I am running a WindowsXP on the attacker's side, which also runs the snort monitoring the local network. The target machine is running a windows2000 with an unpatched IIS4.0. The attacks I used are the common unicode attacks. It generates Web-IIS directory traversal attemps alerts and cmd.exe access alerts. I also used the printer remote buffer overflow attack, which generates "printer access" alerts on snort 1.9.1. The results of my attacks include replacing the webpage and opening a shell on port 99. All the three types of attacks are detected in 1.9.1 but none of them are detected on 2.0.2. It seems for me that the snort didn't even load up the web-iis.rules in 2.0.2.
What is the OS and snort version on your snort box? Which IIS attacks did you run? -----Original Message----- From: Yan Zhai [mailto:yzhai () unity ncsu edu] Sent: Friday, October 10, 2003 11:40 AM To: snort-users () lists sourceforge net Subject: [Snort-users] Problem with web-iis rules Hi there, I installed snort on my machine and launched a number of IIS attacks from my machine to another one in the LAN. The other machine is running an unpatched iis4.0 and the attacks are successful. Snort successfully reported the nmap portscans, however, it failed to report the iis attacks. It seems to me that snort just doesn't load up the web-iis rules. Below is my snort.conf, which is the default snort.conf with database output option. Can anyone point out what's the problem with it?
