A vulnerability has been identified in SIMATIC Energy Manager Basic (All versions < V7.5), SIMATIC Energy Manager PRO (All versions < V7.5), SIMATIC IPC DiagBase (All versions), SIMATIC IPC DiagMonitor (All versions), SIMIT V10 (All versions), SIMIT V11 (All versions < V11.1). Unified Automation .NET based OPC UA Server SDK before 3.2.2 used in Siemens products are affected by a similar vulnerability as documented in CVE-2023-27321 for the OPC Foundation UA .NET Standard implementation. A successful attack may lead to high load situation and memory exhaustion, and may block the server.

A vulnerability has been identified in SIMATIC Energy Manager Basic (All versions < V7.3 Update 1), SIMATIC Energy Manager PRO (All versions < V7.3 Update 1). The affected system allows remote users to send maliciously crafted objects. Due to insecure deserialization of user-supplied content by the affected software, an unauthenticated attacker could exploit this vulnerability by sending a maliciously crafted serialized object. This could allow the attacker to execute arbitrary code on the device with SYSTEM privileges.

A vulnerability has been identified in SIMATIC Energy Manager Basic (All versions < V7.3 Update 1), SIMATIC Energy Manager PRO (All versions < V7.3 Update 1). A DLL Hijacking vulnerability could allow a local attacker to execute code with elevated privileges by placing a malicious DLL in one of the directories on the DLL search path.

A vulnerability has been identified in SIMATIC Energy Manager Basic (All versions < V7.3 Update 1), SIMATIC Energy Manager PRO (All versions < V7.3 Update 1). Affected applications improperly assign permissions to critical directories and files used by the application processes. This could allow a local unprivileged attacker to achieve code execution with ADMINISTRATOR or even NT AUTHORITY/SYSTEM privileges.
