What is CVE-2019-6487?

Certain TP-Link WDR Series devices, particularly through firmware version 3, are susceptible to a command injection vulnerability that may allow an authenticated attacker to execute arbitrary commands on the device. This occurs due to the inappropriate handling of shell metacharacters in the 'get_weather_observe citycode' field. By exploiting this flaw, attackers could potentially gain unauthorized access, compromising the security of the affected devices and the network they operate within.

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.
