CVE-2024-57022
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary operating system commands on TOTOLINK X5000R routers by injecting malicious commands through the sHour parameter in the setWiFiScheduleCfg function. Attackers can gain full control of affected devices, potentially compromising network security. Only users of specific TOTOLINK X5000R router versions are affected.
💻 Affected Systems
- TOTOLINK X5000R
📦 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 manipulation, credential theft, and use as attack platform against internal network.
If Mitigated
Limited impact with proper network segmentation, but still allows router compromise and potential internal network access.
🎯 Exploit Status
Exploitation requires authentication to router web interface; complexity is medium due to need for command injection knowledge.
