Eval injection vulnerability in PHPXMLRPC 1.1.1 and earlier (PEAR XML-RPC for PHP), as used in multiple products including (1) Drupal, (2) phpAdsNew, (3) phpPgAds, and (4) phpgroupware, allows remote attackers to execute arbitrary PHP code via certain nested XML tags in a PHP document that should not be nested, which are injected into an eval function call, a different vulnerability than CVE-2005-1921.
