'Name' => 'Zend Server Java Bridge Arbitrary Java Code Execution',

|
|
This module takes advantage of a trust relationship issue within the
|
|
Zend Server Java Bridge. The Java Bridge is responsible for handling interactions
|
|
between PHP and Java code within Zend Server.
|
|
|
|
When Java code is encountered Zend Server communicates with the Java Bridge. The
|
|
Java Bridge then handles the java code and creates the objects within the Java Virtual
|
|
Machine. This interaction however, does not require any sort of authentication. This
|
|
leaves the JVM wide open to remote attackers. Sending specially crafted data to the
|
|
Java Bridge results in the execution of arbitrary java code.
