TITLE

Mitsubishi Electric MELSEC-Q Series Ethernet Multiple vulnerabilities in interface module

Trust: 0.8

sources: JVNDB: JVNDB-2016-007661

DESCRIPTION

An issue was discovered in Mitsubishi Electric Automation MELSEC-Q series Ethernet interface modules QJ71E71-100, all versions, QJ71E71-B5, all versions, and QJ71E71-B2, all versions. The affected Ethernet interface module is connected to a MELSEC-Q PLC, which may allow a remote attacker to connect to the PLC via Port 5002/TCP and cause a denial of service, requiring the PLC to be reset to resume operation. This is caused by an Unrestricted Externally Accessible Lock. Using incomplete or dangerous encryption algorithms (CWE-327) - CVE-2016-8370 The password included in the communication data is encrypted with a weak encryption algorithm. Inappropriate restrictions on external operations (CWE-412) - CVE-2016-8368 Port by remote third party 5002/TCP via PLC Resulting in service disruption (DoS) There is a possibility of being attacked.A password may be obtained by a remote party or service operation may be interrupted (DoS) There is a possibility of being attacked. Mitsubishi Electric is a Japanese company. An attacker exploiting a vulnerability can result in a denial of service condition. Attackers can exploit these issues to perform unauthorized actions or cause denial-of-service conditions
