Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-639: Authorization Bypass Through User-Controlled Key, where the system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. In Silverstripe/framework, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

When a secure token parameter is provided to a SilverStripe site (such as isDev or flush) an empty token parameter can be provided in order to bypass normal authentication parameters. For instance, http://www.mysite.com/?isDev=1&isDevtoken will force a site to dev mode. Alternatively, "flush" could also be used in succession to cause excessive load on a victim site and risk denial of service. The fix in this case is to ensure that empty tokens fail the validation check.
