TITLE

Siemens SICAM For SM-2558 Expansion module ETA4 Service operation interruption in firmware (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2016-007983

DESCRIPTION

An issue was discovered in Siemens ETA4 firmware (all versions prior to Revision 08) of the SM-2558 extension module for: SICAM AK, SICAM TM 1703, SICAM BC 1703, and SICAM AK 3. Specially crafted packets sent to Port 2404/TCP could cause the affected device to go into defect mode. A cold start might be required to recover the system, a Denial-of-Service Vulnerability. Siemens SICAM For SM-2558 Expansion module ETA4 Firmware disrupts service operation (DoS) There are vulnerabilities that are put into a state.Port crafted packets 2404/TCP Is sent to defect Mode and denial of service (DoS) There is a possibility of being put into a state. The Siemenssm-2558 and sm-2556 communication modules are Fast Ethernet communication interface units for LAN/WAN. A denial of service vulnerability exists in the Siemens SICAMRTU device. Remote attackers may exploit this issue to cause denial-of-service conditions, denying service to legitimate users. Siemens SICAM AK, etc. are all products of German Siemens (Siemens). Siemens SICAM AK is a power monitoring system. SICAM TM 1703 is an automation module for use in SICAM RTU remote terminal units
