Horizon Alert
Summary of the vulnerability and why it matters
This vulnerability affects TP-Link Archer AX21 firmware. The flaw allows an unauthenticated attacker to inject commands that run with root privileges. This could lead to unauthorized access and control over affected devices.
- Vulnerable web management interface
- Unsanitized command injection
- System compromise and unauthorized access
Attack Path
How an attacker could exploit the issue
This vulnerability in TP-Link Archer AX21 routers could allow an unauthenticated attacker to execute commands with root privileges. The attack leverages a command injection flaw within the web management interface. By sending a specially crafted POST request, an attacker can inject and run arbitrary commands on the affected device. This could lead to a compromise of the device and potentially impact the network it manages.
- Web interface is exposed.
- Attacker sends a POST request.
- Commands execute as root.
Live Threat
Current exploitation, exposure, and threat context
