CVE-2024-57013
📋 TL;DR
This CVE describes an OS command injection vulnerability in TOTOLINK X5000R routers where attackers can execute arbitrary commands via the 'switch' parameter in the setScheduleCfg function. This allows remote code execution with the privileges of the web interface service. All users of affected TOTOLINK X5000R router versions are vulnerable.

- TOTOLINK X5000R
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the router allowing attackers to install persistent backdoors, intercept network traffic, pivot to internal networks, or use the device for botnet activities.
Likely Case
Attackers gain shell access to the router, modify configurations, steal credentials, or use the device as a foothold for further network attacks.
If Mitigated
If proper network segmentation and access controls are in place, impact may be limited to the router itself without lateral movement.
🎯 Exploit Status
Exploitation requires access to the web interface, though authentication status is unclear from available information.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor for latest firmware version
