CVE-2024-57011

8.8 HIGH

📋 TL;DR

This vulnerability allows remote attackers to execute arbitrary operating system commands on TOTOLINK X5000R routers by injecting malicious commands into the 'minute' parameter of the setScheduleCfg function. Attackers can gain full control of affected devices, potentially compromising network security. Only users running the specific vulnerable firmware version are affected.

Default Config Vulnerable: ⚠️ Yes
Notes: Affects the web management interface. Requires access to the vulnerable endpoint.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete device takeover leading to network compromise, data exfiltration, lateral movement to other devices, and persistent backdoor installation.

🟠

Likely Case

Router compromise allowing traffic interception, DNS hijacking, credential theft, and use as a pivot point for further attacks.

🟢

If Mitigated

Limited impact if device is behind firewall with restricted WAN access and proper network segmentation.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Proof of concept available on GitHub. Exploitation requires authentication to the web interface.

Prevent external access to web management interface

Restrict Access with Firewall

all

Block access to router management ports from untrusted networks

🧯 If You Can't Patch

  • Isolate router on separate VLAN with strict access controls
  • Implement network monitoring for suspicious command execution patterns

🔍 How to Verify

Check if Vulnerable:

Check firmware version in web interface under System Status > Firmware Version

Check Version:

Login to router web interface and navigate to System Status

Verify Fix Applied:

Confirm firmware version is newer than V9.1.0cu.2350_B20230313

📡 Detection & Monitoring

Log Indicators:

  • Unusual command execution in system logs
  • Multiple failed authentication attempts followed by successful login

Network Indicators:

  • Unexpected outbound connections from router
  • Traffic to known malicious IPs

SIEM Query:

source="router_logs" AND ("setScheduleCfg" OR "minute=" OR suspicious_command_patterns)
