Apache Tomcat Transfer-Encoding Information Disclosure and DoS
Apache Tomcat 5.5.0 through 5.5.29, 6.0.0 through 6.0.27, and 7.0.0 beta does not properly handle an invalid Transfer-Encoding header, which allows remote attackers to cause a denial of service (application outage) or obtain sensitive information via a crafted header that interferes with "recycling of a buffer."
Module type : auxiliary Rank : normal
Slowloris Denial of Service Attack
Slowloris tries to keep many connections to the target web server open and hold them open as long as possible. It accomplishes this by opening connections to the target web server and sending a partial request. Periodically, it will send subsequent HTTP headers, adding to-but never completing-the request. Affected servers will keep these connections open, filling their maximum concurrent connection pool, eventually denying additional connection attempts from clients.
