CVE-2021-34829 (GCVE-0-2021-34829)

Vulnerability from cvelistv5 – Published: 2021-07-15 17:35 – Updated: 2024-08-04 00:26

Summary

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-1330 1.13B01 BETA routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the HNAP_AUTH HTTP header. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-12065.
