DESCRIPTION:
OLiBekaS has discovered a vulnerability in ezUserManager, which can
be exploited by malicious people to compromise a vulnerable system.

Input passed to the "ezUserManager_Path" parameter in
ezusermanager_core.inc.php is not properly verified before being used
to include files. This can be exploited to execute arbitrary PHP code
by including files from local or external resources.

Successful exploitation is possible by accessing
ezusermanager_pwd_forgott.php, which includes
ezusermanager_core.inc.php, but requires that "register_globals" is
enabled.

The vulnerability has been confirmed in version 1.6. Other versions
may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified.
