What is CVE-2020-17453?

The WSO2 Management Console prior to version 5.10 is susceptible to a Cross-Site Scripting (XSS) attack. This vulnerability arises due to insufficient validation of the 'msgId' parameter in the carbon/admin/login.jsp file. An attacker can exploit this flaw to inject malicious scripts into the web interface, potentially compromising sensitive user session data and executing malicious code in the context of the user's session.

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.
