In this advisory:
Parameter-Based Redirection Vulnerability
Atlassian rates this vulnerability as high, according to the scale published in Severity Levels for Security Issues. The scale allows us to rank a vulnerability as critical, high, moderate or low. This vulnerability is not critical.
This is an independent assessment and you should evaluate its applicability to your own IT environment.
Parameter-based redirection vulnerabilities allow an attacker to craft a JIRA URL in such a way that a user clicking on this URL will be redirected to a different web site. This can be used for phishing.
Some actions in JIRA redirect users to a new page after the action has been completed. It was possible to hand-craft an URL that would redirect to a site outside the current instance of JIRA. Starting with JIRA 4.2.2 all such redirections are limited to pages inside the current instance of JIRA.
All versions of JIRA prior to 4.2.2 are affected.
We recommend upgrading your JIRA installation to fix this vulnerability. Please see the 'Fix' section below.
These issues have been fixed in these notes href="/display/JIRA/JIRA+4.2.2+Release+Notes">JIRA 4.2.2 and later.
We have created a patch for the latest maintenance release 4.1.2 of JIRA for this vulnerability.
