Details

CVE-2024-4320 describes a vulnerability in the parisneo/lollms software, specifically within the ExtensionBuilder().build_extension() function. The vulnerability arises from the /mount_extension endpoint, where a path traversal issue allows attackers to navigate beyond the intended directory structure. This is facilitated by the data.category and data.folder parameters accepting empty strings (""), which, due to inadequate input sanitization, can lead to the construction of a package_path that points to the root directory. Consequently, if an attacker can create a config.yaml file in a controllable path, this path can be appended to the extensions list and trigger the execution of __init__.py in the current directory, leading to remote code execution. The vulnerability affects versions from 5.9.0, and has been addressed in version 9.5.1.
