CVE-2024-57025
📋 TL;DR
This CVE describes an OS command injection vulnerability in TOTOLINK X5000R routers via the 'desc' parameter in the setWiFiScheduleCfg function. Attackers can execute arbitrary commands with router privileges, potentially compromising the device. Users of TOTOLINK X5000R routers with the vulnerable firmware are affected.
💻 Affected Systems
- TOTOLINK X5000R
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full router compromise allowing attacker to intercept traffic, modify configurations, install persistent backdoors, pivot to internal networks, or brick the device.
Likely Case
Router takeover enabling network traffic monitoring, DNS hijacking, credential theft, and lateral movement to connected devices.
If Mitigated
Limited impact if router is behind firewall with restricted WAN access and strong network segmentation.
🎯 Exploit Status
Exploit requires authentication to router web interface. Public proof-of-concept demonstrates command injection.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.totolink.net/
Restart Required: Yes
Instructions:
1. Check vendor website for firmware updates. 2. Download latest firmware. 3. Log into router admin interface. 4. Navigate to firmware upgrade section. 5. Upload new firmware file. 6. Wait for reboot.
🔧 Temporary Workarounds
Disable WiFi Schedule Feature
allRemove or disable the vulnerable setWiFiScheduleCfg functionality
Restrict Web Interface Access
linuxLimit access to router admin interface to trusted IP addresses only
iptables -A INPUT -p tcp --dport 80 -s TRUSTED_IP -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -s TRUSTED_IP -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j DROP
iptables -A INPUT -p tcp --dport 443 -j DROP
🧯 If You Can't Patch
- Isolate router on separate VLAN with strict firewall rules
- Implement network monitoring for suspicious command execution patterns
🔍 How to Verify
Check if Vulnerable:
Check router firmware version in admin interface. If version is V9.1.0cu.2350_B20230313 or earlier, device is vulnerable.Check Version:
Login to router web interface and check System Status or Firmware Version page.Verify Fix Applied:
Verify firmware version has been updated to a version later than V9.1.0cu.2350_B20230313.📡 Detection & Monitoring
Log Indicators:
- Unusual command execution in system logs
- Multiple failed authentication attempts followed by setWiFiScheduleCfg access
- Suspicious processes spawned from web interface
Network Indicators:
- Unusual outbound connections from router
- DNS queries to malicious domains from router
- Unexpected port scans originating from router
SIEM Query:
source="router_logs" AND ("setWiFiScheduleCfg" OR "desc=" AND ("|" OR ";" OR "$" OR "`"))
