A vulnerability has been identified in Opcenter Quality (All versions < V2312), SIMATIC PCS neo (All versions < V4.1), SINEC NMS (All versions < V2.0 SP1), Totally Integrated Automation Portal (TIA Portal) V14 (All versions), Totally Integrated Automation Portal (TIA Portal) V15.1 (All versions), Totally Integrated Automation Portal (TIA Portal) V16 (All versions), Totally Integrated Automation Portal (TIA Portal) V17 (All versions < V17 Update 7), Totally Integrated Automation Portal (TIA Portal) V18 (All versions < V18 Update 3). The affected application contains an improper input validation vulnerability that could allow an attacker to bring the service into a Denial-of-Service state by sending a specifically crafted message to 4004/tcp. The corresponding service is auto-restarted after the crash is detected by a watchdog.

The affected application contains an out of bounds write past the end of an allocated buffer when handling specific requests on port 4002/tcp and 4004/tcp. This could allow an attacker to crash the application. The corresponding service is auto-restarted after the crash.

A reflected cross-site scripting (XSS) vulnerability exists in the web interface of the affected applications that could allow an attacker to inject arbitrary JavaScript code. The code could be potentially executed later by another (possibly privileged) user.

When accessing the UMC Web-UI from affected products, UMC uses an overly permissive CORS policy. This could allow an attacker to trick a legitimate user to trigger unwanted behavior.

A vulnerability has been identified in PCS neo (Administration Console) (All versions < V3.1), TIA Portal (V15, V15.1 and V16). Manipulating certain files in specific folders could allow a local attacker to execute code with SYSTEM privileges. The security vulnerability could be exploited by an attacker with a valid account and limited access rights on the system.

A vulnerability has been identified in TIA Portal V14 (All versions), TIA Portal V15 (All versions < V15.1 Update 7), TIA Portal V16 (All versions < V16 Update 6), TIA Portal V17 (All versions < V17 Update 4). Changing the contents of a configuration file could allow an attacker to execute arbitrary code with SYSTEM privileges. The security vulnerability could be exploited by an attacker with a valid account and limited access rights on the system. No user interaction is required. At the time of advisory publication no public exploitation of this security vulnerability was known.
