DescriptionNVD

IBM WebSphere Application Server 9.0, and 8.5 is vulnerable to a denial of service, caused by sending a specially-crafted request. A remote attacker could exploit this vulnerability to trigger excessive resource consumption, potentially leading to reduced availability of the affected service.

AnalysisAI

Remote denial-of-service in IBM WebSphere Application Server 8.5 and 9.0 allows an unauthenticated network attacker to degrade service availability by sending a specially crafted request that triggers uncontrolled resource consumption (CWE-400). The CVSS A:L metric indicates partial rather than complete service disruption, limiting but not eliminating operational impact. …
