Atlassian Confluence 7.13.15 < 7.13.19 / 7.19.7 < 7.19.11 / 8.1.1 < 8.4.1 DoS (CONFSERVER-90185)

high Nessus Plugin ID 179901

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-90185 advisory.

- The fix for CVE-2023-24998 was incomplete for Apache Tomcat 11.0.0-M2 to 11.0.0-M4, 10.1.5 to 10.1.7, 9.0.71 to 9.0.73 and 8.5.85 to 8.5.87. If non-default HTTP connector settings were used such that the maxParameterCount could be reached using query string parameters and a request was submitted that supplied exactly maxParameterCount parameters in the query string, the limit for uploaded request parts could be bypassed with the potential for a denial of service to occur.

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 7.13.19, 7.19.11, 8.4.1 or later.
