Zend Server Java Bridge Arbitrary Java Code Execution - Metasploit
This page contains detailed information about how to use the exploit/multi/misc/zend_java_bridge metasploit module. For list of all metasploit modules, visit the Metasploit Module Library.
Module Overview
Name: Zend Server Java Bridge Arbitrary Java Code Execution
Module: exploit/multi/misc/zend_java_bridge
Source code: modules/exploits/multi/misc/zend_java_bridge.rb
Disclosure date: 2011-03-28
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): java
Supported platform(s): Java
Target service / protocol: -
Target network port(s): 10001
List of CVEs: -
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.
Module Ranking and Traits
Module Ranking:
- great: The exploit has a default target AND either auto-detects the appropriate target or uses an application-specific return address AFTER a version check. More information about ranking can be found here.
Basic Usage
msf > use exploit/multi/misc/zend_java_bridge
msf exploit(zend_java_bridge) > exploit
Required Options
- RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
