Technical details

A cross-site scripting (XSS) vulnerability exists in Zimbra Collaboration (formerly Zimbra Collaboration Suite) in versions prior to 8.7.0. The flaw allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, identified internally by Zimbra as bug 102637. The vulnerability is network-reachable and requires some level of user interaction (UI:R), such as a user clicking a malicious link or viewing a crafted email. Successful exploitation allows an attacker to execute code in the context of the victim's browser session, which can lead to information disclosure or session hijacking. The issue was addressed in the Zimbra Collaboration 8.7.0 GA release.
