CUPS IPP Attributes LAN Remote Code Execution
Posted Nov 22, 2024
Authored by Spencer McIntyre, RageLtMan, Simone Margaritelli, Ryan Emmons | Site metasploit.com

This Metasploit module exploits vulnerabilities in OpenPrinting CUPS, which is running by default on most Linux distributions. The vulnerabilities allow an attacker on the LAN to advertise a malicious printer that triggers remote code execution when a victim sends a print job to the malicious printer. Successful exploitation requires user interaction, but no CUPS services need to be reachable via accessible ports. Code execution occurs in the context of the lp user. Affected versions are cups-browsed less than or equal to 2.0.1, libcupsfilters versions 2.1b1 and below, libppd versions 2.1b1 and below, and cups-filters versions 2.0.1 and below.

Pyload Remote Code Execution
Posted Nov 18, 2024
Authored by Spencer McIntyre, jheysel-r7 | Site metasploit.com

CVE-2024-28397 is a sandbox escape in js2py versions 0.74 and below. js2py is a popular python package that can evaluate javascript code inside a python interpreter. The vulnerability allows for an attacker to obtain a reference to a python object in the js2py environment enabling them to escape the sandbox, bypass pyimport restrictions and execute arbitrary commands on the host. At the time of this writing no patch has been released and version 0.74 is the latest version of js2py which was released Nov 6, 2022. CVE-2024-39205 is a remote code execution vulnerability in Pyload versions 0.5.0b3.dev85 and below. It is an open-source download manager designed to automate file downloads from various online sources. Pyload is vulnerable because it exposes the vulnerable js2py functionality mentioned above on the /flash/addcrypted2 API endpoint. This endpoint was designed to only accept connections from localhost but by manipulating the HOST header we can bypass this restriction in order to access the API to achieve unauthenticated remote code execution.

Titan FTP Administrative Password Disclosure
Posted Sep 1, 2024
Authored by Spencer McIntyre | Site metasploit.com

On Titan FTP servers prior to version 9.14.1628, an attacker can retrieve the username and password for the administrative XML-RPC interface, which listens on TCP Port 31001 by default, by sending an XML request containing bogus authentication information. After sending this request, the server responds with the legitimate username and password for the service. With this information, an attacker has complete control over the FTP service, which includes the ability to add and remove FTP users, as well as add, remove, and modify available directories and their permissions.

Netlogon Weak Cryptographic Authentication
Posted Aug 31, 2024
Authored by Spencer McIntyre, Tom Tervoort, Dirk-jan Mollema | Site metasploit.com

A vulnerability exists within the Netlogon authentication process where the security properties granted by AES are lost due to an implementation flaw related to the use of a static initialization vector (IV). An attacker can leverage this flaw to target an Active Directory Domain Controller and make repeated authentication attempts using NULL data fields which will succeed every 1 in 256 tries (~0.4%). This Metasploit module leverages the vulnerability to reset the machine account password to an empty string, which will then allow the attacker to authenticate as the machine account. After exploitation, its important to restore this password to its original value. Failure to do so can result in service instability.

AD CS Certificate Template Management
Posted Aug 31, 2024
Authored by Spencer McIntyre, Lee Christensen, Oliver Lyak, Will Schroeder | Site metasploit.com

This Metasploit module can create, read, update, and delete AD CS certificate templates from a Active Directory Domain Controller. The READ, UPDATE, and DELETE actions will write a copy of the certificate template to disk that can be restored using the CREATE or UPDATE actions. The CREATE and UPDATE actions require a certificate template data file to be specified to define the attributes. Template data files are provided to create a template that is vulnerable to ESC1, ESC2, and ESC3. This Metasploit module is capable of exploiting ESC4.

Apache Superset Signed Cookie Privilege Escalation
Posted Aug 31, 2024
Authored by h00die, Spencer McIntyre, Naveen Sunkavally, paradoxis | Site metasploit.com

Apache Superset versions less than or equal to 2.0.0 utilize Flask with a known default secret key which is used to sign HTTP cookies. These cookies can therefore be forged. If a user is able to login to the site, they can decode the cookie, set their user_id to that of an administrator, and re-sign the cookie. This valid cookie can then be used to login as the targeted user and retrieve database credentials saved in Apache Superset.

Misconfigured Certificate Template Finder
Posted Aug 31, 2024
Authored by Spencer McIntyre, Grant Willcox | Site metasploit.com

This Metasploit module allows users to query a LDAP server for vulnerable certificate templates and will print these certificates out in a table along with which attack they are vulnerable to and the SIDs that can be used to enroll in that certificate template. Additionally the module will also print out a list of known certificate servers along with info about which vulnerable certificate templates the certificate server allows enrollment in and which SIDs are authorized to use that certificate server to perform this enrollment operation. Currently the module is capable of checking for certificates that are vulnerable to ESC1, ESC2, ESC3, and ESC13. The module is limited to checking for these techniques due to them being identifiable remotely from a normal user account by analyzing the objects in LDAP.

Telerik Report Server Authentication Bypass / Remote Code Execution
Posted Jun 13, 2024
Authored by unknown, Soroush Dalili, Spencer McIntyre, SinSinology | Site metasploit.com

This Metasploit module chains an authentication bypass vulnerability with a deserialization vulnerability to obtain remote code execution against Telerik Report Server versions 10.0.24.130 and below. The authentication bypass flaw allows an unauthenticated user to create a new user with administrative privileges. The USERNAME datastore option can be used to authenticate with an existing account to prevent the creation of a new one. The deserialization flaw works by uploading a specially crafted report that when loaded will execute an OS command as NT AUTHORITY\SYSTEM. The module will automatically delete the created report but not the account because users are unable to delete themselves.

FortiNet FortiClient EMS 7.2.2 / 7.0.10 SQL Injection / Remote Code Execution
Posted Apr 23, 2024
Authored by Spencer McIntyre, jheysel-r7, James Horseman, Zach Hanley | Site metasploit.com

A remote SQL injection vulnerability exists in FortiNet FortiClient EMS (Endpoint Management Server) versions 7.2.0 through 7.2.2 and 7.0.1 through 7.0.10. FortiClient EMS serves as an endpoint management solution tailored for enterprises, offering a centralized platform for overseeing enrolled endpoints. The SQL injection vulnerability is due to user controller strings which can be sent directly into database queries. FcmDaemon.exe is the main service responsible for communicating with enrolled clients. By default it listens on port 8013 and communicates with FCTDas.exe which is responsible for translating requests and sending them to the database. In the message header of a specific request sent between the two services, the FCTUID parameter is vulnerable to SQL injection. It can be used to enable the xp_cmdshell which can then be used to obtain unauthenticated remote code execution in the context of NT AUTHORITY\SYSTEM. Upgrading to either 7.2.3, 7.0.11 or above is recommended by FortiNet. It should be noted that in order to be vulnerable, at least one endpoint needs to be enrolled / managed by FortiClient EMS for the necessary vulnerable services to be available.

pgAdmin 8.3 Remote Code Execution
Posted Apr 17, 2024
Authored by Spencer McIntyre, Abdel Adim Oisfi, Davide Silvetti | Site metasploit.com

pgAdmin versions 8.3 and below have a path traversal vulnerability within their session management logic that can allow a pickled file to be loaded from an arbitrary location. This can be used to load a malicious, serialized Python object to execute code within the context of the target application. This exploit supports two techniques by which the payload can be loaded, depending on whether or not credentials are specified. If valid credentials are provided, Metasploit will login to pgAdmin and upload a payload object using pgAdmin's file management plugin. Once uploaded, this payload is executed via the path traversal before being deleted using the file management plugin. This technique works for both Linux and Windows targets. If no credentials are provided, Metasploit will start an SMB server and attempt to trigger loading the payload via a UNC path. This technique only works for Windows targets. For Windows 10 v1709 (Redstone 3) and later, it also requires that insecure outbound guest access be enabled. Tested on pgAdmin 8.3 on Linux, 7.7 on Linux, 7.0 on Linux, and 8.3 on Windows. The file management plugin underwent changes in the 6.x versions and therefore, pgAdmin versions below 7.0 cannot utilize the authenticated technique whereby a payload is uploaded.

QNAP QTS / QuTS Hero Unauthenticated Remote Code Execution
Posted Feb 22, 2024
Authored by Spencer McIntyre, jheysel-r7, sfewer-r7 | Site metasploit.com

There exists an unauthenticated command injection vulnerability in the QNAP operating system known as QTS and QuTS hero. QTS is a core part of the firmware for numerous QNAP entry and mid-level Network Attached Storage (NAS) devices, and QuTS hero is a core part of the firmware for numerous QNAP high-end and enterprise NAS devices. The vulnerable endpoint is the quick.cgi component, exposed by the device's web based administration feature. The quick.cgi component is present in an uninitialized QNAP NAS device. This component is intended to be used during either manual or cloud based provisioning of a QNAP NAS device. Once a device has been successfully initialized, the quick.cgi component is disabled on the system. An attacker with network access to an uninitialized QNAP NAS device may perform unauthenticated command injection, allowing the attacker to execute arbitrary commands on the device.

Mirth Connect 4.4.0 Remote Command Execution
Posted Jan 31, 2024
Authored by r00t, Spencer McIntyre, Naveen Sunkavally | Site metasploit.com

A vulnerability exists within Mirth Connect due to its mishandling of deserialized data. This vulnerability can be leveraged by an attacker using a crafted HTTP request to execute OS commands within the context of the target application. The original vulnerability was identified by IHTeam and assigned CVE-2023-37679. Later, researchers from Horizon3.ai determined the patch to be incomplete and published a gadget chain which bypassed the deny list that the original had implemented. This second vulnerability was assigned CVE-2023-43208 and was patched in Mirth Connect version 4.4.1. This Metasploit module has been tested on versions 4.1.1, 4.3.0 and 4.4.0.

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.

PyTorch Model Server Registration / Deserialization Remote Code Execution
Posted Oct 13, 2023
Authored by Spencer McIntyre, Guy Kaplan, Swapneil Kumar Dash, Idan Levcovich, Gal Elbaz | Site metasploit.com

The PyTorch model server contains multiple vulnerabilities that can be chained together to permit an unauthenticated remote attacker arbitrary Java code execution. The first vulnerability is that the management interface is bound to all IP addresses and not just the loop back interface as the documentation suggests. The second vulnerability (CVE-2023-43654) allows attackers with access to the management interface to register MAR model files from arbitrary servers. The third vulnerability is that when an MAR file is loaded, it can contain a YAML configuration file that when deserialized by snakeyaml, can lead to loading an arbitrary Java class.

Apache Superset 2.0.0 Remote Code Execution
Posted Oct 13, 2023
Authored by h00die, Spencer McIntyre, Naveen Sunkavally, paradoxis | Site metasploit.com

Apache Superset versions 2.0.0 and below utilize Flask with a known default secret key which is used to sign HTTP cookies. These cookies can therefore be forged. If a user is able to login to the site, they can decode the cookie, set their user_id to that of an administrator, and re-sign the cookie. This valid cookie can then be used to login as the targeted user. From there the Superset database is mounted, and credentials are pulled. A dashboard is then created. Lastly a pickled python payload can be set for that dashboard within Superset's database which will trigger the remote code execution. An attempt to clean up ALL of the dashboard key values and reset them to their previous values happens during the cleanup phase.
