Summary

In Apache Tomcat 9.0.0.M1 to 9.0.0.M18 and 8.5.0 to 8.5.12, the refactoring of the HTTP connectors introduced a regression in the send file processing. If the send file processing completed quickly, it was possible for the Processor to be added to the processor cache twice. This could result in the same Processor being used for multiple requests which in turn could lead to unexpected errors and/or response mix-up.

It is, therefore, affected by multiple vulnerabilities : - A flaw exists in the Apache Tomcat component in the handling of pipelined requests when send file processing is used that results in the pipelined request being lost when processing of the previous request has completed, causing responses to be sent for the wrong request. An unauthenticated, remote attacker can exploit this to disclose sensitive information. (CVE-2017-5647) - A flaw exists in the Apache Tomcat component in HTTP connectors when processing send files. If processing completed quickly, it was possible to add the processor to the processor cache twice, which allows the same processor to be used for multiple requests.

    descriptionAccording to its self-reported version number, the Apache Tomcat service running on the remote host is 8.5.x prior to 8.5.13 or 9.0.x prior to 9.0.0.M19. It is therefore affected by multiple vulnerabilities : - A flaw exists in the handling of pipelined requests when send file processing is used that results in the pipelined request being lost when processing of the previous request has completed, causing responses to be sent for the wrong request. An unauthenticated, remote attacker can exploit this to disclose sensitive information. (CVE-2017-5647) - A flaw exists in the handling of HTTP/2 GOAWAY frames for a connection due to streams associated with the connection not being properly closed if the connection was currently waiting for a WINDOW_UPDATE before allowing the application to write more data. Each stream consumes a processing thread in the system. An unauthenticated, remote attacker can exploit this issue, via a series of specially crafted HTTP/2 requests, to consume all available threads, resulting in a denial of service condition. (CVE-2017-5650) - A flaw exists in HTTP connectors when processing send files. If processing completed quickly, it was possible to add the processor to the processor cache twice, which allows the same processor to be used for multiple requests. An unauthenticated, remote attacker can exploit this to disclose sensitive information from other sessions or cause unexpected errors. (CVE-2017-5651) Note that Nessus has not attempted to exploit these issues but has instead relied only on the application
