Summary

java/org/apache/coyote/http11/filters/ChunkedInputFilter.java in Apache Tomcat 6.x before 6.0.42, 7.x before 7.0.55, and 8.x before 8.0.9 does not properly handle attempts to continue reading data after an error has occurred, which allows remote attackers to conduct HTTP request smuggling attacks or cause a denial of service (resource consumption) by streaming data with malformed chunked transfer coding.

Risk Assessment

An attacker could smuggle HTTP requests, bypassing security mechanisms, or exhaust server resources, leading to service unavailability.

Recommendation

Update Apache Tomcat to version 6.0.42, 7.0.55, 8.0.9 or later.
