CVE-2020-10881

Estado: ModificadaCrítica (9.8)—

This vulnerability allows remote attackers to execute arbitrary code on affected installations of TP-Link Archer A7 Firmware Ver: 190726 AC1750 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 the root user. Was ZDI-CAN-9660.
