIC WinCC V8.0 (All versions < V8.0 Update 5). The affected products do not properly handle certain requests to their web application, which may lead to the leak of privileged information. This could allow an unauthenticated remote attacker to retrieve information such as users and passwords.
