Technical details

Multiple cross-site scripting (XSS) vulnerabilities exist in Zimbra Collaboration (formerly Zimbra Collaboration Suite) versions prior to 8.7.0. The flaws, tracked internally by Zimbra as bugs 103956, 103995, 104475, 104838, and 104839, stem from improper neutralization of user-supplied input during web page generation (CWE-79). A remote, unauthenticated attacker can exploit these vulnerabilities by sending a crafted request or email that, when viewed by a victim, executes arbitrary JavaScript or HTML in the context of the victim's browser session. This can lead to session hijacking, unauthorized data access, or phishing. The issues are resolved in Zimbra Collaboration 8.7.0.
