CVE-2024-6040
📋 TL;DR
This vulnerability in parisneo/lollms-webui allows attackers to perform Cross-Site Request Forgery (CSRF) attacks against binding management endpoints. Attackers can trick authenticated users into executing unauthorized actions like installing, uninstalling, or modifying bindings on their local machine. Users running version v9.8 of the web interface are affected.
💻 Affected Systems
- parisneo/lollms-webui
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could install malicious bindings that execute arbitrary code on the victim's machine, potentially leading to full system compromise, data theft, or ransomware deployment.
Likely Case
Attackers trick users into visiting malicious websites that silently trigger binding management actions, potentially disrupting the application or installing unwanted components.
If Mitigated
With proper CSRF protections and network segmentation, impact is limited to binding management functions without system-level compromise.
🎯 Exploit Status
Exploitation requires user interaction (visiting malicious site) but uses standard CSRF techniques. The vulnerability is well-documented in the bounty report.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: v9.9 or later
Vendor Advisory: https://huntr.com/bounties/ac0bbb1d-89aa-42ba-bc48-1b59bd16acc7
Restart Required: Yes
Instructions:
1. Update to lollms-webui version v9.9 or later. 2. Restart the lollms-webui service. 3. Verify the client_id parameter is present in lollms_binding_infos.
🔧 Temporary Workarounds
Disable Binding Management Endpoints
allTemporarily disable the vulnerable endpoints until patching is possible.
Modify configuration to disable /reload_binding, /install_binding, /reinstall_binding, /unInstall_binding, /set_active_binding_settings, and /update_binding_settings endpoints
Implement CSRF Tokens Manually
allAdd CSRF protection to the affected endpoints by implementing proper token validation.
Add CSRF token generation and validation to the binding management endpoints in the source code
🧯 If You Can't Patch
- Restrict network access to the web interface to trusted IPs only using firewall rules.
- Run the application in a sandboxed environment with limited permissions to contain potential damage.
🔍 How to Verify
Check if Vulnerable:
Check if lollms_binding_infos configuration lacks client_id parameter and if version is v9.8.Check Version:
Check the application version in the web interface or configuration files.Verify Fix Applied:
Verify lollms_binding_infos includes client_id parameter and version is v9.9 or later.📡 Detection & Monitoring
Log Indicators:
- Unauthorized binding installation/uninstallation requests
- CSRF token validation failures
- Requests to binding management endpoints from unexpected sources
Network Indicators:
- HTTP POST requests to /reload_binding, /install_binding, /reinstall_binding, /unInstall_binding, /set_active_binding_settings, or /update_binding_settings without proper referrer headers
