Atlassian Jira Service Management Data Center and Server 10.0.x < 10.3.18 / 10.4.x < 11.3.10 (JSDSERVER-16727)

high Nessus Plugin ID 348389

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-16727 advisory.

 - node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.21, node-tar's filesFilter in src/list.ts uses the recursive mapHas helper to walk an archive entry path upward with path.dirname() and no segment cap when tar.t(...) or tar.x(...) receives a non-empty member-selection list. A crafted GNU L or PAX x long-path header with thousands of slash-separated segments reaches this.filter(entry.path, entry) in Parser[CONSUMEHEADER] in src/parse.ts before Unpack[CHECKPATH] applies maxDepth, causing an uncatchable RangeError stack overflow that terminates asynchronous and streaming Node.js consumers. This issue is fixed in version 7.5.21. (CVE-2026-73566)

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, 11.3.10 or later.
