What is CVE-2020-35199?

Ignite Realtime Openfire version 4.6.0 is vulnerable to a stored cross-site scripting (XSS) issue that occurs in create-bookmark.jsp. This vulnerability allows an attacker to save malicious scripts within the group chat configuration. When these bookmarks are accessed by users, the scripts execute in their browsers, potentially leading to unauthorized actions and data exposure. Proper validation and sanitization of user inputs could mitigate this type of vulnerability to enhance overall application security.

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.
