Exploited by Malware: True

Synopsis

The version of Atlassian Crowd installed on the remote host is affected by an remote code execution (RCE) vulnerability.

Description

The version of Atlassian Crowd installed on the remote host is 2.1.x prior to 3.0.5, 3.1.x prior to 3.1.6, 3.2.x prior to 3.2.8, 3.3.x prior to 3.3.5 or 3.4.x prior to 3.4.4. It is, therefore, affected by a remote code execution (RCE) vulnerability. An unauthenticated, remote attacker can exploit this, by using pdkinstall development plugin, to install arbitrary plugins, which permits remote code execution.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to version 3.0.5, 3.1.6, 3.2.8, 3.3.5, 3.4.4 or later.
