CVE-2021-35003

This vulnerability allows remote attackers to execute arbitrary code on affected installations of TP-Link Archer C90 1.0.6 Build 20200114 rel.73164(5553) routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of DNS responses. A crafted DNS message can trigger an overflow of a fixed-length, stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-14655.
