Technical details
A stack-based buffer overflow vulnerability exists in the HNAP Service component of D-Link DCS-935L firmware (versions <= 1.10.01). The flaw is located in the SetDeviceSettings function within /web/cgi-bin/hnap/hnap_service. Specifically, the AESDecrypt function calls a conversion sub-function (sub_41B20C) that lacks length validation when processing the AdminPassword XML node. By sending a specially crafted, excessively long hexadecimal string in an XML request, a remote authenticated attacker can overflow a fixed-size stack buffer. This can lead to arbitrary remote code execution (RCE) with the privileges of the service. Public exploit code is available.
Affected products
- D-Link DCS-935L Firmware up to 1.10.01
