HTML/Script Code Injection Vulnerability when operating with multiple languages

Published: June 11, 2008

Version: 1.0

Maximum Severity Rating: Low

Background

To support switching between languages via the Language skin object, the skin object renders the existing page path along with the relevant country flag and a language token.

Issue Summary

The language skin object failed to encode the newly generated paths which meant that a hacker could inject html/script to perform cross-site scripting attacks.

Mitigating factors

Only DotNetNuke sites that have multiple language pack installs and use the Language skin object suffer from this flaw.

Affected DotNetNuke versions

All others

Non-Affected Versions:

N/A

Fix(s) for issue

To fix this problem, you are recommended to update to the latest version of DotNetNuke (4.8.4 at time of writing)
