CakePHP-SA-11/14/2010: CakePHP <= 1.3.5 / 1.2.8 unserialize() Vulnerability
CakePHP is vulnerable to a file inclusion attack because of its use of
the
"unserialize()" function on unchecked user input. This makes it possible
to inject arbitary objects into the scope.
Details:
The $check array contains our POST data and $locked is
a simple (rot-13 obfuscated) serialized string, which is completely
under our control.
PHP5 introduces a destructor with the "__destruct" method. Each object
will execute its __destruct method at the end of its lifetime and we can
use this to turn an unchecked unserialize() call in an useful exploit.
