Summary

The D-Link DSL-3782 router is susceptible to a buffer overflow vulnerability in its diagnostics functionality. This flaw allows authenticated remote attackers to exploit the 'set Diagnostics_Entry' function by sending an HTTP request containing a lengthy Addr value. The attack can lead to arbitrary code execution, enabling attackers to gain unauthorized access to the device and potentially compromise the network environment. Users are urged to update their firmware to mitigate this risk.

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.
