Detailsinfo

A vulnerability classified as critical was found in Siemens SIMATIC HMI Comfort Panel, SIMATIC HMI Comfort Outdoor Panel, SIMATIC HMI KTP Mobile Panel and SIMATIC WinCC (SCADA Software) (the affected version is unknown). This vulnerability affects an unknown code of the component Webserver. The manipulation with an unknown input leads to a input validation vulnerability (Header Injection). The CWE definition for the vulnerability is CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

A vulnerability has been identified in SIMATIC HMI Comfort Panels 4" - 22" (All versions < V14), SIMATIC HMI Comfort Outdoor Panels 7" & 15" (All versions < V14), SIMATIC HMI KTP Mobile Panels KTP400F, KTP700, KTP700F, KTP900 and KTP900F (All versions < V14), SIMATIC WinCC Runtime Advanced (All versions < V14), SIMATIC WinCC Runtime Professional (All versions < V14), SIMATIC WinCC (TIA Portal) (All versions < V14), SIMATIC HMI Classic Devices (TP/MP/OP/MP Mobile Panel) (All versions). The integrated web server (port 80/tcp and port 443/tcp) of the affected devices could allow an attacker to inject HTTP headers. An attacker must trick a valid user who is authenticated to the device into clicking on a malicious link to exploit the vulnerability. At the time of advisory publication no public exploitation of this security vulnerability was known.
