Zimbra Collaboration Server < 8.8.15 P11 / 9.x < 9.0.0 P4 XSS

medium Nessus Plugin ID 142878

Synopsis

The remote web server contains a web application that is affected by an XSS vulnerability.

Description

According to its self-reported version number, Zimbra Collaboration Server is below 8.8.15 Patch 11, or 9.x prior to 9.0.0 Patch 4. It is, therefore, affected by a cross-site scripting (XSS) vulnerability in the Webmail component. An unauthenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session. The injected JavaScript is in the account name of a user's profile.
The injected code can be reflected and executed when changing an e-mail signature.

Note that Nessus does not identify patch level or components versions for the Synacor Zimbra Collaboration Suite. You will need to verify if the patch has been applied by executing the command 'zmcontrol -v' from the command line as the 'zimbra' user.

Solution

Upgrade to version 8.8.15 P11, 9.0.0 P4, or later.
