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.

Detection & IOCsextracted from sources · hover to see the quote

port4444/TCP
  • Detect unauthenticated inbound connections to TCP port 4444 targeting SIMATIC Energy Manager, which is the service port used for the insecure deserialization attack vector.
  • Alert on deserialization of untrusted/user-supplied objects arriving over the network without authentication, leading to SYSTEM-level code execution on SIMATIC Energy Manager Basic/PRO versions prior to v7.3 Update 1.
  • ·Encryption is not enabled by default in SIMATIC Energy Manager; enabling it is a recommended mitigation to reduce exposure to this deserialization vulnerability.
  • ·No known public exploits specifically targeting CVE-2022-23450 were identified at the time of advisory publication.
