Technical details

A reflected cross-site scripting (XSS) vulnerability exists in the Zimbra Collaboration web interface, specifically within the /h/changepass endpoint. The vulnerability is caused by improper neutralization of user-supplied input in the 'skin' parameter, which is reflected back into the HTML response without adequate sanitization. An unauthenticated remote attacker can exploit this by tricking a user into clicking a malicious URL containing a JavaScript payload. Successful exploitation allows the attacker to execute arbitrary code in the context of the victim's browser session, potentially leading to session token theft or unauthorized administrative actions. This issue was addressed in Zimbra Collaboration version 8.7.0.
