CVE-2024-2356
📋 TL;DR
This CVE describes a Local File Inclusion vulnerability in the lollms-webui application that allows attackers to execute arbitrary Python code remotely. The vulnerability affects all users running the latest version of parisneo/lollms-webui when exposed externally, potentially leading to full system compromise.
💻 Affected Systems
- parisneo/lollms-webui
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover via remote code execution, allowing attackers to install malware, exfiltrate data, or create persistent backdoors.
Likely Case
Attackers gain shell access to the server, enabling data theft, lateral movement, or cryptocurrency mining operations.
If Mitigated
Limited impact if proper network segmentation and access controls prevent external exploitation.
🎯 Exploit Status
Exploitation requires no authentication and has simple payload structure. Public exploit details available in bounty report.

Restart Required: Yes
Instructions:
1. Update to latest lollms-webui version. 2. Apply commit 41dbb1b3f2e78ea276e5269544e50514252c0c25. 3. Restart the lollms-webui service.
🔧 Temporary Workarounds
Network Restriction
linuxRestrict access to lollms-webui to trusted IP addresses only
iptables -A INPUT -p tcp --dport [lollms-port] -s [trusted-ip] -j ACCEPT
iptables -A INPUT -p tcp --dport [lollms-port] -j DROP
Endpoint Disablement
allDisable the vulnerable /reinstall_extension endpoint
Comment out or remove the @router.post("/reinstall_extension") route in the source code
🧯 If You Can't Patch
- Immediately restrict network access to localhost only (bind to 127.0.0.1 instead of 0.0.0.0)
- Implement Web Application Firewall (WAF) rules to block requests containing path traversal patterns
🔍 How to Verify
Check if Vulnerable:
Check if /reinstall_extension endpoint exists and accepts name parameter without proper validationCheck Version:
git log --oneline -1Verify Fix Applied:
Verify commit 41dbb1b3f2e78ea276e5269544e50514252c0c25 is applied and test LFI payloads are rejected📡 Detection & Monitoring
Log Indicators:
- POST requests to /reinstall_extension with suspicious name parameters
- Python import errors from unexpected file paths
- Unusual process execution from lollms-webui context
Network Indicators:
- HTTP requests with path traversal sequences (../) in parameters
- Unexpected outbound connections from lollms-webui server
SIEM Query:
source="web_logs" AND uri_path="/reinstall_extension" AND (param_name="name" AND param_value MATCHES "\.\.\/")
