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-99686 advisory.

 - Improper Input Validation vulnerability in Apache Tomcat. Incorrect error handling for some invalid HTTP priority headers resulted in incomplete clean-up of the failed request which created a memory leak. A large number of such requests could trigger an OutOfMemoryException resulting in a denial of service. This issue affects Apache Tomcat: from 9.0.76 through 9.0.102, from 10.1.10 through 10.1.39, from 11.0.0-M2 through 11.0.5. Users are recommended to upgrade to version 9.0.104, 10.1.40 or 11.0.6 which fix the issue. (CVE-2025-31650)

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 8.5.22, 9.2.4, 9.4.1 or later.
