Kemp LoadMaster Local sudo Privilege Escalation
Posted May 13, 2024
Authored by bwatters-r7, Dave Yesland | Site metasploit.com

This Metasploit module abuses a feature of the sudo command on Progress Kemp LoadMaster. Certain binary files are allowed to automatically elevate with the sudo command. This is based off of the file name. Some files have this permission are not write-protected from the default bal user. As such, if the file is overwritten with an arbitrary file, it will still auto-elevate. This module overwrites the /bin/loadkeys file with another executable.

Themebleed Windows 11 Themes Arbitrary Code Execution
Posted Jan 5, 2024
Authored by Spencer McIntyre, bwatters-r7, gabe_k | Site metasploit.com

When an unpatched Windows 11 host loads a theme file referencing an msstyles file, Windows loads the msstyles file, and if that file's PACKME_VERSION is 999, it then attempts to load an accompanying dll file ending in _vrf.dll. Before loading that file, it verifies that the file is signed. It does this by opening the file for reading and verifying the signature before opening the file for execution. Because this action is performed in two discrete operations, it opens the procedure for a time of check to time of use vulnerability. By embedding a UNC file path to an SMB server we control, the SMB server can serve a legitimate, signed dll when queried for the read, but then serve a different file of the same name when the host intends to load/execute the dll.

Microsoft Error Reporting Local Privilege Elevation
Posted Sep 27, 2023
Authored by bwatters-r7, Filip Dragovic, Octoberfest7 | Site metasploit.com

This Metasploit module takes advantage of a bug in the way Windows error reporting opens the report parser. If you open a report, Windows uses a relative path to locate the rendering program. By creating a specific alternate directory structure, we can coerce Windows into opening an arbitrary executable as SYSTEM. If the current user is a local admin, the system will attempt impersonation and the exploit will fail.

MOVEit SQL Injection
Posted Jun 23, 2023
Authored by bwatters-r7, sfewer-r7, rbowes-r7 | Site metasploit.com

This Metasploit module exploits an SQL injection vulnerability in the MOVEit Transfer web application that allows an unauthenticated attacker to gain access to MOVEit Transfer's database. Depending on the database engine being used (MySQL, Microsoft SQL Server, or Azure SQL), an attacker can leverage an information leak be able to upload a .NET deserialization payload.

Watch Queue Out-Of-Bounds Write
Posted Apr 21, 2022
Authored by Jann Horn, bwatters-r7, bonfee | Site metasploit.com

This Metasploit module exploits a vulnerability in the Linux Kernel's watch_queue event notification system. It relies on a heap out-of-bounds write in kernel memory. The exploit may fail on the first attempt so multiple attempts may be needed. Note that the exploit can potentially cause a denial of service if multiple failed attempts occur, however this is unlikely.

Polkit pkexec Local Privilege Escalation
Posted Mar 3, 2022
Authored by Qualys Security Advisory, Dhiraj Mishra, bwatters-r7, Andris Raugulis | Site metasploit.com

This is a Metasploit module for the argument processing bug in the polkit pkexec binary. If the binary is provided with no arguments, it will continue to process environment variables as argument variables, but without any security checking. By using the execve call we can specify a null argument list and populate the proper environment variables. This exploit is architecture independent.

Ubuntu Overlayfs Local Privilege Escalation
Posted Dec 3, 2021
Authored by bwatters-r7, ssd-disclosure | Site metasploit.com

This Metasploit module exploits a vulnerability in Ubuntu's implementation of overlayfs. The vulnerability is the result of failing to verify the ability of a user to set the attributes in a running executable. Specifically, when Overlayfs sends the set attributes data to the underlying file system via vfs_setxattr, it fails to first verify the data by calling cap_convert_nscap. This vulnerability was patched by moving the call to cap_convert_nscap into the vfs_setxattr function that sets the attribute, forcing verification every time the vfs_setxattr is called rather than trusting the data was already verified.

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.

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.

Microsoft Spooler Local Privilege Elevation
Posted Jan 18, 2021
Authored by bwatters-r7, Peleg Hadar, sailay1996, 404death, Tomer Bar | Site metasploit.com

This exploit leverages a file write vulnerability in the print spooler service which will restart if stopped. Because the service cannot be stopped long enough to remove the dll, there is no way to remove the dll once it is loaded by the service. Essentially, on default settings, this module adds a permanent elevated backdoor.

Windows Escalate UAC Protection Bypass Via Dot Net Profiler
Posted Nov 19, 2019
Authored by Stefan Kanthak, Casey Smith, bwatters-r7 | Site metasploit.com

Microsoft Windows allows for the automatic loading of a profiling COM object during the launch of a CLR process based on certain environment variables ostensibly to monitor execution. In this case, the authors abuse the profiler by pointing to a payload DLL that will be launched as the profiling thread. This thread will run at the permission level of the calling process, so an auto-elevating process will launch the DLL with elevated permissions. In this case, they use gpedit.msc as the auto-elevated CLR process, but others would work, too.

This Metasploit module exploits a flaw in the WSReset.exe file associated with the Windows Store. This binary has autoelevate privs, and it will run a binary file contained in a low-privilege registry location. By placing a link to the binary in the registry location, WSReset.exe will launch the binary as a privileged user.

Microsoft Windows ALPC Task Scheduler Local Privilege Elevation
Posted Sep 22, 2018
Authored by Jacob Robles, bwatters-r7, SandboxEscaper, asoto-r7 | Site metasploit.com

On vulnerable versions of Windows the alpc endpoint method SchRpcSetSecurity implemented by the task scheduler service can be used to write arbitrary DACLs to .job files located in c:\windows\tasks because the scheduler does not use impersonation when checking this location. Since users can create files in the c:\windows\tasks folder, a hardlink can be created to a file the user has read access to. After creating a hardlink, the vulnerability can be triggered to set the DACL on the linked file. WARNING: The PrintConfig.dll (%windir%\system32\driverstor\filerepository\prnms003*) on the target host will be overwritten when the exploit runs. This Metasploit module has been tested against Windows 10 Pro x64.
