5.5

Medium

VectorAV:N/AC:L/Au:S/C:P/I:P/A:N
Name of the Vulnerable Software and Affected Versions Zimbra Collaboration (ZCS) versions 9.0 through 10.0
Description A reflected cross-site scripting (XSS) vulnerability has been identified in the Zimbra webmail admin interface. This vulnerability occurs due to inadequate input validation of the packages parameter, allowing an authenticated attacker to inject and execute arbitrary JavaScript code within the context of another user's browser session. By uploading a malicious JavaScript file and crafting a URL containing its location in the packages parameter, the attacker can exploit this vulnerability. Subsequently, when another user visits the crafted URL, the malicious JavaScript code is executed.
Recommendations For Zimbra Collaboration (ZCS) versions 9.0 through 10.0, consider disabling the vulnerable packages parameter in the webmail admin interface as a temporary workaround until a patch is available. Restrict access to the webmail admin interface to minimize the risk of exploitation. Avoid using the packages parameter in the affected API endpoint until the issue is resolved. Update to version 10.0.8 or later, as it includes security fixes for the identified vulnerabilities.
