Here's what that rule is looking for:On any port of any host designated as a SQL SERVER (in the var in your snort.conf file)
content:"|05|"; depth:1; byte_test:2,>,512,1; content:"|3B|"; distance:0; isdataat:512,relative; content:!"|3B|"; within:512;
Which translates to:Enqueue followed by ";" between 2 and 512 bytes later followed by another ";" within 512 bytes of the previous one with data in between the semicolons. Engueuing is the process of putting items in a queue, which is frequently used in databases.
Can you post the payload?If you have sql servers on your network, you should define them in the SQL_SERVERS var in snort.conf. That will eliminate useless alerts like this one.

Hi Folks; I’m quite new to snort. I have a user using Win Media Player to listen to streaming radio from WIMZ out of Knoxville, TN. My issue is that it is causing snort to go crazy. I've received over 100 of the following messages: IDS:S=snort:ID=1:[1:2329:6] MS-SQL probe response overflow attempt [Classification: Attempted User Privilege Gain] [Priority: 1]: {UDP} 66.250.188.37:2267 -> 10.88.220.65:1215 My user's ip is 65 and when I had her stop accessing the stream the messages stopped? What is up with this? I have no SQL services running on her computer? Thanks for your help!
