Denial of Service (DoS)

org.apache.tomcat:tomcat-coyote is a Tomcat Connectors and HTTP parser.

Affected versions of this package are vulnerable to Denial of Service (DoS) in the implementation of the HTTP/2 protocol. An attacker can cause a denial of service (including via DDoS) by rapidly resetting many streams through request cancellation.

How to fix Denial of Service (DoS)?

Upgrade org.apache.tomcat:tomcat-coyote to version 8.5.94, 9.0.81, 10.1.14, 11.0.0-M12 or higher.

  • H
Denial of Service (DoS)

org.apache.tomcat:tomcat-coyote is a Tomcat Connectors and HTTP parser.

Affected versions of this package are vulnerable to Denial of Service (DoS). When Tomcat is configured to use NIO+OpenSSL or NIO2+OpenSSL for TLS, a specially-crafted packet could be used to trigger an infinite loop resulting in a denial of service.

How to fix Denial of Service (DoS)?

Upgrade org.apache.tomcat:tomcat-coyote to version 10.0.4, 8.5.64, 9.0.44 or higher.

Arbitrary File Upload

org.apache.tomcat:tomcat-coyote is a Tomcat Connectors and HTTP parser.

Affected versions of this package are vulnerable to Arbitrary File Upload. This is enabled by default with a default configuration port of 8009. A remote, unauthenticated attacker could exploit this vulnerability to read web application files from a vulnerable server. In instances where the vulnerable server allows file uploads, an attacker could upload malicious JavaServer Pages (JSP) code within a variety of file types and trigger this vulnerability to gain remote code execution (RCE).

How to fix Arbitrary File Upload?

Upgrade org.apache.tomcat:tomcat-coyote to version 9.0.31, 8.5.51, 7.0.100 or higher.

Information Exposure

org.apache.tomcat:tomcat-coyote A bug in the handling of the pipelined requests in Apache Tomcat 9.0.0.M1 to 9.0.0.M18, 8.5.0 to 8.5.12, 8.0.0.RC1 to 8.0.42, 7.0.0 to 7.0.76, and 6.0.0 to 6.0.52, when send file was used, results in the pipelined request being lost when send file processing of the previous request completed. This could result in responses appearing to be sent for the wrong request. For example, a user agent that sent requests A, B and C could see the correct response for request A, the response for request C for request B and no response for request C.

[7.0.0,7.0.77) [8,8.0.43) [8.5.0,8.5.13) [9-alpha,9.0.0.M19)
  • H
Information Exposure

org.apache.tomcat:tomcat-coyote is a Tomcat Connectors and HTTP parser.

Affected versions of this package are vulnerable to Information Exposure. The code that parsed the HTTP request line permitted invalid characters. This could be exploited, in conjunction with a proxy that also permitted the invalid characters but with a different interpretation, to inject data into the HTTP response. By manipulating the HTTP response the attacker could poison a web-cache, perform an XSS attack and/or obtain sensitive information from requests other then their own.

How to fix Information Exposure?

Upgrade org.apache.tomcat:tomcat-coyote to version 7.0.73, 8.0.39, 8.5.8, 9.0.0.M13 or higher.
