Detailsinfo

A vulnerability has been found in parisneo lollms-webui up to 9.4 on Windows and classified as problematic. This vulnerability affects the function Path(path).is_absolute of the component Request Handler. The manipulation with an unknown input leads to a absolute path traversal vulnerability. The CWE definition for the vulnerability is CWE-36. 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. As an impact it is known to affect confidentiality. CVE summarizes:

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 advisory is available at huntr.com. This vulnerability was named CVE-2024-2548 since 03/15/2024. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1006 by the MITRE ATT&CK project.

Upgrading to version 9.5 eliminates this vulnerability. Applying the patch 49b0332e98d42dd5204dda53dee410b160106265 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
