A path traversal vulnerability exists in the parisneo/lollms-webui application, specifically within the `lollms_core/lollms/server/endpoints/lollms_binding_files_server.py` and `lollms_core/lollms/security.py` files. Due to inadequate validation of file paths between Windows and Linux environments using `Path(path).is_absolute()`, attackers can exploit this flaw to read any file on the system. This issue affects the latest version of LoLLMs running on the Windows platform. The vulnerability is triggered when an attacker sends a specially crafted request to the `/user_infos/{path:path}` endpoint, allowing the reading of arbitrary files, as demonstrated with the `win.ini` file. The issue has been addressed in version 9.5 of the software.
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize absolute path sequences such as "/abs/path" that can resolve to a location that is outside of that directory.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
