In this advisory: Security vulnerabilitiesXSS vulnerability in Issue ActionsSeverityAtlassian rates this vulnerability as HIGH, according to the scale published in the JIRA Security documentation. This scale allows us to rank a vulnerability as critical, high, moderate or low. Risk AssessmentWe have identified and fixed a security flaw which may affect JIRA instances in a public environment. This flaw is an XSS (cross-site scripting) vulnerability in JIRA's 'Saved Filter', 'Filter Statistics', 'Project Statistics' and '2D Filter Statistics' portlets. This potentially allows a malicious user (hacker) to create a shared filter with special JavaScript in the name, and then create a link to run the vulnerable portlets using the shared filter. If this link was sent to a user and clicked by the user, the special JavaScript would be executed in the user's session.
Atlassian recommends that you upgrade to JIRA 3.12.2, or download the patch for JIRA 3.12.1, 3.11 or 3.10.2, to fix the vulnerabilities described below. You can read more about XSS attacks at cgisecurity, CERT and other places on the web. Risk MitigationIf you judge it necessary, you can disable public access (i.e. anonymous access and public signup) to your JIRA system until you have applied the necessary patch or upgrade. For even tighter control, you could restrict JIRA access to trusted groups only. VulnerabilityThe 'Saved Filter', 'Filter Statistics', 'Project Statistics' and '2D Filter Statistics' portlets are affected. The name of a shared filter is not HTML-escaped when the the portlet is viewed. FixThe fix is to escape the name of a shared filter when run by the 'Saved Filter', 'Filter Statistics', 'Project Statistics' and '2D Filter Statistics' portlets, so that no content in the filter name is interpreted as HTML or CSS. This issue has been fixed in JIRA 3.12.2. The fix is also provided as a patch for JIRA 3.12.1, 3.11 and 3.10.2. For more information, please see JRA-14277 and JRA-14357.
