CVE-2023-21554 - QueueJumper - MSMQ RCE Check
This module checks the provided hosts for the CVE-2023-21554 vulnerability by sending a MSMQ message with an altered DataLength field within the SRMPEnvelopeHeader that overflows the given buffer. On patched systems, the error is caught and no response is sent back. On vulnerable systems, the integer wraps around and depending on the length could cause an out-of-bounds write. In the context of this module a response is sent back, which indicates that the system is vulnerable.

Microsoft: December security updates cause Message Queuing failures
## Microsoft: December security updates cause Message Queuing failures
## Sergiu Gatlan
Microsoft has confirmed that the December 2025 security updates are breaking Message Queuing (MSMQ) functionality, affecting enterprise applications and Internet Information Services (IIS) websites.
This known issue affects Windows 10 22H2, Windows Server 2019, and Windows Server 2016 systems that have installed the KB5071546 , KB5071544 , and KB5071543 security updates released during this month's Patch Tuesday.
On impacted systems, users are experiencing a wide range of symptoms, from inactive MSMQ queues and IIS sites failing with "insufficient resources" errors to applications unable to write to queues. Some systems are also displaying misleading "There is insufficient disk space or memory," des
