Siemens » Simatic Step 7 : Security Vulnerabilities, CVEs, (Denial of service) CVSS score >= 4

A vulnerability has been identified in Opcenter Execution Discrete (All versions < V3.2), Opcenter Execution Foundation (All versions < V3.2), Opcenter Execution Process (All versions < V3.2), Opcenter Intelligence (All versions < V3.3), Opcenter Quality (All versions < V11.3), Opcenter RD&L (V8.0), SIMATIC IT LMS (All versions < V2.6), SIMATIC IT Production Suite (All versions < V8.0), SIMATIC Notifier Server for Windows (All versions), SIMATIC PCS neo (All versions < V3.0 SP1), SIMATIC STEP 7 (TIA Portal) V15 (All versions < V15.1 Update 5), SIMATIC STEP 7 (TIA Portal) V16 (All versions < V16 Update 2), SIMOCODE ES V15.1 (All versions < V15.1 Update 4), SIMOCODE ES V16 (All versions < V16 Update 1), Soft Starter ES V15.1 (All versions < V15.1 Update 3), Soft Starter ES V16 (All versions < V16 Update 1). Sending a specially crafted packet to the affected service could cause a partial remote denial-of-service, that would cause the service to restart itself.

Sending multiple specially crafted packets to the affected service could cause a partial remote denial-of-service, that would cause the service to restart itself. On some cases the vulnerability could leak random information from the remote service.

A vulnerability has been identified in SIMATIC PCS 7 V8.2 and earlier (All versions), SIMATIC PCS 7 V9.0 (All versions < V9.0 SP3), SIMATIC PDM (All versions < V9.2), SIMATIC STEP 7 V5.X (All versions < V5.6 SP2 HF3), SINAMICS STARTER (containing STEP 7 OEM version) (All versions < V5.4 HF2). A buffer overflow vulnerability could allow a local attacker to cause a Denial-of-Service situation. The security vulnerability could be exploited by an attacker with local access to the affected systems. Successful exploitation requires user privileges but no user interaction. The vulnerability could allow an attacker to compromise the availability of the system as well as to have access to confidential information.
