Summary

A command injection vulnerability exists in D-Link DIR-806 devices, specifically within the hnap_main function. This flaw arises because the function calls the system() command without proper validation of user-controlled parameters. Exploiting this vulnerability, remote attackers can execute arbitrary shell commands by manipulating specific HTTP headers. The absence of robust input validation and sanitization exposes the affected devices to significant security risks, allowing unauthorized access and control over the device.
