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.

Denial of Service (DoS)

org.apache.tomcat:tomcat-coyote It was discovered that a programming error in the processing of HTTPS requests in the Apache Tomcat servlet and JSP engine may result in denial of service via an infinite loop. The denial of service is easily achievable as a consequence of backporting a CVE-2016-6816 fix but not backporting the fix for Tomcat bug 57544. Distributions affected by this backporting issue include Debian (before 7.0.56-3+deb8u8 and 8.0.14-1+deb8u7 in jessie) and Ubuntu.

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.

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.

Information Exposure

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

Affected versions of this package are vulnerable to Information Exposure. Apache Tomcat 6.0.30 through 6.0.33 and 7.x before 7.0.22 does not properly perform certain caching and recycling operations involving request objects, which allows remote attackers to obtain unintended read access to IP address and HTTP header information in opportunistic circumstances by reading TCP data.

How to fix Information Exposure?

Upgrade org.apache.tomcat:tomcat-coyote to version 7.0.22 or higher.

Improper Input Validation

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

Affected versions of this package are vulnerable to Improper Input Validation. When sendfile is enabled for the HTTP APR or HTTP NIO connector, does not validate certain request attributes, which allows local users to bypass intended file access restrictions or cause a denial of service (infinite loop or JVM crash) by leveraging an untrusted web application.

How to fix Improper Input Validation?

Upgrade org.apache.tomcat:tomcat-coyote to version 7.0.19 or higher.

  • M
Information Exposure

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

Affected versions of this package are vulnerable to Information Exposure. Apache Tomcat before 6.0.39, 7.x before 7.0.47, and 8.x before 8.0.0-RC3, when an HTTP connector or AJP connector is used, does not properly handle certain inconsistent HTTP request headers, which allows remote attackers to trigger incorrect identification of a request's length and conduct request-smuggling attacks via (1) multiple Content-Length headers or (2) a Content-Length header and a "Transfer-Encoding: chunked" header.

NOTE: this vulnerability exists because of an incomplete fix for CVE-2005-2090.
