Last modified

CVE-2024-2356 is a critical-severity vulnerability rated 9.6/10 on the CVSS scale. A Local File Inclusion (LFI) vulnerability exists in the '/reinstall_extension' endpoint of the parisneo/lollms-webui application, specifically within the `name` parameter of the `@router.post("/reinstall_extension")` route. This vulnerability allows attackers to inject a malicious `name` parameter, leading to the server loading and executing arbitrary Python files from the upload directory for discussions. EPSS estimates a 0.77% chance of exploitation in the next 30 days.

Description

A Local File Inclusion (LFI) vulnerability exists in the '/reinstall_extension' endpoint of the parisneo/lollms-webui application, specifically within the `name` parameter of the `@router.post("/reinstall_extension")` route. This vulnerability allows attackers to inject a malicious `name` parameter, leading to the server loading and executing arbitrary Python files from the upload directory for discussions. This issue arises due to the concatenation of `data.name` directly with `lollmsElfServer.lollms_paths.extensions_zoo_path` and its use as an argument for `ExtensionBuilder().build_extension()`. The server's handling of the `__init__.py` file in arbitrary locations, facilitated by `importlib.machinery.SourceFileLoader`, enables the execution of arbitrary code, such as command execution or creating a reverse-shell connection. This vulnerability affects the latest version of parisneo/lollms-webui and can lead to Remote Code Execution (RCE) when the application is exposed to an external endpoint or the UI, especially when bound to `0.0.0.0` or in `headless mode`. No user interaction is required for exploitation.
