high Nessus Plugin ID 304691

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-16528 advisory.

- node-tar is a Tar for Node.js. The node-tar library (<= 7.5.2) fails to sanitize the linkpath of Link (hardlink) and SymbolicLink entries when preservePaths is false (the default secure behavior). This allows malicious archives to bypass the extraction root restriction, leading to Arbitrary File Overwrite via hardlinks and Symlink Poisoning via absolute symlink targets. This vulnerability is fixed in 7.5.3.
(CVE-2026-23745)

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 10.3.18, 11.3.3 or later.
