Summary
AdminNeo: version-cache array injection causes persistent denial of service
Details

AdminNeo is a full-featured database management tool written in PHP. From 4.6.2 until 5.5.0, the unauthenticated ?script=version endpoint accepts POST data without origin, CSRF or parameter-type validation. A version[] parameter becomes a PHP array that bootstrap.inc.php serializes into the shared adminneo.version cache. On later page loads, design.inc.php passes that cached value to cookie() and rawurlencode(), causing a TypeError rather than encoding a version string. A remote attacker can make the instance return HTTP 500 to all users for the cache's twenty-four-hour lifetime or until the poisoned cache is removed. Exploitation requires the web server to be able to write that shared cache; making it unwritable is an interim workaround. The issue retains the underlying type-validation defect reported previously in Adminer despite changes to AdminNeo's version-checking flow. This issue is fixed in version 5.5.0.
