CVE-2024-2366
📋 TL;DR
This CVE describes a remote code execution vulnerability in the parisneo/lollms-webui application. Attackers can exploit insufficient path sanitization in the reinstall_binding functionality to upload malicious Python files and execute arbitrary code on the server. All users running the latest version of lollms-webui are affected.
💻 Affected Systems
- parisneo/lollms-webui
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete server compromise allowing attacker to install backdoors, steal data, pivot to internal networks, or deploy ransomware.
Likely Case
Attacker gains shell access to the server, potentially compromising the entire application and underlying system.
If Mitigated
If proper network segmentation and least privilege are implemented, impact may be limited to the application container or service account.
🎯 Exploit Status
Exploitation requires access to the web interface but path traversal and file upload are straightforward.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check latest GitHub release
Vendor Advisory: https://github.com/parisneo/lollms-webui/security/advisories
Restart Required: Yes
Instructions:
1. Update to the latest patched version from GitHub. 2. Restart the lollms-webui service. 3. Verify the fix by checking the binding_path sanitization in the code.
🔧 Temporary Workarounds
Disable reinstall_binding endpoint
allRemove or disable the vulnerable endpoint in the application configuration.
Modify lollms_core/lollms/server/endpoints/lollms_binding_infos.py to comment out or remove the reinstall_binding function
Implement WAF rules
allAdd web application firewall rules to block path traversal patterns.
Add WAF rule: deny requests containing '../' or similar path traversal sequences
🧯 If You Can't Patch
- Network segmentation: Isolate lollms-webui from critical systems and restrict inbound access.
- Implement strict file upload validation and path sanitization at the application level.
🔍 How to Verify
Check if Vulnerable:
Check if your version contains the vulnerable reinstall_binding function without proper path sanitization in lollms_core/lollms/server/endpoints/lollms_binding_infos.py.Check Version:
Check the GitHub repository or application version file for current version.Verify Fix Applied:
Verify that path traversal attempts are blocked and binding_path is properly sanitized in the updated code.📡 Detection & Monitoring
Log Indicators:
- Unusual file uploads to binding directories
- Path traversal patterns in requests
- Execution of unexpected Python files
Network Indicators:
- HTTP requests to reinstall_binding endpoint with suspicious parameters
SIEM Query:
