Synopsis

The remote Atlassian Confluence host is missing a security update.

Description

The version of Atlassian Confluence installed on the remote host is prior to 7.4.x < 7.4.17 / 7.13.x < 7.13.7 / 7.14.x < 7.14.3 / 7.15.x < 7.15.2 / 7.16.x < 7.16.4 / 7.17.x < 7.17.4 / 7.18.x < 7.18.1. It is, therefore, affected by a vulnerability as referenced in the CONFSERVER-79017 advisory.

- *Summary* A remote attacker who can connect to the Hazelcast service, running on port 5801 (and potentially 5701), is able to execute arbitrary code on all the nodes in a Confluence Data Center through Java deserialization. *Vulnerability Details* Confluence Data Center uses the third-party software Hazelcast, which is vulnerable to Java deserialization attacks (CVE-2016-10750). Hazelcast provides functionality needed to run Confluence Data Center as a cluster. A remote, unauthenticated attacker can exploit this vulnerability by sending a specially crafted JoinRequest, resulting in arbitrary code execution. The affected versions are from 1.3.0 before 7.4.17, from 7.13.0 before 7.13.7, from 7.14.0 before 7.14.3, from 7.15.0 before 7.15.2, from 7.16.0 before 7.16.4, from 7.17.0 before 7.17.4, and from 7.18.0 before 7.18.1. (atlassian-CONFSERVER-79017)

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 7.4.17, 7.13.7, 7.14.3, 7.15.2, 7.16.4, 7.17.4, 7.18.1 or later.
