CVE-2023-30013
📋 TL;DR
This CVE describes a command injection vulnerability in TOTOLINK X5000R routers that allows remote attackers to execute arbitrary commands via the 'command' parameter in the setTracerouteCfg endpoint. Attackers can gain full control of affected routers without authentication. Users of TOTOLINK X5000R routers with vulnerable firmware versions are affected.
💻 Affected Systems
- TOTOLINK X5000R Wireless Router
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete router compromise allowing attacker to intercept all network traffic, install persistent backdoors, pivot to internal networks, and use router as botnet node.
Likely Case
Router takeover leading to DNS hijacking, credential theft from network traffic, and installation of malware on connected devices.
If Mitigated
Limited impact if router is behind firewall with restricted WAN access and proper network segmentation.
🎯 Exploit Status
Public exploit code available on GitHub and Packet Storm. Exploitation requires only HTTP POST request to vulnerable endpoint.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: No vendor advisory found
Restart Required: No
Instructions:
No official patch available. Check TOTOLINK website for firmware updates. If update exists, download from official site and flash via router admin interface.
🔧 Temporary Workarounds
Network Isolation
allPlace router behind firewall with strict inbound rules, blocking all WAN access to router admin interface.
Access Restriction
allConfigure firewall to only allow router management from specific trusted IP addresses.
🧯 If You Can't Patch
- Replace affected routers with different models from vendors with better security track record
- Implement strict network segmentation to isolate router management interface from production networks
🔍 How to Verify
Check if Vulnerable:
Check router firmware version via admin interface. If version matches affected versions, assume vulnerable.Check Version:
Login to router admin interface and check System Status or Firmware Update section for version information.Verify Fix Applied:
Test by attempting exploitation with known payloads (in controlled environment) or verify firmware version is updated to non-vulnerable release.📡 Detection & Monitoring
Log Indicators:
- HTTP POST requests to /cgi-bin/setting/setTracerouteCfg with command parameter containing shell metacharacters
- Unusual command execution in router logs
- Multiple failed login attempts followed by successful command injection
Network Indicators:
- HTTP traffic to router on non-standard ports containing shell commands
- Outbound connections from router to suspicious IPs
- DNS queries to malicious domains from router
SIEM Query:
source="router_logs" AND (uri="/cgi-bin/setting/setTracerouteCfg" OR "command=*;*" OR "command=*|*" OR "command=*`*" OR "command=*$(*")🔗 References
