New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 2.5


The remote Apache Tomcat server is affected by a denial of service vulnerability.


According to its self-reported version number, the Apache Tomcat server running on the remote host is 6.0.x prior to version 6.0.42. It is, therefore, affected by a flaw in 'ChunkedInputFilter.java' due to improper handling of attempts to continue reading data after an error has occurred. A remote attacker, using streaming data with malformed chunked transfer coding, can exploit this to conduct HTTP request smuggling or cause a denial of service.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.


Update to Apache Tomcat version 6.0.43 or later.

Note that while version 6.0.42 fixes the issue, it was not officially released, and the vendor recommends upgrading to 6.0.43 or later.
