CVE-2024-4498
📋 TL;DR
This CVE describes a Path Traversal and Remote File Inclusion vulnerability in the parisneo/lollms-webui application that allows attackers to manipulate file paths and include arbitrary files. Successful exploitation leads to remote code execution on affected systems. Users running versions v9.7 through the latest are vulnerable.
💻 Affected Systems
- parisneo/lollms-webui
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise via remote code execution, allowing attackers to execute arbitrary commands, steal data, install malware, or pivot to other systems.
Likely Case
Unauthorized file access, data exfiltration, and potential system takeover through uploaded malicious payloads.
If Mitigated
Limited impact with proper input validation and file system restrictions in place.
🎯 Exploit Status
Exploitation involves manipulating the discussion_db_name parameter and bypassing existing input filters in multiple endpoints.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check latest release or commit after vulnerability disclosure
Vendor Advisory: https://huntr.com/bounties/9238e88a-a6ca-4915-9b5d-6cdb4148d3f4
Restart Required: Yes
Instructions:
Update to the latest patched version of lollms-webui
Follow the vendor's security advisory for specific patching steps
Restart the application after updating
🔧 Temporary Workarounds
Input Validation Enhancement
allImplement strict input validation for file path parameters
Modify /apply_settings function to validate discussion_db_name parameter
Update sanitize_path_from_endpoint() to properly filter path traversal sequences
Network Access Restriction
allRestrict network access to the vulnerable endpoints
Configure firewall rules to limit access to trusted IPs only
Use reverse proxy with request filtering
🧯 If You Can't Patch
- Implement web application firewall (WAF) rules to block path traversal patterns
- Isolate the vulnerable system in a restricted network segment
🔍 How to Verify
Check if Vulnerable:
Check if running lollms-webui version v9.7 or later and examine if the vulnerable endpoints are accessibleCheck Version:
Check the application version in the web interface or configuration filesVerify Fix Applied:
Verify the application version is updated beyond the vulnerable range and test the affected endpoints with path traversal attempts📡 Detection & Monitoring
Log Indicators:
- Unusual file path patterns in requests to /apply_settings endpoint
- Multiple failed attempts to access restricted directories
- Unexpected file inclusion or execution logs
Network Indicators:
- HTTP requests containing path traversal sequences (../, ..\)
- Requests to binding installation endpoints with unusual parameters
SIEM Query:
source="web_server" AND (uri="/apply_settings" OR uri CONTAINS "binding") AND (param CONTAINS "../" OR param CONTAINS "..\")
