Vulnerability Details : CVE-2011-5034

Apache Geronimo 2.2.1 and earlier computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters. NOTE: this might overlap CVE-2011-4461.

- Metasploit Modules Related To CVE-2011-5034

Hashtable Collisions
This module uses a denial-of-service (DoS) condition appearing in a variety of programming languages. This vulnerability occurs when storing multiple values in a hash table and all values have the same hash value. This can cause a web server parsing the POST parameters issued with a request into a hash table to consume hours of CPU with a single HTTP request. Currently, only the hash functions for PHP and Java are implemented. This module was tested with PHP + httpd, Tomcat, Glassfish and Geronimo. It also generates a random payload to bypass some IDS signatures.
