Microsoft Exchange ProxyNotShell Remote Code Execution
Posted Nov 30, 2022
Authored by Soroush Dalili, Spencer McIntyre, Orange Tsai, Rich Warren, Piotr B, DA-0x43-Dx4-DA-Hx2-Tx2-TP-S-Q | Site metasploit.com

This Metasploit module chains two vulnerabilities on Microsoft Exchange Server that, when combined, allow an authenticated attacker to interact with the Exchange Powershell backend (CVE-2022-41040), where a deserialization flaw can be leveraged to obtain code execution (CVE-2022-41082). This exploit only supports Exchange Server 2019. These vulnerabilities were patched in November 2022.

WSO Arbitrary File Upload / Remote Code Execution
Posted May 2, 2022
Authored by Orange Tsai, wvu, hakivvi, Jack Heysel | Site metasploit.com

This Metasploit module abuses a vulnerability in certain WSO2 products that allow unrestricted file upload with resultant remote code execution. This affects WSO2 API Manager 2.2.0 and above through 4.0.0; WSO2 Identity Server 5.2.0 and above through 5.11.0; WSO2 Identity Server Analytics 5.4.0, 5.4.1, 5.5.0, and 5.6.0; WSO2 Identity Server as Key Manager 5.3.0 and above through 5.10.0; and WSO2 Enterprise Integrator 6.2.0 and above through 6.6.0.

Samba VFS Heap Out-Of-Bounds Read / Write
Posted Feb 2, 2022
Authored by Orange Tsai | Site samba.org

All versions of Samba prior to 4.13.17 are vulnerable to an out-of-bounds heap read write vulnerability that allows remote attackers to execute arbitrary code as root on affected Samba installations that use the VFS module vfs_fruit.

Microsoft Exchange ProxyShell Remote Code Execution
Posted Aug 20, 2021
Authored by Spencer McIntyre, Orange Tsai, wvu, Ramella Sebastien, Jang, PeterJson, brandonshi123 | Site metasploit.com

This Metasploit module exploits a vulnerability on Microsoft Exchange Server that allows an attacker to bypass the authentication, impersonate an arbitrary user, and write an arbitrary file to achieve remote code execution. By taking advantage of this vulnerability, you can execute arbitrary commands on the remote Microsoft Exchange Server. This vulnerability affects Exchange 2013 CU23 versions before 15.0.1497.15, Exchange 2016 CU19 versions before 15.1.2176.12, Exchange 2016 CU20 versions before 15.1.2242.5, Exchange 2019 CU8 versions before 15.2.792.13, and Exchange 2019 CU9 versions before 15.2.858.9.

Microsoft Exchange ProxyLogon Remote Code Execution
Posted Mar 23, 2021
Authored by Orange Tsai, mekhalleh, Jang, lotusdll | Site metasploit.com

This Metasploit module exploits a vulnerability on Microsoft Exchange Server that allows an attacker bypassing the authentication, impersonating as the admin (CVE-2021-26855) and write arbitrary file (CVE-2021-27065) to get the RCE (Remote Code Execution). By taking advantage of this vulnerability, you can execute arbitrary commands on the remote Microsoft Exchange Server. This vulnerability affects Exchange 2013 Versions less than 15.00.1497.012, Exchange 2016 CU18 less than 15.01.2106.013, Exchange 2016 CU19 less than 15.01.2176.009, Exchange 2019 CU7 less than 15.02.0721.013, and Exchange 2019 CU8 less than 15.02.0792.010. All components are vulnerable by default.

Pulse Secure VPN Arbitrary Command Execution
Posted Nov 12, 2019
Authored by Orange Tsai, wvu, Meh Chang | Site metasploit.com

This Metasploit module exploits a post-auth command injection in the Pulse Secure VPN server to execute commands as root. The env(1) command is used to bypass application whitelisting and run arbitrary commands. Please see related module auxiliary/gather/pulse_secure_file_disclosure for a pre-auth file read that is able to obtain plaintext and hashed credentials, plus session IDs that may be used with this exploit. A valid administrator session ID is required in lieu of untested SSRF.

Jenkins ACL Bypass / Metaprogramming Remote Code Execution
Posted Mar 19, 2019
Authored by Orange Tsai, wvu | Site metasploit.com

This Metasploit module exploits a vulnerability in Jenkins dynamic routing to bypass the Overall/Read ACL and leverage Groovy metaprogramming to download and execute a malicious JAR file. The ACL bypass gadget is specific to Jenkins versions 2.137 and below and will not work on later versions of Jenkins. Tested against Jenkins 2.137 and Pipeline: Groovy Plugin 2.61.

MS13-055 Microsoft Internet Explorer CAnchorElement Use-After-Free
Posted Sep 9, 2013
Authored by Peter Vreugdenhil, sinn3r, Orange Tsai | Site metasploit.com

In IE8 standards mode, it's possible to cause a use-after-free condition by first creating an illogical table tree, where a CPhraseElement comes after CTableRow, with the final node being a sub table element. When the CPhraseElement's outer content is reset by using either outerText or outerHTML through an event handler, this triggers a free of its child element (in this case, a CAnchorElement, but some other objects apply too), but a reference is still kept in function SRunPointer::SpanQualifier. This function will then pass on the invalid reference to the next functions, eventually used in mshtml!CElement::Doc when it's trying to make a call to the object's SecurityContext virtual function at offset +0x70, which results a crash. An attacker can take advantage of this by first creating an CAnchorElement object, let it free, and then replace the freed memory with another fake object. Successfully doing so may allow arbitrary code execution under the context of the user. This bug is specific to Internet Explorer 8 only. It was originally discovered by Orange Tsai at Hitcon 2013, but was silently patched in the July 2013 update.
