VAR-201802-1278
Vulnerability from variot - Updated: 2024-11-23 22:34In /usr/local/etc/config/addons/mh/loopupd.sh on eQ-3 AG HomeMatic CCU2 2.29.22 devices, software update packages are downloaded via the HTTP protocol, which does not provide any cryptographic protection of the downloaded contents. An attacker with a privileged network position (which could be obtained via DNS spoofing of www.meine-homematic.de or other approaches) can exploit this issue in order to provide arbitrary malicious firmware updates to the CCU2. This can result in a full system compromise. eQ-3 AG HomeMatic CCU2 The device contains cryptographic vulnerabilities.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. The eQ-3AGHomematicCCU2 is a central control unit for the German eQ-3 company that controls smart home devices. There is a security vulnerability in the /usr/local/etc/config/addons/mh/loopupd.sh file in the eQ-3 AG HomeMatic CCU2 version 2.29.22
