Exploitation Summary

EIP tracks 2 public exploits for CVE-2011-5035. PoCs published by rgod, Alexander Klink, Julian Waelde, Scott A. Crosby, Dan S. Wallach, Krzysztof Kotowicz, Christian Mehlmauer, including Metasploit module auxiliary/dos/http/hashcollision_dos.

AI-analyzed exploit summary This exploit demonstrates a SQL injection vulnerability in MyBulletinBoard (MyBB) <= 1.1.5 via the CLIENT-IP HTTP header, allowing an attacker to retrieve the admin login key and create a new admin user.

Description

Oracle Glassfish 2.1.1, 3.0.1, and 3.1.1, as used in Communications Server 2.0, Sun Java System Application Server 8.1 and 8.2, and possibly other products, 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, aka Oracle security ticket S0104869.
