CVE-2024-4315

9.1 CRITICAL

📋 TL;DR

CVE-2024-4315 is a Local File Inclusion vulnerability in parisneo/lollms version 9.5 that allows attackers to perform directory traversal attacks on Windows systems. Due to insufficient sanitization of Windows-style paths (backslash characters), attackers can read or delete arbitrary files on the filesystem. This affects Windows users running the vulnerable lollms software.

💻 Affected Systems

Products:
  • parisneo/lollms
Versions: Version 9.5 specifically (check commit history for other potentially affected versions)
Operating Systems: Windows
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects Windows systems due to the Windows-style path handling vulnerability. Linux/macOS systems are not vulnerable to this specific path traversal.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise through arbitrary file read/deletion, potentially leading to data theft, system destruction, or privilege escalation.

🟠

Likely Case

Unauthorized access to sensitive files (configuration files, credentials, user data) and potential denial of service through file deletion.

🟢

If Mitigated

Limited impact if proper file permissions and network controls restrict access to sensitive files and the application.

🌐 Internet-Facing: HIGH - If the application is exposed to the internet, attackers can exploit this remotely without authentication.
🏢 Internal Only: MEDIUM - Internal attackers or compromised systems could exploit this to escalate privileges or access sensitive data.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation is straightforward through endpoints like /personalities and /del_preset using path traversal sequences with backslashes.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Fixed in commit 95ad36eeffc6a6be3e3f35ed35a384d768f0ecf6 and later versions

Vendor Advisory: https://github.com/parisneo/lollms/commit/95ad36eeffc6a6be3e3f35ed35a384d768f0ecf6

Restart Required: Yes

Instructions:

1. Update to the latest version of lollms from the official repository. 2. Apply commit 95ad36eeffc6a6be3e3f35ed35a384d768f0ecf6. 3. Restart the lollms service/application.

🔧 Temporary Workarounds

Network Isolation

all

Restrict network access to the lollms application to trusted networks only

Use firewall rules to block external access to lollms ports

File Permission Restrictions

windows

Run lollms with minimal file system permissions to limit damage from exploitation

Create a dedicated low-privilege user for lollms service

🧯 If You Can't Patch

  • Disable or block access to vulnerable endpoints (/personalities, /del_preset) via web application firewall or reverse proxy rules
  • Migrate the application to Linux/macOS where this specific Windows path vulnerability does not apply

🔍 How to Verify

Check if Vulnerable:

Check if running lollms version 9.5 on Windows and test for path traversal using backslash sequences in affected endpoints

Check Version:

Check lollms version in application interface or configuration files

Verify Fix Applied:

Verify the commit hash includes 95ad36eeffc6a6be3e3f35ed35a384d768f0ecf6 and test that path traversal with backslashes no longer works

📡 Detection & Monitoring

Log Indicators:

  • Unusual file access patterns in application logs
  • Requests containing path traversal sequences with backslashes (..\, .\.\, etc.)
  • Access to sensitive system files through lollms endpoints

Network Indicators:

  • HTTP requests to /personalities or /del_preset with unusual parameters
  • Multiple failed file access attempts from single source

SIEM Query:

source="lollms_logs" AND (uri_path="/personalities" OR uri_path="/del_preset") AND (param CONTAINS "..\\" OR param CONTAINS ".\\.\\")
