What is CVE-2018-6518?

Composr CMS version 10.0.13 is vulnerable to a Cross-Site Scripting (XSS) attack. Specifically, an issue exists in the administration setup wizard where the 'site_name' parameter can be exploited through a crafted request to the '/adminzone/index.php' endpoint. This flaw allows attackers to inject malicious scripts into web pages viewed by other users, potentially leading to unauthorized access and data compromise. Proper input validation and encoding mechanisms are recommended to mitigate this vulnerability.

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.
