Poly Systems - Tomcat Denial of Service Impact

Vulnerability Summary

Apache Tomcat 6.x before 6.0.44, 7.x before 7.0.55, and 8.x before 8.0.9 does not properly handle cases where an HTTP response occurs before finishing the reading of an entire request body, which allows remote attackers to cause a denial of service (memory consumption) via a series of aborted upload attempts. 

 

Details

CVE-2014-0230

Apache Tomcat 6.x before 6.0.44, 7.x before 7.0.55, and 8.x before 8.0.9 does not properly handle cases where an HTTP response occurs before finishing the reading of an entire request body, which allows remote attackers to cause a denial of service (thread consumption) via a series of aborted upload attempts.

From Apache Tomcat: 

“When a response for a request with a request body is returned to the user agent before the request body is fully read, by default Tomcat swallows the remaining request body so that the next request on the connection may be processed. There was no limit to the size of request body that Tomcat would swallow. This permitted a limited Denial of Service as Tomcat would never close the connection and a processing thread would remain allocated to the connection.”
