CVE-2018-13799: A vulnerability has been identified in SIMATIC WinCC OA V3.14 and prior (All versions < V3.14-P021).

A vulnerability has been identified in SIMATIC WinCC OA V3.14 and prior (All versions < V3.14-P021). Improper access control to a data point of the affected product could allow an unauthenticated remote user to escalate its privileges in the context of SIMATIC WinCC OA V3.14. This vulnerability could be exploited by an attacker with network access to port 5678/TCP of the SIMATIC WinCC OA V3.14 server. Successful exploitation requires no user privileges and no user interaction. This vulnerability could allow an attacker to compromise integrity and availability of the SIMATIC WinCC OA system. At the time of advisory publication no public exploitation of this vulnerability was known.

Security readout for executives and security teams

CVE-2018-13799 affects Siemens SIMATIC WinCC OA V3.14 and earlier builds before V3.14-P021. A remote unauthenticated attacker with network access to TCP port 5678 could gain higher privileges in the WinCC OA context, potentially disrupting system integrity and availability. Exposure is most likely in environments running SIMATIC WinCC OA V3.14 or prior where TCP port 5678 is reachable from untrusted or poorly segmented networks. Prioritize this for OT environments because exploitation needs no credentials and could affect availability or integrity of industrial monitoring systems. Mitigation focus: Review Siemens SSA-346256 for official remediation guidance.; Upgrade affected SIMATIC WinCC OA V3.14 systems to V3.14-P021 or later where applicable.; Restrict TCP port 5678 to trusted management and application hosts only..
