The Revive Adserver team announces the immediate availability of Revive Adserver v4.2.1.

Revive Adserver logoWe are pleased to announce a new release of the Revive Adserver software, which has been given version number v4.2.1. This new version fixes a number of bugs that were discovered since the last 4.2.0 release, and it also addresses one security issue that has been discovered recently.

Here are the most important changes included in Revive Adserver v4.2.1:

  • We fixed an issue with the “Active Campaigns” filter, which was incorrectly hiding campaigns if it contained at least one inactive banner, and depending on the order of active or inactive banners found for the campaign.
  • We fixed an issue with some of the required PHP extensions for Revive Adserver not being displayed in the pre-install/upgrade check screen.

Security fix

This version 4.2.1 also contains a fix for one vulnerability that was recently discovered and reported to us through our HackerOne security program.

We strongly advise people to upgrade to the most recent 4.2.1 version of Revive Adserver as soon as possible.

In case that is not immediately feasible, we especially recommend to delete or block the www/admin/password-recovery.php script.
