In this advisory:
XSS Vulnerability in Dashboard Action
Atlassian rates this vulnerability as high, according to the scale published in Confluence Security. The scale allows us to rank a vulnerability as critical, high, moderate or low.
- The hacker might take advantage of this flaw to steal other users' session cookies or other credentials, by sending the credentials back to the hacker's own web server.
- The hacker's text and script might be displayed to other people viewing the Confluence page. This is potentially damaging to your company's reputation.
To fix the vulnerabilities described below, Atlassian recommends that you take one of the following steps:
- Upgrade to Confluence 2.7.1, or
- Download and install the patch for Confluence 2.6.2 or Confluence 2.7.0 from our JIRA site – see issue CONF-10289.
If you judge it necessary, you can disable public access (e.g. anonymous access and public signon) to your wiki until you have applied the necessary patch or upgrade. For even tighter control, you could restrict access to trusted groups only.
The above Confluence action is used to determine which spaces are listed on a user's Dashboard. For example, the following URL requests a list of team spaces only:
The action is invoked when a user selects one of the 'Spaces' tabs on the Dashboard, such as the 'Team' tab. It can also be invoked by simply entering the URL into the browser address bar.
A patch is available for Confluence 2.6.2 and Confluence 2.7.0. For more information, please see CONF-10289.
