CVE-2025-29046
📋 TL;DR
A buffer overflow vulnerability in ALFA WiFi CampPro router firmware allows remote attackers to execute arbitrary code by sending specially crafted GAPSMinute3 key values. This affects ALFA WiFi CampPro router users running vulnerable firmware versions. Successful exploitation could lead to complete device compromise.
💻 Affected Systems
- ALFA WiFi CampPro router
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote attacker gains full control of the router, enabling traffic interception, credential theft, lateral movement into connected networks, and persistent backdoor installation.
Likely Case
Router compromise leading to network traffic monitoring, DNS hijacking, credential harvesting, and potential pivot point for attacking connected devices.
If Mitigated
With proper network segmentation and access controls, impact limited to isolated router device without lateral movement capabilities.
🎯 Exploit Status
Public proof-of-concept code available on GitHub demonstrates remote code execution without authentication.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: Yes
Instructions:
1. Check vendor website for firmware updates
2. Download latest firmware if available
3. Upload firmware via router admin interface
4. Reboot router after update
🔧 Temporary Workarounds
Disable remote management
allDisable WAN-side management interface to prevent external exploitation
Network segmentation
allIsolate router on separate VLAN with strict firewall rules
🧯 If You Can't Patch
- Replace vulnerable router with supported model
- Implement strict network access controls and monitor for exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check router firmware version via admin interface. If version is ALFA_CAMPRO-co-2.29, device is vulnerable.Check Version:
Check router web interface or use nmap/router scanning toolsVerify Fix Applied:
Verify firmware version has been updated to a version newer than ALFA_CAMPRO-co-2.29📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to router management interface
- Multiple failed exploitation attempts
- Unexpected router reboots or configuration changes
Network Indicators:
- Unusual outbound connections from router
- DNS queries to suspicious domains
- Traffic redirection patterns
SIEM Query:
source_ip=router_ip AND (uri_path CONTAINS "GAPSMinute3" OR method=POST AND status_code=500)
