Atlassian Confluence < 7.4.17 / 7.13.x < 7.13.6 / < 7.14.3 / 7.15.x < 7.15.2 / 7.16.x < 7.16.4 / 7.17.x < 7.17.2 (CONFSERVER-79483)

critical Nessus Plugin ID 163327


The remote Atlassian Confluence host is missing a security update.


The version of Atlassian Confluence installed on the remote host is prior to < 7.4.17 / 7.13.x < 7.13.6 / 7.14.x < 7.14.3 / 7.15.x < 7.15.2 / 7.16.x < 7.16.4 / 7.17.x < 7.17.2. It is potentially affected by a hard-coded credential vulnerability if the 'Questions for Confluence' app is installed.

The Atlassian Questions For Confluence app for Confluence Server and Data Center creates a Confluence user account in the confluence-users group with the username disabledsystemuser and a hardcoded password. A remote, unauthenticated attacker with knowledge of the hardcoded password could exploit this to log into Confluence and access all content accessible to users in the confluence-users group. This user account is created when installing versions 2.7.34, 2.7.35, and 3.0.2 of the app.(CVE-2022-26138)

Note that Nessus has not tested for this issue but has instead relied only on Confluence's self-reported version number. This plugin will only run in 'Parnoid' scans.


Upgrade to Atlassian Confluence version 7.4.17, 7.13.6, 7.14.3, 7.15.2, 7.16.4, 7.17.2, 7.13.6, 7.14.3, 7.15.2, 7.16.4, 7.17.2 or later.
