AI-analyzed exploit summary This repository provides a detailed technical analysis of CVE-2020-8809, a vulnerability in Gurux GXDLMS Director involving insecure download mechanisms and path traversal, leading to remote code execution. It includes reproduction steps and mitigation advice.
Description
Gurux GXDLMS Director prior to 8.5.1905.1301 downloads updates to add-ins and OBIS code over an unencrypted HTTP connection. A man-in-the-middle attacker can prompt the user to download updates by modifying the contents of gurux.fi/obis/files.xml and gurux.fi/updates/updates.xml. Then, the attacker can modify the contents of downloaded files. In the case of add-ins (if the user is using those), this will lead to code execution. In case of OBIS codes (which the user is always using as they are needed to communicate with the energy meters), this can lead to code execution when combined with CVE-2020-8810.
