AirLive BU-3026
AirLive MD-3025
AirLive WL-2000CAM
AirLive POE-200CAM v2

Versions: BU-2015 firmware 1.03.18 16.06.2014, BU-3026 firmware 1.43 21.08.2014, MD-3025 firmware 1.81 21.08.2014, WL-2000CAM firmware LM.1.6.18 14.10.2011, POE-200CAM v2 firmware LM.1.6.17.01

Operating Systems: Embedded Linux (Boa web server)

Default Config Vulnerable: ⚠️ Yes

Notes: All default configurations are vulnerable due to hard-coded credentials in the web server.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise allowing remote code execution, credential theft, and device takeover leading to network infiltration or data exfiltration.

🟠

Likely Case

Unauthorized access to device management interface leading to configuration changes, surveillance disruption, or credential harvesting.

🟢

If Mitigated

Limited impact if devices are behind firewalls with strict network segmentation and access controls.

🌐 Internet-Facing: HIGH - Directly accessible devices can be exploited remotely without authentication.

🏢 Internal Only: MEDIUM - Internal attackers or compromised internal systems could exploit this vulnerability.

🎯 Exploit Status

Public PoC: ⚠️ Yes

Weaponized: CONFIRMED

Unauthenticated Exploit: ⚠️ Yes

Complexity: LOW

Exploitation requires only HTTP requests to the vulnerable CGI endpoint. Public exploit code and detailed analysis are available.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown

Vendor Advisory: No official vendor advisory found

Restart Required: No

Instructions:

No official patch available. Consider upgrading to newer firmware versions if available from vendor, though specific patched versions are not documented.

🔧 Temporary Workarounds

Network Segmentation

all

Isolate affected devices in separate VLANs with strict firewall rules blocking external access to port 80/443.

Access Control Lists

all

Implement IP-based access control to restrict management interface access to authorized administrative networks only.

🧯 If You Can't Patch

Immediately remove affected devices from internet-facing networks and place behind firewalls with strict ingress/egress filtering.
Monitor network traffic to/from affected devices for suspicious HTTP requests to cgi-bin/mft/wireless_mft.cgi endpoint.

🔍 How to Verify

Check if Vulnerable:

Check device firmware version via web interface or console. Attempt HTTP GET/POST requests to http://device-ip/cgi-bin/mft/wireless_mft.cgi with crafted parameters to test for credential disclosure.

Check Version:

Check via web interface at http://device-ip/ or console connection. No universal CLI command available.

Verify Fix Applied:

Verify no hard-coded credentials exist in the CGI script by examining firmware or testing with exploit tools. Ensure newer firmware versions don't contain the vulnerable code.

📡 Detection & Monitoring

Log Indicators:

Unusual HTTP requests to cgi-bin/mft/wireless_mft.cgi
Multiple failed authentication attempts followed by successful access
Unexpected configuration changes

Network Indicators:

HTTP traffic to device management ports from unexpected sources
Patterns matching known exploit payloads in HTTP requests

SIEM Query:

source_ip=* AND dest_port=80 AND url_path="*cgi-bin/mft/wireless_mft.cgi*" AND (http_method="POST" OR http_method="GET")
