Description

parisneo/lollms version 9.5 is vulnerable to Local File Inclusion (LFI) attacks due to insufficient path sanitization. The sanitize_path_from_endpoint function fails to properly sanitize Windows-style paths (backward slash \), allowing attackers to perform directory traversal attacks on Windows systems. This vulnerability can be exploited through various routes, including personalities and /del_preset, to read or delete any file on the Windows filesystem, compromising the system's availability.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for lollms, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update lollms to 9.5.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-4315 is resolved across your whole dependency graph.

  3. Workarounds

    Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.
