SIEMENS SIMATIC CP 1543-1 Device Denial of Service Vulnerability

Trust: 0.8

sources: IVD: fe6b4ae9-2ba1-4c21-af48-55d5ed245b66 // CNVD: CNVD-2016-11368

DESCRIPTION

A vulnerability has been identified in SIMATIC CP 1543-1 (All versions < V2.0.28), SIPLUS NET CP 1543-1 (All versions < V2.0.28). Under special conditions it was possible to write SNMP variables on port 161/udp which should be read-only and should only be configured with TIA-Portal. A write to these variables could reduce the availability or cause a denial-of-service. Siemens SIMATIC CP 1543-1 Is SNMPv3 Write access or SNMPv1 Service operation disruption when is enabled (DoS) There are vulnerabilities that are put into a state.By a remotely authenticated user SNMP Service operation disruption by changing variables (DoS) There is a possibility of being put into a state. SIEMENSSIMATICCP1543-1 is a communication processor that integrates security functions such as firewall, VPN, security protocol, data encryption, etc. It provides network connection and secure communication of s7-1500 controller. A denial of service vulnerability exists in the SIEMENSSIMATICCP1543-1 device. When SNMPv3 write access or SNMPv1 is turned on, an attacker exploits vulnerabilities to modify SNMP variables through the 161/udp port, thereby reducing availability or causing denial of service attacks. Siemens SIMATIC CP 1543-1 is prone to a privilege-escalation vulnerability and a denial-of-service vulnerability. Attackers can leverage these issues to gain elevated privileges and cause denial-of-service conditions on the affected device. Siemens SIMATIC CP 1543-1 is a controller of Germany's Siemens (Siemens) company that is used to connect communication processors to Ethernet and provides integrated security functions
