Pre-authenticated Remote Code Execution in VMware NSX Manager using XStream (CVE-2021-39144) There’s nothing quite like a pre-authenticated remote code execution vulnerability in a piece of enterprise software. This week, community contributor h00die-gr3y [https://github.com/h00die-gr3y] added a module [https://github.com/rapid7/metasploit-framework/pull/17222] that targets VMware NSX Manager using XStream. Due to an unauthenticated endpoint that leverages XStream for input serialization in VMwa

Zimbra with Postfix LPE (CVE-2022-3569) This week rbowes [https://github.com/rbowes-r7] added an LPE exploit for Zimbra with Postfix. The exploit leverages a vulnerability whereby the Zimbra user can run postfix as root which in turn is capable of executing arbitrary shellscripts. This can be abused for reliable privilege escalation from the context of the zimbra service account to root. As of this time, this vulnerability remains unpatched.

Roxy-WI Unauthenticated RCE This week, community member Nuri Çilengir [https://github.com/ncilengir] added an unauthenticated RCE for Roxy-WI. Roxy-WI is an interface for managing HAProxy, Nginx and Keepalived servers. The vulnerability can be triggered by a specially crafted POST request to a Python script where the ipbackend parameter is vulnerable to OS command injection. The result is reliable code execution within the context of the web application user. Fewer Meterpreter Scripts Community

Meterpreter Debugging A consistent message Metasploit hears from users is that debugging and general logging support could be improved. The gaps in functionality make it difficult for users to understand what happens when things go wrong and for new and existing developers to fix bugs and add new features. The Metasploit team has been trying to improve this in various parts of the framework, the most recent being Meterpreter. Meterpreter payloads now have additional debugging options that can be

Capture Plugin Capturing credentials is a critical and early phase in the playbook of many offensive security testers. Metasploit has facilitated this for years with protocol-specific modules all under the auxiliary/server/capture. Users can start and configure each of these modules individually, but now the capture plugin can streamline the process. The capture plugin can easily start 13 different services (17 including SSL enabled versions) on the same listening IP address including remote int

Exchange RCE Exchange remote code execution vulnerabilities are always valuable exploits to have. This week Metasploit added an exploit for an authenticated RCE in Microsoft Exchange servers 2016 and server 2019 identified as CVE-2021-42321 [https://attackerkb.com/topics/4JMe2Y1WSY/cve-2021-42321?referrer=blog]. The flaw leveraged by the exploit exists in a misconfigured denylist that failed to prevent a serialized blob from being loaded resulting in code execution. While this is an authenticate

GitLab RCE New Rapid7 team member jbaines-r7 [https://github.com/jbaines-r7] wrote an exploit targeting GitLab via the ExifTool command. Exploiting this vulnerability results in unauthenticated remote code execution as the git user. What makes this module extra neat is the fact that it chains two vulnerabilities together to achieve this desired effect. The first vulnerability is in GitLab itself that can be leveraged to pass invalid image files to the ExifTool parser which contained the second v

NSClient++ Community contributor Yann Castel has contributed an exploit module for NSClient++ which targets an authenticated command execution vulnerability. Users that are able to authenticate to the service as admin can leverage the external scripts feature to execute commands with SYSTEM level privileges. This allows the underlying server to be compromised. Castel is also working on another exploit module for NSClient++ which happens to be a local privilege escalation so stay tuned for more N
