Opentext Documentum Content Server (formerly known as EMC Documentum Content Server) allows for privilege escalation via traversal attacks leveraged through uploaded tar files.
8f058be0fbb3dae75f3313418482761ee598bb48de892ffce1875c79cccba63dA vulnerability exists in the Windows Ancillary Function Driver for Winsock (afd.sys) can be leveraged by an attacker to escalate privileges to those of NT AUTHORITY\SYSTEM. Due to a flaw in AfdNotifyRemoveIoCompletion, it is possible to create an arbitrary kernel Write-Where primitive, which can be used to manipulate internal I/O ring structures and achieve local privilege escalation. This exploit only supports Windows 11 22H2 up to build 22621.963 (patched in January 2023 updates).
d5a189a643f3c07d66a853b96018a65f135901780840ff23dc17f6a405330ebbThis Metasploit module demonstrates how an incorrect access control for the Lenovo Diagnostics Driver allows a low-privileged user the ability to issue device IOCTLs to perform arbitrary physical/virtual memory reads and writes.
4d81e8f2ae72805082f511a1afa0427bff321c86d10fa56019672dac926e51f8This Metasploit module exploits a bug in io_uring leading to an additional put_cred() that can be exploited to hijack credentials of other processes. This exploit will spawn SUID programs to get the freed cred object reallocated by a privileged process and abuse them to create a SUID root binary that will pop a shell. The dangling cred pointer will, however, lead to a kernel panic as soon as the task terminates and its credentials are destroyed. We therefore detach from the controlling terminal, block all signals and rest in silence until the system shuts down and we get killed hard, just to cry in vain, seeing the kernel collapse. The bug affected kernels from v5.12-rc3 to v5.14-rc7. More than 1 CPU is required for exploitation. Successfully tested against Ubuntu 22.04.01 with kernel 5.13.12-051312-generic.
ddab5b3975fc82e2a23c5e4e05a57af4893abfbc613df02d507c1013c62dc088The print spooler service can be abused by an authenticated remote attacker to load a DLL through a crafted DCERPC request, resulting in remote code execution as NT AUTHORITY\SYSTEM. This module uses the MS-RPRN vector which requires the Print Spooler service to be running.
1720ad267b345d6b91409cdb01c0ab129fc9f485ac71c4c4a816698bd6351239This 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.
b59181d9b536ad31ebdc6b3f83985c65e49fbe3242468f7709e7bb7a2d4b1e5fThe user profile service, identified as ProfSrv, is vulnerable to a local privilege elevation vulnerability in its CreateDirectoryJunction() function due to a lack of appropriate checks on the directory structure of the junctions it tries to link together. Attackers can leverage this vulnerability to plant a malicious DLL in a system directory and then trigger a UAC prompt to cause this DLL to be loaded and executed by ProfSrv as the NT AUTHORITY\SYSTEM user. Note that this bug was originally identified as CVE-2021-34484 and was subsequently patched a second time as CVE-2022-21919, however both patches were found to be insufficient. This bug is a patch bypass for CVE-2022-21919 and at the time of publishing, has not yet been patched, though plans are in place to patch it as CVE-2022-26904.
d30eae074af8b00dd694a057dd1c7a07694de0851d5e48da9ee462ed23d2a3ceThis Metasploit module exploits a stack buffer overflow in ALLMediaServer version 1.6. The vulnerability is caused due to a boundary error within the handling of HTTP request.
ec5996d7542530d1bdb600e24891e2ffa7033a9c24319db14a34043fa0b9fec3The Windows Print Spooler has a privilege escalation vulnerability that can be leveraged to achieve code execution as SYSTEM. The SpoolDirectory, a configuration setting that holds the path that a printer's spooled jobs are sent to, is writable for all users, and it can be configured via SetPrinterDataEx() provided the caller has the PRINTER_ACCESS_ADMINISTER permission. If the SpoolDirectory path does not exist, it will be created once the print spooler reinitializes. Calling SetPrinterDataEx() with the CopyFiles\ registry key will load the dll passed in as the pData argument, meaning that writing a dll to the SpoolDirectory location can be loaded by the print spooler. Using a directory junction and UNC path for the SpoolDirectory, the exploit writes a payload to C:\Windows\System32\spool\drivers\x64\4 and loads it by calling SetPrinterDataEx(), resulting in code execution as SYSTEM.
3e62199fe39127be4320ed28c4a8d52211edb9c506d1e42a0aba3faef33cb58cThis Metasploit module exploits a vulnerability that has been in the Linux kernel since version 5.8. It allows writing of read only or immutable memory. The vulnerability was fixed in Linux 5.16.11, 5.15.25 and 5.10.102. The module exploits this vulnerability by overwriting a suid binary with the payload, executing it, and then writing the original data back. There are two major limitations of this exploit: the offset cannot be on a page boundary (it needs to write one byte before the offset to add a reference to this page to the pipe), and the write cannot cross a page boundary. This means the payload must be less than the page size (4096 bytes).
95e39ce5f94de2996183947c580313fe0356df719e22343a89d095b460489c7aThis 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.
45168e34096e858ea0c2f1c2c12695c4121ec633a36c09aef6de9a8d95de3371A 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. This flaw was originally identified as CVE-2021-1732 and was patched by Microsoft on February 9th, 2021. In early 2022, a technique to bypass the patch was identified and assigned CVE-2022-21882. The root cause is is the same for both vulnerabilities. This exploit combines the patch bypass with the original exploit to function on a wider range of Windows 10 targets.
9902434a58e36c7838c71ee860592d8624368fc1b380cf4c9ccf530f09895fd2This 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.
db2db701a06e20ebab9c0759df9c3b43a3146ecf6b60cce3c13e3d0541420302A use after free vulnerability exists in the NtGdiResetDC() function of Win32k which can be leveraged by an attacker to escalate privileges to those of NT AUTHORITY\SYSTEM. The flaw exists due to the fact that this function calls hdcOpenDCW(), which performs a user mode callback. During this callback, attackers can call the NtGdiResetDC() function again with the same handle as before, which will result in the PDC object that is referenced by this handle being freed. The attacker can then replace the memory referenced by the handle with their own object, before passing execution back to the original NtGdiResetDC() call, which will now use the attacker's object without appropriate validation. This can then allow the attacker to manipulate the state of the kernel and, together with additional exploitation techniques, gain code execution as NT AUTHORITY\SYSTEM. This Metasploit module has been tested to work on Windows 10 x64 RS1 (build 14393) and RS5 (build 17763), however previous versions of Windows 10 will likely also work.
d461ac15b5e26e34c254c715db3521b7fe5d55e6fa9001b97d36ac89cbec7782This Metasploit module demonstrates that by removing the authentication exchange, an attacker can issue requests to the local OMI management socket that will cause it to execute an operating system command as the root user. This vulnerability was patched in OMI version 1.6.8-1 (released September 8th 2021).
421ae743686547f1ecd98e3086fa9370482e6a9646a5f30c18b32491b7848309By removing the authentication header, an attacker can issue an HTTP request to the OMI management endpoint that will cause it to execute an operating system command as the root user. This vulnerability was patched in OMI version 1.6.8-1 (released September 8th 2021).
fdef0aef0e912b6be1749a8d91235a8ce5f95d8c64ee36efaa66917951a81206Linux kernels from 5.7-rc1 prior to 5.13-rc4, 5.12.4, 5.11.21, and 5.10.37 are vulnerable to a bug in the eBPF verifier's verification of ALU32 operations in the scalar32_min_max_and function when performing AND operations, whereby under certain conditions the bounds of a 32 bit register would not be properly updated. This can be abused by attackers to conduct an out of bounds read and write in the Linux kernel and therefore achieve arbitrary code execution as the root user. The target system must be compiled with eBPF support and not have kernel.unprivileged_bpf_disabled set, which prevents unprivileged users from loading eBPF programs into the kernel. Note that if kernel.unprivileged_bpf_disabled is enabled this module can still be utilized to bypass protections such as SELinux, however the user must already be logged as a privileged user such as root.
72309dfd15f65e29e815be3b1add6fc3b2c2baad6cb3b01ac2bbfff15a8b2c9dThis 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.
7ab7e165e1eabb4c0774d5b02fa501308e44a10ac91af40c1b4ed6a62fc60ca6The DBUtil_2_3.sys driver distributed by Dell exposes an unprotected IOCTL interface that can be abused by an attacker to read and write kernel-mode memory.
60c28ef1ac35891f12da2b7098fca05a34362d8c69f7050055509277585d70abThis Metasploit module exploits the CVE-2020-6207 vulnerability within the SAP EEM servlet of SAP Solution Manager (SolMan) running version 7.2. The vulnerability occurs due to missing authentication checks when submitting a SOAP request to the /EemAdminService/EemAdmin page to get information about connected SMDAgents allowing an attacker to send HTTP requests (SSRF) and execute OS commands on the connected SMDAgent. Works stable in connected SMDAgent with Java version 1.8. Successful exploitation will allow unauthenticated remote attackers to get a reverse shell from connected to the SolMan agent as the user under which it runs SMDAgent service, which is usually daaadm.
0d5122d6fb0ba7f681b7229fc5c197780b51710c6395404115ad8686072b2b08A vulnerability exists within win32k that can be leveraged by an attacker to escalate privileges to those of NT AUTHORITY\SYSTEM.

ed073b3c17d4f49ffa13834abab3bf326257f8e012a4c37b26486bc312e9e80dThis 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.
88e1248d5e21e3a00dd23e98ab5d2075610af6a2f071e96ac3de2656c5624198This Metasploit module exploits a vulnerability in cldflt.sys. The Cloud Filter driver on Windows 10 v1803 and later, prior to the December 2020 updates, did not set the IO_FORCE_ACCESS_CHECK or OBJ_FORCE_ACCESS_CHECK flags when calling FltCreateFileEx() and FltCreateFileEx2() within its HsmpOpCreatePlaceholders() function with attacker controlled input. This meant that files were created with KernelMode permissions, thereby bypassing any security checks that would otherwise prevent a normal user from being able to create files in directories they don't have permissions to create files in. This module abuses this vulnerability to perform a DLL hijacking attack against the Microsoft Storage Spaces SMP service, which grants the attacker code execution as the NETWORK SERVICE user. Users are strongly encouraged to set the PAYLOAD option to one of the Meterpreter payloads, as doing so will allow them to subsequently escalate their new session from NETWORK SERVICE to SYSTEM by using Meterpreter's "getsystem" command to perform RPCSS Named Pipe Impersonation and impersonate the SYSTEM user.
5bdffeb4ef0091f8099814e9f3a61b1346960497efc651c7566901fb62b98d96This Metasploit module exploits CVE-2020-1054, an out of bounds write reachable from DrawIconEx within win32k. The out of bounds write can be used to overwrite the pvbits of a SURFOBJ. By utilizing this vulnerability to execute controlled writes to kernel memory, an attacker can gain arbitrary code execution as the SYSTEM user. This module has been tested against a fully updated Windows 7 x64 SP1. Offsets within the exploit code may need to be adjusted to work with other versions of Windows.
868acae66ad56703c17e3c65ef2f0fd90bad10c8ec6f9816219080fe42106f93This Metasploit module exploits CVE-2019-1458, an arbitrary pointer dereference vulnerability within win32k which occurs due to an uninitialized variable, which allows user mode attackers to write a limited amount of controlled data to an attacker controlled address in kernel memory. By utilizing this vulnerability to execute controlled writes to kernel memory, an attacker can gain arbitrary code execution as the SYSTEM user. This module has been tested against Windows 7 x64 SP1. Offsets within the exploit code may need to be adjusted to work with other versions of Windows. The exploit can only be triggered once against the target and can cause the target machine to reboot when the session is terminated.
965825e462e62b73a8b4edd4aeb9b9d17c52ab810644e44a21ae2613d7a92025This Metasploit module exploit uses access to the UniversalOrchestrator ScheduleWork API call which does not verify the caller's token before scheduling a job to be run as SYSTEM. You cannot schedule something in a given time, so the payload will execute as system sometime in the next 24 hours.
