Vulnerability from variot
A vulnerability has been identified in RUGGEDCOM RM1224 (V6.3), SCALANCE M-800 (V6.3), SCALANCE S615 (V6.3), SCALANCE SC-600 (All Versions >= V2.1 and < V2.1.3). Multiple failed SSH authentication attempts could trigger a temporary Denial-of-Service under certain conditions. When triggered, the device will reboot automatically. plural Siemens The product is vulnerable to improper restrictions on excessive authentication attempts.Denial of service (DoS) It may be put into a state. SCALANCE SC-600 devices (SC622-2C, SC632-2C, SC636-2C, SC642-2C, SC646-2C) are used to protect trusted industrial networks from attacks from untrusted networks. SCALANCE M-800/S615 industrial routers are used for secure remote access to the factory through mobilenetworks (such as GPRS or UMTS). It has an integrated security function of firewall to prevent unauthorized access, and VPN can protect data transmission. RUGGEDCOM RM1224 is a 4G router for wireless IP communication from Ethernet-based devices via LTE (4G)-mobile radio.
Siemens SCALANCE and RUGGEDCOM devices have a denial of service vulnerability. An attacker can use the vulnerability to trigger a temporary denial of service
