Atlassian Confluence < 6.13.23 / 6.14 < 7.4.11 / 7.5 < 7.11.6 / 7.12 < 7.12.5 Webwork OGNL Injection (CONFSERVER-67940)

critical Nessus Plugin ID 152864

Synopsis

A web application running on the remote host is affected by an OGNL injection vulnerability

Description

According to its self-reported version number, the Atlassian Confluence application running on the remote host is prior to 6.13.23, 6.14.x prior to 7.4.11, 7.5.x prior to 7.11.6 or 7.12.x prior to 7.12.5. It is, therefore, affected by an OGNL injection vulnerability that would allow an authenticated user, and in some instances an unauthenticated user, to execute arbitrary code on a Confluence Server or Data Center instance.

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 Atlassian Confluence version 6.13.23, 7.4.11, 7.11.6, 7.12.5 or later.
