CVE intelligence and bounded remediation
CVE-2024-9920 — Lollms Lollms Web Ui security vulnerability
In version v12 of parisneo/lollms-webui, the 'Send file to AL' function allows uploading files with various extensions, including potentially dangerous ones like .py, .sh, .bat, and more. Attackers can exploit this by uploading files with malicious content and then using the '/open_file' API endpoint to execute these files. The vulnerability arises from the use of 'subprocess.Popen' to open files without proper validation, leading to potential remote code execution.

Matched remediation archetype
Path traversal, unsafe upload, and file handling
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
- Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
- Review canonicalization and containment checks across supported operating systems and storage backends.
Remediate safely
- Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
- Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
- Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
