Atlassian Confluence 9.2.8 < 9.2.11 (CONFSERVER-101842)

medium Nessus Plugin ID 298043

Synopsis

The remote Atlassian Confluence host is missing a security update.

Description

The version of Atlassian Confluence Server running on the remote host is affected by a vulnerability as referenced in the CONFSERVER-101842 advisory.

 - pgjdbc is an open source postgresql JDBC Driver. From 42.7.4 and until 42.7.7, when the PostgreSQL JDBC driver is configured with channel binding set to required (default value is prefer), the driver would incorrectly allow connections to proceed with authentication methods that do not support channel binding (such as password, MD5, GSS, or SSPI authentication). This could allow a man-in-the-middle attacker to intercept connections that users believed were protected by channel binding requirements. This vulnerability is fixed in 42.7.7. (CVE-2025-49146)

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 9.2.11 or later.
