CVE-2022-47374
Estado: ModificadaAlta (7.5)—
A vulnerability has been identified in SIMATIC 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.
CVSS
- Versión: 3.1
