Vulnerability: SQL injection

Description

An SQL-injection vulnerability was recently discovered and reported to the Revive Adserver team by Florian Sander. The vulnerability is known to be already exploited to gain unauthorised access to the application using brute force mechanisms, however other kind of attacks might be possible and/or already in use. The risk is rated to be critical as the most common end goal of the attackers is to spread malware to the visitors of all the websites and ad networks that the ad server is being used on.

The vulnerability is also present and exploitable in OpenX Source 2.8.11 and earlier versions, potentially back to phpAdsNew 2.0.x.

Details

The XML-RPC delivery invocation script was failing to escape its input parameters in the same way the other delivery methods do, allowing attackers to inject arbitrary SQL code via the “what” parameter of the delivery XML-RPC methods. Also, the escaping technique used to handle such parameter in the delivery scripts was based on the addslashes PHP function and has now been upgraded to use the dedicated escaping functions for the database in use.

Solution

We strongly advise people to upgrade to the most recent 3.0.2 version of Revive Adserver, including those running OpenX Source or older versions of the application.

In case the upgrade cannot be performed in a timely fashion, we suggest to delete the “www/delivery/axmlrpc.php” script (if not in use) as a temporary fix until the application is upgraded.
