Horizon Alert
Summary of the vulnerability and why it matters
The web management interface of certain DrayTek routers is vulnerable due to a flaw in a specific function. This weakness allows for the injection of operating system commands, which could be exploited remotely. The potential impact includes unauthorized system control and data compromise.
- Vulnerable web management interface
- Allows OS command injection
- Potential for system control compromise
Attack Path
How an attacker could exploit the issue
An unauthenticated attacker can exploit this vulnerability by sending a specially crafted request to the affected web management interface. This request can lead to the execution of arbitrary operating system commands on the targeted device. The attacker can then potentially gain unauthorized control over the system, impacting its operations and data. Organizations using the affected devices are at risk if this vulnerability is exploited.
- Unauthenticated network access required.
- Attacker sends malicious request.
- OS command injection occurs.
