| Title | D-Link DI-8100 16.07.26A1 Denial of Service |
|---|
| Description | The yyxz.asp endpoint contains an insecure call to the sprintf function. When processing the user-supplied id parameter, the application fails to perform any length validation or input sanitization. It concatenates the user-controlled string with a fixed prefix and writes the result into a small stack buffer, leading to a classic buffer overflow condition. |
