Change localized text to stop user enumeration

Published: Jan 19, 2011

Version: 1.1 (edited 27 June 2011)

Maximum Severity Rating: Low

Background

DotNetNuke supports the ability for the user to get a copy of their password emailed out if they have forgotten it.

Issue Summary

The messages returned from the forgot password utility were too detailed, and could be used to identify the existance of user accounts.

Mitigating factors

This only affects sites where the forgot password utility is used. If the authentication provider does not support this, or has enablePasswordRetrieval set to false in web.config, no action is required.

Affected DotNetNuke versions

  • 3.0-5.6.0

Non-Affected Versions:

  • All other versions

Fix(s) for issue

To fix this problem, you are recommended to update to the latest version of DotNetNuke (5.6.1 at time of writing)
