I've seen the same here.

Here´s what snort get from the probes.

Mar 20 02:55:05 snort: WEB-CGI-TEST-CGIprobe!: 128.175.13.74:48153 ->
x.x.x.x:80
Mar 20 05:15:55 snort: WEB-CGI-PHF CGI access attempt:
128.175.13.74:59064 -> x.x.x.x:80
Mar 20 06:11:25 snort: WEB-CGI-Aglimpse CGI access attempt:
128.175.13.74:58311 -> x.x.x.x:80
Mar 21 05:41:16 snort: WEB-CGI-sh: 128.175.13.74:57899 -> x.x.x.x:80
Mar 21 06:25:26 snort: WEB-CGI-query: 128.175.13.74:34372 -> x.x.x.x:80

I've compared this with the web server logs and my snort rulebase only
missed a couple probes (counterfiglet and perl).
