CVE-2023-25201
📋 TL;DR
This CVE describes a Cross-Site Request Forgery (CSRF) vulnerability in MultiTech Conduit AP MTCAP2-L4E1 devices running firmware v6.0.0. It allows remote attackers to upload malicious scripts and execute arbitrary code by tricking authenticated users into visiting specially crafted web pages. Organizations using these specific MultiTech access points with vulnerable firmware are affected.
💻 Affected Systems
- MultiTech Conduit AP MTCAP2-L4E1
- MultiTech Conduit AP MTCAP2-L4E1-868-042A
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise allowing attacker to execute arbitrary code, modify device configuration, establish persistence, and potentially pivot to internal networks.
Likely Case
Unauthorized script execution leading to device configuration changes, data exfiltration, or disruption of network services.
If Mitigated
Attack fails due to CSRF protections, proper network segmentation, or lack of authenticated user interaction.
🎯 Exploit Status
Exploitation requires tricking an authenticated user into visiting a malicious page. No public exploit code identified in references.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version after v6.0.0 (check vendor for specific fixed version)
Vendor Advisory: https://www.multitech.com
Restart Required: Yes
Instructions:
1. Check MultiTech website for security advisory. 2. Download latest firmware version. 3. Backup current configuration. 4. Upload and apply new firmware via web interface or CLI. 5. Verify successful update and restore configuration if needed.
🔧 Temporary Workarounds
Implement CSRF Tokens
allAdd anti-CSRF tokens to web interface forms if custom web interface exists
Custom implementation required - no standard commands
Network Segmentation
allIsolate MultiTech APs from critical networks and restrict web interface access
firewall rules to restrict access to AP management interface
🧯 If You Can't Patch
- Restrict web interface access to trusted IP addresses only using firewall rules
- Implement strict user access controls and require re-authentication for sensitive actions
🔍 How to Verify
Check if Vulnerable:
Check device firmware version via web interface (System > Status) or CLI command 'show version'Check Version:
show version (CLI) or check System Status in web interfaceVerify Fix Applied:
Confirm firmware version is updated beyond v6.0.0 and test CSRF protection on script upload functionality📡 Detection & Monitoring
Log Indicators:
- Unexpected script uploads
- Unauthorized configuration changes
- Multiple failed authentication attempts followed by successful upload
Network Indicators:
- Unusual outbound connections from AP
- HTTP POST requests to upload endpoints from unexpected sources
