Atlassian Jira Service Management Data Center and Server 5.15.2 < 10.3.20 / 10.4.x < 11.3.5 (JSDSERVER-16574)

high Nessus Plugin ID 318800

Synopsis

The remote Atlassian Jira Service Management Data Center and Server (Jira Service Desk) host is missing a security update.

Description

The version of Atlassian Jira Service Management Data Center and Server (Jira Service Desk) running on the remote host is affected by a vulnerability as referenced in the JSDSERVER-16574 advisory.

- The brace-expansion library generates arbitrary strings containing a common prefix and suffix. Prior to versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13, a brace pattern with a zero step value (e.g., `{1..2..0}`) causes the sequence generation loop to run indefinitely, making the process hang for seconds and allocate heaps of memory. Versions 5.0.5, 3.0.2, 2.0.3, and 1.1.13 fix the issue. As a workaround, sanitize strings passed to `expand()` to ensure a step value of `0` is not used. (CVE-2026-33750)

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 Jira Service Management Data Center and Server version 10.3.20, 11.3.5 or later.
