CVE-2015-3036
SEC Consult has found a remote code execution vulnerability in the NetUSB Linux kernel module made by Kcodes.
Potentially millions of routers are at risk.
Kcodes is : “The world’s premier technology provider of mobile printing, audio and video communication, file sharing, and USB applications for iPhones, iPads, smart phones and tablets (Android and Windows), MacBooks, and Ultrabooks.”
Details
NetUSB suffers from a remotely exploitable kernel stack buffer overflow. Because of insufficient input validation, an overly long computer name can be used to overflow the “computer name” kernel stack buffer. This results in memory corruption which can be turned into arbitrary remote code execution.
The SEC Consult advisory noted :
The vulnerability has been verified to exist in most recent firmware versions of the following devices:
TP-Link TL-WDR4300 V1
TP-Link WR1043ND v2
NETGEAR WNDR4500
