Metasploit Weekly Wrap-Up
This week’s Metasploit Framework release brings us seven new modules.
IP Camera Exploitation
Rapid7’s Jacob Baines [https://github.com/jbaines-r7] was busy this week with
two exploit modules that target IP cameras. The first
[https://github.com/rapid7/metasploit-framework/pull/16190] module exploits an
authenticated file upload on Axis IP cameras. Due to lack of proper
sanitization, an attacker can upload and install an eap application which, when
executed, will grant the attacker root privileg

Word and Javascript are a rare duo.
Thanks to thesunRider [https://github.com/thesunRider]. you too can experience
the wonder of this mystical duo. The sole new metasploit module this release
adds a file format attack to generate a very special document. By utilizing
Javascript embedded in a Word document to trigger a chain of events that slip
through various Windows facilities, a session as the user who opened the
document can be yours.

Self-Service Remote Code Execution
This week, our own @wvu-r7 [https://github.com/wvu-r7] added an exploit module
[https://github.com/rapid7/metasploit-framework/pull/15874] that achieves
unauthenticated remote code execution in ManageEngine ADSelfService Plus, a
self-service password management and single sign-on solution for Active

scanner module for Azure Active Directory

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
