Summary

GNU Wget prior to version 1.18 is vulnerable to a security issue that permits remote servers to write to arbitrary files. This is achieved by redirecting an HTTP request to a maliciously crafted FTP resource. This vulnerability could potentially allow attackers to overwrite files on the affected systems, leading to unauthorized modifications and security breaches. It is crucial for users to update to the latest version of Wget 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.
