Atlassian JIRA < 7.13.12 / 8.x < 8.5.4 / 8.6.x < 8.6.1 'Atlassian Application Links' Plugin Privilege Escalation

Medium Nessus Plugin ID 134759


The remote web server hosts a web application that is potentially affected by a privilege escalation vulnerability.


According to its self-reported version number, the instance of Atlassian JIRA hosted on the remote web server is before 7.13.12, or 8.x before 8.5.4, or 8.6.x before 8.6.1. It is, therefore, affected by an improper authorization check related to the Atlassian Application Links plugin that allows a remote attacker with administrator privileges to edit existing applinks without passing 'WebSudo'.


Upgrade to Atlassian JIRA version 7.13.12 / 8.5.4 / 8.6.1 or later.
