CVE-2023-30352
📋 TL;DR
This vulnerability allows attackers to access the RTSP video feed of Tenda CP3 IP cameras using a hard-coded default password. Anyone using the affected camera model with the vulnerable firmware version is at risk of unauthorized video surveillance.
💻 Affected Systems
- Tenda CP3 IP Camera
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of video surveillance system allowing attackers to monitor private spaces, potentially leading to physical security breaches, blackmail, or intelligence gathering.
Likely Case
Unauthorized access to live video feeds enabling privacy violations, reconnaissance of physical spaces, and potential integration into botnets for DDoS attacks.
If Mitigated
Limited impact if cameras are on isolated networks with proper segmentation and access controls preventing external connections.
🎯 Exploit Status
Exploitation requires only knowledge of the hard-coded password and network access to the camera's RTSP service.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Not available
Restart Required: No
Instructions:
No official patch available. Contact Tenda support for firmware updates or replacement options.
🔧 Temporary Workarounds
Network Segmentation
allIsolate cameras on separate VLANs with strict firewall rules preventing external access to RTSP port (default 554).
RTSP Authentication Proxy
linuxImplement a reverse proxy that adds authentication before allowing RTSP connections to cameras.
🧯 If You Can't Patch
- Physically disconnect cameras from networks and use only for local recording
- Replace affected cameras with models from vendors that support password changes
🔍 How to Verify
Check if Vulnerable:
Attempt to access RTSP feed using default credentials: rtsp://camera_ip:554/stream1 with username 'admin' and default password (check references for exact password).Check Version:
Check camera web interface or use nmap to identify firmware versionVerify Fix Applied:
Verify RTSP feed cannot be accessed with default credentials after implementing workarounds.📡 Detection & Monitoring
Log Indicators:
- Multiple failed RTSP authentication attempts followed by successful access
- Unusual RTSP stream requests from unexpected IP addresses
Network Indicators:
- RTSP traffic to/from unexpected external IPs
- Port 554 scans from unknown sources
