Siemens: >> Sinamics S120 Firmware Security Vulnerabilities
A vulnerability has been identified in SIMATICÂ PC-Station Plus (All versions), SIMATIC S7-400 CPU 412-2 PN V7 (All versions), SIMATIC S7-400 CPU 414-3 PN/DP V7 (All versions), SIMATIC S7-400 CPU 414F-3 PN/DP V7 (All versions), SIMATIC S7-400 CPU 416-3 PN/DP V7 (All versions), SIMATIC S7-400 CPU 416F-3 PN/DP V7 (All versions), SINAMICS S120 (incl. SIPLUS variants) (All versions < V5.2 SP3 HF15), SIPLUS S7-400 CPU 414-3 PN/DP V7 (All versions), SIPLUS S7-400 CPU 416-3 PN/DP V7 (All versions). The affected products do not handle HTTP(S) requests to the web server correctly.
This could allow an attacker to exhaust system resources and create a denial of service condition for the device.

The webserver of the affected devices contains a vulnerability that may lead to
a denial of service condition. An attacker may cause a denial of service
situation which leads to a restart of the webserver of the affected device.
The security vulnerability could be exploited by an attacker with network
access to the affected systems. Successful exploitation requires no system
privileges and no user interaction. An attacker could use the vulnerability
to compromise availability of the device.
