Technical details

Multiple cross-site scripting (XSS) vulnerabilities exist in Zimbra Collaboration Suite (ZCS) versions prior to 8.7.0. The vulnerabilities, tracked internally by Zimbra as bugs 104222, 104910, 105071, and 105175, stem from improper neutralization of user-supplied input during web page generation. A remote, unauthenticated attacker can exploit these flaws by persuading a user to visit a malicious URL or interact with crafted content. Successful exploitation allows the execution of arbitrary JavaScript in the context of the victim's browser session, potentially leading to session hijacking, credential theft, or unauthorized administrative actions. The issues are resolved in Zimbra Collaboration 8.7.0 GA.
