Apache Storm Nimbus 2.2.0 Command Execution
Posted Nov 19, 2021
Authored by Spencer McIntyre, Alvaro Munoz | Site metasploit.com

This Metasploit module exploits an unauthenticated command injection vulnerability within the Nimbus service component of Apache Storm. The getTopologyHistory RPC method method takes a single argument which is the name of a user which is concatenated into a string that is executed by bash. In order for the vulnerability to be exploitable, there must have been at least one topology submitted to the server. The topology may be active or inactive, but at least one must be present. Successful exploitation results in remote code execution as the user running Apache Storm. This vulnerability was patched in versions 2.1.1, 2.2.1 and 1.2.4. This exploit was tested on version 2.2.0 which is affected.

ForgeRock / OpenAM Jato Java Deserialization
Posted Jul 13, 2021
Authored by Spencer McIntyre, Michael Stepankin, bwatters-r7, jheysel-r7 | Site metasploit.com

This Metasploit module leverages a pre-authentication remote code execution vulnerability in the OpenAM identity and access management solution. The vulnerability arises from a Java deserialization flaw in OpenAM's implementation of the Jato framework and can be triggered by a simple one-line GET or POST request to a vulnerable endpoint. Successful exploitation yields code execution on the target system as the service user. This vulnerability also affects the ForgeRock identity platform which is built on top of OpenAM and thus is susceptible to the same issue.

Polkit D-Bus Authentication Bypass
Posted Jul 9, 2021
Authored by Spencer McIntyre, jheysel-r7, Kevin Backhouse | Site metasploit.com

A vulnerability exists within the polkit system service that can be leveraged by a local, unprivileged attacker to perform privileged operations. In order to leverage the vulnerability, the attacker invokes a method over D-Bus and kills the client process. This will occasionally cause the operation to complete without being subjected to all of the necessary authentication. The exploit module leverages this to add a new user with a sudo access and a known password. The new account is then leveraged to execute a payload with root privileges.

Docker Container Escape
Posted Jul 1, 2021
Authored by Christophe de la Fuente, Spencer McIntyre, Nick Frichette, Borys Poplawski, Adam Iwaniuk | Site metasploit.com

This Metasploit module leverages a flaw in runc to escape a Docker container and get command execution on the host as root. This vulnerability is identified as CVE-2019-5736. It overwrites the runc binary with the payload and waits for someone to use docker exec to get into the container. This will trigger the payload execution. Note that executing this exploit carries important risks regarding the Docker installation integrity on the target and inside the container.

Win32k ConsoleControl Offset Confusion
Posted Mar 19, 2021
Authored by Spencer McIntyre, BITTER APT, LiHao, KaLendsi, MaDongZe, TuXiaoYi, JinQuan | Site metasploit.com

A vulnerability exists within win32k that can be leveraged by an attacker to escalate privileges to those of NT AUTHORITY\SYSTEM. The flaw exists in how the WndExtra field of a window can be manipulated into being treated as an offset despite being populated by an attacker-controlled value. This can be leveraged to achieve an out of bounds write operation, eventually leading to privilege escalation.

Sudo 1.8.31p2 / 1.9.5p1 Buffer Overflow
Posted Feb 5, 2021
Authored by Blasty, Spencer McIntyre, Qualys Security Advisory, bwatters-r7, Alexander Krog | Site metasploit.com

A heap based buffer overflow exists in the sudo command line utility that can be exploited by a local attacker to gain elevated privileges. The vulnerability was introduced in July of 2011 and affects version 1.8.2 through 1.8.31p2 as well as 1.9.0 through 1.9.5p1 in their default configurations. The technique used by this implementation leverages the overflow to overwrite a service_user struct in memory to reference an attacker controlled library which results in it being loaded with the elevated privileges held by sudo.

Apache Struts 2 Forced Multi OGNL Evaluation
Posted Dec 24, 2020
Authored by Matthias Kaiser, Spencer McIntyre, Alvaro Munoz, ka1n4t | Site metasploit.com

The Apache Struts framework, when forced, performs double evaluation of attribute values assigned to certain tags attributes such as id. It is therefore possible to pass in a value to Struts that will be evaluated again when a tag's attributes are rendered. With a carefully crafted request, this can lead to remote code execution. This vulnerability is application dependant. A server side template must make an affected use of request data to render an HTML tag attribute.

Telerik UI ASP.NET AJAX RadAsyncUpload Deserialization
Posted Oct 20, 2020
Authored by Spencer McIntyre, Oleksandr Mirosh, Markus Wulftange, Alvaro Munoz, Paul Taylor, Caleb Gross, straightblast | Site metasploit.com

This Metasploit module exploits the .NET deserialization vulnerability within the RadAsyncUpload (RAU) component of Telerik UI ASP.NET AJAX that is identified as CVE-2019-18935. In order to do so the module must upload a mixed mode .NET assembly DLL which is then loaded through the deserialization flaw. Uploading the file requires knowledge of the cryptographic keys used by RAU. The default values used by this module are related to CVE-2017-11317, which once patched randomizes these keys. It is also necessary to know the version of Telerik UI ASP.NET that is running. This version number is in the format YYYY.#(.###)? where YYYY is the year of the release (e.g. 2020.3.915).

SharePoint DataSet / DataTable Deserialization
Posted Jul 31, 2020
Authored by Soroush Dalili, mr_me, Spencer McIntyre | Site metasploit.com

A remotely exploitable vulnerability exists within SharePoint that can be leveraged by a remote authenticated attacker to execute code within the context of the SharePoint application service. The privileges in this execution context are determined by the account that is specified when SharePoint is installed and configured. The vulnerability is related to a failure to validate the source of XML input data, leading to an unsafe deserialization operation that can be triggered from a page that initializes either the ContactLinksSuggestionsMicroView type or a derivative of it. In a default configuration, a Domain User account is sufficient to access SharePoint and exploit this vulnerability.

Plesk / myLittleAdmin ViewState .NET Deserialization
Posted May 22, 2020
Authored by Spencer McIntyre, wvu | Site metasploit.com

This Metasploit module exploits a ViewState .NET deserialization vulnerability in web-based MS SQL Server management tool myLittleAdmin, for version 3.8 and likely older versions, due to hardcoded machineKey parameters in the web.config file for ASP.NET. Popular web hosting control panel Plesk offers myLittleAdmin as an optional component that is selected automatically during "full" installation. This exploit caters to the Plesk target, though it should work fine against a standalone myLittleAdmin setup. Successful exploitation results in code execution as the user running myLittleAdmin, which is IUSRPLESK_sqladmin for Plesk and described as the "SQL Admin MSSQL anonymous account". Tested on the latest Plesk Obsidian with optional myLittleAdmin 3.8.
