Known Vulnerabilities
CVE-2021-31893
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). The affected software contains a buffer overflow vulnerability while handling certain files that could allow a local attacker to trigger a denial-of-service condition or potentially lead to remote code execution.
CVE-2020-7586
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.
CVE-2020-7585
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 DLL Hijacking vulnerability could allow a local attacker to execute code with elevated privileges. 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.
CVE-2019-19282
A vulnerability has been identified in OpenPCS 7 V8.1 (All versions), OpenPCS 7 V8.2 (All versions), OpenPCS 7 V9.0 (All versions < V9.0 Upd3), SIMATIC BATCH V8.1 (All versions), SIMATIC BATCH V8.2 (All versions < V8.2 Upd12), SIMATIC BATCH V9.0 (All versions < V9.0 SP1 Upd5), SIMATIC NET PC Software V14 (All versions < V14 SP1 Update 14), SIMATIC NET PC Software V15 (All versions), SIMATIC NET PC Software V16 (All versions < V16 Update 1), SIMATIC PCS 7 V8.1 (All versions), SIMATIC PCS 7 V8.2 (All versions), SIMATIC PCS 7 V9.0 (All versions < V9.0 SP3), SIMATIC Route Control V8.1 (All versions), SIMATIC Route Control V8.2 (All versions), SIMATIC Route Control V9.0 (All versions < V9.0 Upd4), SIMATIC WinCC (TIA Portal) V13 (All versions < V13 SP2), SIMATIC WinCC (TIA Portal) V14 (All versions < V14 SP1 Update 10), SIMATIC WinCC (TIA Portal) V15.1 (All versions < V15.1 Update 5), SIMATIC WinCC (TIA Portal) V16 (All versions < V16 Update 1), SIMATIC WinCC V7.3 (All versions), SIMATIC WinCC V7.4 (All versions < V7.4 SP1 Update 14), SIMATIC WinCC V7.5 (All versions < V7.5 SP1 Update 1). Through specially crafted messages, when encrypted communication is enabled, an attacker with network access could use the vulnerability to compromise the availability of the system by causing a Denial-of-Service condition. Successful exploitation requires no system privileges and no user interaction.
