D-Link COVR-2600R FW101b05 is vulnerable to Buffer Overflow. In the function sub_24E28, the HTTP_REFERER is obtained through an environment variable, and this field is controllable, allowing it to be used as the value for src.
This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-2020 v1.01rc001 Wi-Fi access points. Authentication is not required to exploit this vulnerability. The specific flaw exists within the processing of CGI scripts. When parsing the getpage parameter, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-10932.
