CVE-2008-4678 describes a denial-of-service vulnerability in IBM WebSphere Application Server (WAS) versions 6.0.2 prior to 6.0.2.31. A remote attacker can exploit this flaw by sending a crafted HTTP request with an excessively long Host header, leading to a controller 0C4 abend and application hang due to a storage overlay on the stack during HTTP_Request_Parser method processing. This vulnerability carries a high severity CVSS score of 7.8, indicating a network-based attack with low complexity that can result in a complete denial of service.
