  • Security: SQL injection in Versioned.php


Security: Require ADMIN for ?flush=1 and ?flush=all

Flushing the various manifests (class, template, config) is performed through a GET parameter (flush=1). Since this action requires more server resources than normal requests, it can facilitate denial-of-service attacks.

To prevent this, main.php now checks and only allows the flush parameter in the following cases:

  • The environment is in "dev mode"
  • A user is logged in with ADMIN permissions
  • An error occurs during startup

This applies to both flush=1 and flush=allbut only through web requests made through main.php - CLI requests, or any other request that goes through a custom start up script will still process all flush requests as normal.

Thanks to Christopher Tombleson for reporting.

Security: SQL injection in Versioned.php

The archiveDate parameter wasn't correctly escaping user input through URL parameters (download patch)

Thanks to Dean Jerkovich of NCC Group for reporting.
