This module exploits a vulnerability in Linux. The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel through 4.3.3 attempts to merge distinct setattr operations, which allows local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application.

The default Jenkins configuration allows to execute groovy scripts without being authenticated.

The 'sosreport' program, part of the ABRT bug reporting system used in Red Hat Enterprise Linux, does not handle symbolic links correctly when writing core dumps of ABRT programs to the ABRT dump directory (/var/tmp/abrt). This can be leveraged by local unprivileged attackers to gain root privileges on vulnerable systems.

This module exploits a remote code execution vulnerability in Joomla. The session handling code is susceptible to PHP Object Injection attacks due to lack of sanitization in some HTTP headers that are saved to the database session backend.

Oracle WebLogic Server is prone to a remote vulnerability that allows attackers to take advantage of a deserialization vulnerability present in the commons-collections Java library. By exploiting known methods, it is possible to remotely load a InvokerTransformer Java class, wich allows the execution of system commands.

Jenkins is prone to a remote vulnerability that allows attackers to take advantage of a deserialization vulnerability present in the commons-collections Java library. By exploiting known methods, it is possible to remotely load a InvokerTransformer Java class, which allows the execution of system commands.

JBoss Application Server is prone to a remote vulnerability that allows attackers to take advantage of a deserialization vulnerability present in the commons-collections java library. By exploiting known methods, it is possible to remotely load a InvokerTransformer java class, wich allows the execution of system commands.

The 'fusermount' binary, part of the FUSE system in Linux, executes the /bin/mount binary with ruid set to 0 without clearing the environment variables provided by unprivileged users. This flaw can be leveraged by local unprivileged users to gain root privileges by leveraging the functionality provided by the LIBMOUNT_MTAB environment variable to overwrite an arbitrary file on the affected system. This module will try to overwrite the /etc/bash.bashrc file, which is executed every time any user spawns an interactive Bash shell. That means that a new agent will be deployed every time any user opens a new interactive shell (either login or non-login ones) on the vulnerable machine. Note that this also means that installed agents will run with the privileges of the users that have launched interactive shells. Unlike other privilege escalation exploits, this module will not stop after installing the first agent; it will stay running until a new agent with root permissions is installed (that is, if the root user happens to run an interactive shell on the vulnerable machine), or until the user-specified time limit is reached, whatever happens first. Note that non-root agents will be kept, since they still can be valuable despite not having superuser privileges.

This module exploits a command injection vulnerability in HP Client Automation. The flaw exists within the radexecd.exe component which listens by default on TCP port 3465. When handling a remote execution request the process does not properly authenticate the user issuing the request. The command to be executed is also not properly sanitized. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of SYSTEM. Authentication is not required to exploit this vulnerability.

Elasticsearch allows limited execution of Groovy code during search operations. A vulnerability exists in versions below 1.4.3, by which a sandbox escape is possible. This module installs an OS agent against vulnerable installations.
