| # MSMQCheck | ||
|
|
||
| MSMQCheck is a security analysis tool for [Microsoft Message Queuing (MSMQ)](https://en.wikipedia.org/wiki/Microsoft_Message_Queuing). It dumps security information about each queue on the local system and generates a summary report. | ||
|
|
||
| The following issues are currently reported: | ||
|
|
||
| - **Queues with authentication disabled.** When authentication is disabled, the access control list (ACL) is ignored and everyone has full access to the queue. | ||
| - **Queues owned by ANONYMOUS LOGON or Guest.** Queues owned by these accounts are insecure, for obvious reasons. | ||
| - **Queues accessible via multicast addresses.** Multicast accessible queues are not inherently secure, but it is important to identify queues that are accessible via multicast due to the potential for evading firewall rules or accessing queues when the direct TCP/OS endpoints are disabled. | ||
| - **Queues with encryption disabled/optional.** Disabled means that encrypted connections are not supported, even if the client requests it. Optional means that unencrypted connections are allowed, and this is the default. | ||
| - **Queues that allow messages to be written by ANONYMOUS LOGON.** This allows anyone on the network to write messages to the queue. | ||
| - **Queues that allow messages to be received or peeked by ANONYMOUS LOGON.** This allows anyone on the network to read messages from the queue. | ||
| - **Queues that allow for queue properties to be modified by ANONYMOUS LOGON.** This allows anyone on the network to change the properties (either the queue properties or ACL) of the queue. | ||
| - **Queues that allow messages to be written by Everyone / Authenticated Users / Domain Users.** This allows anyone with a valid user account to write messages to the queue. | ||
| - **Queues that allow messages to be received or peeked by Everyone / Authenticated Users / Domain Users.** This allows anyone with a valid user account to read messages from the queue. | ||
| - **Queues that allow for queue properties to be modified by Everyone / Authenticated Users / Domain Users.** This allows anyone with a valid user account to change the properties (either the queue properties or ACL) of the queue. | ||
|
|
||
| For completeness, ACL issues are reported regardless of whether authentication is enabled. Just keep in mind that if authentication is disabled then it doesn't matter what the ACL says. | ||
|
|

||
| ## Troubleshooting | ||
|
|
||
| ### Failed to get queue names | ||
|
|
||
| If you receive the error `Failed to get queue names. Exception: Invalid class`, this means you don't have MSMQ installed on the local system. MSMQCheck should be executed on the server that hosts the queues, not on a client system that accesses the queues remotely. | ||
|
|
||
| ### MQGetQueueProperties call failed | ||
|
|
||
| When enumerating the MSMQ queues on the local system, the results include remote queues that are currently connected or have pending messages. MSMQCheck will attempt to query these remote queues, but in general you'll see this error when it tries. This is either because the protocol being used doesn't support this type of query (e.g. HTTP) or you don't have the rights to access queue information remotely. To get information about these queues, run MSMQCheck on the system that hosts them. | ||
|
|
||
| The local system may also include results such as "Computer Queues" or queues ending in `$`, at the end of the list. These are pretty much guaranteed to throw errors when MSMQCheck tries to query them. These are not normal queues and can generally be ignored. | ||
