Apache Tomcat Hash Collision Denial Of Service Vulnerability
危険度: 中
CVE識別番号: CVE-2011-4858,CVE-2011-4084
情報公開日: 7 21, 2015
概要
Apache Tomcat before 5.5.35, 6.x before 6.0.35, and 7.x before 7.0.23 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.
