The OPC UA implementations (ANSI C and C++) in affected products contain an integer overflow vulnerability that could cause the application to run into an infinite loop during certificate validation. This could allow an unauthenticated remote attacker to create a denial of service condition by sending a specially crafted certificate.
Affected devices don't process correctly certain special crafted packets sent to port 102/tcp, which could allow an attacker to cause a denial of service in the device.

A vulnerability has been identified in SIMATIC S7-1200 CPU family (incl. SIPLUS variants) (V4.5.0). Affected devices fail to authenticate against configured passwords when provisioned using TIA Portal V13. This could allow an attacker using TIA Portal V13 or later versions to bypass authentication and download arbitrary programs to the PLC. The vulnerability does not occur when TIA Portal V13 SP1 or any later version was used to provision the device.

Siemens SIMATIC S7-1200 PLCs 2.x and 3.x allow remote attackers to cause a denial of service (defect-mode transition and control outage) via crafted packets to UDP port 161 (aka the SNMP port).
Siemens SIMATIC S7-1200 PLCs 2.x and 3.x allow remote attackers to cause a denial of service (defect-mode transition and control outage) via crafted packets to TCP port 102 (aka the ISO-TSAP port).
Cross-site scripting (XSS) vulnerability in the web server on Siemens SIMATIC S7-1200 PLCs 2.x through 3.0.1 allows remote attackers to inject arbitrary web script or HTML via a crafted URI.
The Siemens SIMATIC S7-1200 2.x PLC does not properly protect the private key of the SIMATIC CONTROLLER Certification Authority certificate, which allows remote attackers to spoof the S7-1200 web server by using this key to create a forged certificate.
