What is CVE-2020-35713?

The Belkin LINKSYS RE6500 router is susceptible to a remote command execution vulnerability that allows unauthenticated attackers to execute arbitrary commands. This can be achieved by exploiting shell metacharacters on the goform/setSysAdm page, also enabling them to set a new administrative password without proper authorization. Users of LINKSYS RE6500 devices should upgrade to firmware version 1.0.012.001 or later to mitigate this security issue.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
