What is CVE-2019-12562?

This vulnerability allows remote attackers to inject malicious scripts into the admin notification page of DotNetNuke versions prior to 9.4.0. When an administrator visits the compromised notification page, the embedded script executes, enabling attackers to perform administrative actions such as managing content, adding users, or uploading unauthorized files to the server. The exploit serves as a serious security breach, as it bypasses typical security measures and can lead to significant data manipulation and system compromise.

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.
