Zimbra Collaboration Server < 8.8.15 P10 / 9.x < 9.0.0 P3 Unrestricted Upload

high Nessus Plugin ID 142892

Language:

Synopsis

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

Description

According to its self-reported version number, Zimbra Collaboration Server is below 8.8.15 Patch 10, or 9.x prior to 9.0.0 Patch 3. It is, therefore, affected by an unrestricted upload vulnerability in the '/service/upload' servlet. An authenticated, remote attacker can exploit this, by uploading executable files in the Contact section of the mailbox as an avatar image for a contact, to upload and store files in '/opt/zimbra/data/tmp/upload/', leaving it open to possible remote execution.

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 P10, 9.0.0 P3, or later.
