| Title | D-Link DIR-815 Firmware 1.01b14 Command Injection |
|---|
| Description | An authenticated command injection vulnerability exists in D-Link DIR-815 firmware version 1.01b14.
The CGI endpoint service.cgi resolves to the cgibin executable. The handler function servicecgi_main() retrieves user-controlled parameters such as EVENT and SERVICE from HTTP requests without sufficient sanitization or validation.
These parameters are directly passed to lxmldbc_system(), which constructs shell commands using vsnprintf() and executes them via system(). As a result, an authenticated attacker with administrative privileges may inject arbitrary operating system commands and achieve remote code execution on the device.
