DescriptionNVD

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link AC1750 prior to 1.1.4 Build 20211022 rel.59103(5553) routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the NetUSB.ko module. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-15835.
