Currently unrated

Key Information:

Summary

The IBM Web Application Firewall, utilized in the G400 IPS-G400-IB-1 and GX4004 IPS-GX4004-IB-2 appliances with update 31.030, has a vulnerability that inadequately processes query strings containing multiple instances of the same parameter. This weakness allows remote attackers to sidestep the intended intrusion prevention mechanisms. By segmenting a harmful parameter value into substrings, attackers can craft requests that exploit the vulnerability, such as executing a SQL statement split over multiple 'iid' parameters sent to a .aspx file on an IIS web server.
