The vulnerability of the sub_420F04() function in D-Link router microprogramming devices such as DWR-M920, DWR-M921, DWR-M960, DWR-M961, and DIR-825M allows a hacker to execute arbitrary code.

The vulnerability of the sub420F04 function in D-Link router microprogramming systems such as DWR-M920, DWR-M921, DWR-M960, DWR-M961, and DIR-825M lies in the copying of buffers without checking the size of the input data. Exploiting this vulnerability allows an attacker to execute arbitrary code...
