DESCRIPTION:
RedTeam has reported two vulnerabilities in PAJAX, which can be
exploited by malicious people to compromise a vulnerable system.

1) Input passed to the "method" and "args" parameters in
pajax_call_dispatcher.php is not properly sanitised before being
used. This can be exploited to inject and execute arbitrary PHP code
on the system.

2) Input passed to the "className" variable is not properly sanitised
before being used to include files. This can be exploited to include
arbitrary .class.php files on the system via directory traversal
attacks.

The vulnerabilities have been reported in version 0.5.1. Prior
versions may also be affected.

SOLUTION:
Update to version 0.5.2.
