Atlassian JIRA 6.0 < 8.5.5 / 8.6 < 8.8.1 XSS (JRASERVER-70923)

medium Nessus Plugin ID 137065

Language:

Synopsis

The remote web server hosts a web application that is affected by a cross-site scripting vulnerability.

Description

According to its self-reported version number, the instance of Atlassian JIRA hosted on the remote web server is 6.x prior to 8.5.5 or 8.6.x prior to 8.8.1. It is, therefore, affected by a cross-site scripting (XSS) vulnerability in its view issue screen due to improper validation of user-supplied input before returning it to users. An authenticated, remote attacker can exploit this, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.
 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 version 8.5.5, 8.8.1, 8.9.0 or later.
