Loading vulnerability…
CVE-2020-29134 is a path traversal vulnerability in TOTVS Fluig Lake 1.7.0 and TOTVS Fluig 1.6.5 and 1.6.4. The platform inadequately restricts traversal sequences supplied through the base64-encoded file parameter, enabling requests to escape the intended file-access location.

This repository provides a Bash script (xfluig.sh) and documentation (README.md) for exploiting CVE-2020-29134, a path traversal vulnerability in the TOTVS Fluig platform. The exploit targets the /volume/stream/Rmx1aWc=/ HTTP endpoint, abusing a base64-encoded parameter to traverse directories and read arbitrary files from the server. The script automates payload generation for both Linux and Windows targets, focusing on extracting sensitive files such as domain.xml (which may contain database and LDAP credentials), /etc/passwd, and desktop.ini. The script supports both automated and manual modes, allowing the user to specify custom files to extract. The README provides clear usage instructions, affected versions, and example payloads. The exploit is operational and can be used to extract sensitive information from unpatched Fluig instances accessible over the network.
