tomcat: Information leak between requests on the same connection

An information disclosure issue was discovered in Apache Tomcat 8.5.7 to 8.5.9 and 9.0.0.M11 to 9.0.0.M15 in reverse-proxy configurations. Http11InputBuffer.java allows remote attackers to read data that was intended to be associated with a different request.

Apache Tomcat: Security constraint bypass with HTTP/0.9

Improper Input Validation vulnerability in Apache Tomcat. Tomcat did not limit HTTP/0.9 requests to the GET method. If a security constraint was configured to allow HEAD requests to a URI but deny GET requests, the user could bypass that constraint on GET requests by sending a (specification invalid) HEAD request using HTTP/0.9. This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.14, from 10.1.0-M1 through 10.1.49, from 9.0.0.M1 through 9.0.112. Older, EOL versions are also affected. Users are recommended to upgrade to version 11.0.15 or later, 10.1.50 or later or 9.0.113 or later, which fixes the issue.

Apache Tomcat Native, Apache Tomcat: OCSP revocation bypass

Improper Input Validation vulnerability in Apache Tomcat Native, Apache Tomcat. When using an OCSP responder, Tomcat Native (and Tomcat's FFM port of the Tomcat Native code) did not complete verification or freshness checks on the OCSP response which could allow certificate revocation to be bypassed. This issue affects Apache Tomcat Native:  from 1.3.0 through 1.3.4, from 2.0.0 through 2.0.11; Apache Tomcat: from 11.0.0-M1 through 11.0.17, from 10.1.0-M7 through 10.1.51, from 9.0.83 through 9.0.114. The following versions were EOL at the time the CVE was created but are known to be affected: from 1.1.23 through 1.1.34, from 1.2.0 through 1.2.39. Older EOL versions are not affected. Apache Tomcat Native users are recommended to upgrade to versions 1.3.5 or later or 2.0.12 or later, which fix the issue. Apache Tomcat users are recommended to upgrade to versions 11.0.18 or later, 10.1.52 or later or 9.0.115 or later which fix the issue.

Apache Tomcat may be started without proper security settings if errors are encountered while reading the web.xml file, which could allow attackers to bypass intended restrictions.

The default configuration of Jakarta Tomcat does not restrict access to the /admin context, which allows remote attackers to read arbitrary files by directly calling the administrative servlets to add a context for the root directory.

Jakarta Tomcat 3.1 under Apache reveals physical path information when a remote attacker requests a URL that does not exist, which generates an error message that includes the physical path.

The Snoop servlet in Jakarta Tomcat 3.1 and 3.0 under Apache reveals sensitive system information when a remote attacker requests a nonexistent URL with a .snp extension.

Jakarta Tomcat before 3.3.1a on certain Windows systems may allow remote attackers to cause a denial of service (thread hang and resource consumption) via a request for a JSP page containing an MS-DOS device name, such as aux.jsp.

The Catalina org.apache.catalina.connector.http package in Tomcat 4.0.x up to 4.0.3 allows remote attackers to cause a denial of service via several requests that do not follow the HTTP protocol, which causes Tomcat to reject later requests.

Apache Tomcat before 5.x allows remote attackers to cause a denial of service (application crash) via a crafted AJP12 packet to TCP port 8007.

tomcat multiple content-length header poisioning

Jakarta Tomcat 5.0.19 (Coyote/1.1) and Tomcat 4.1.24 (Coyote/1.0) allows remote attackers to poison the web cache, bypass web application firewall protection, and conduct XSS attacks via an HTTP request with both a "Transfer-Encoding: chunked" header and a Content-Length header, which causes Tomcat to incorrectly handle and forward the body of the request in a way that causes the receiving server to process it as a separate HTTP request, aka "HTTP Request Smuggling."

The AJP connector in Apache Tomcat 4.0.1 through 4.0.6 and 4.1.0 through 4.1.36, as used in Hitachi Cosminexus Application Server and standalone, does not properly handle when a connection is broken before request body data is sent in a POST request, which can lead to an information leak when "unsuitable request body data" is used for a different request, possibly related to Java Servlet pages.

tomcat DoS

Apache Tomcat 5.5.0 to 5.5.11 allows remote attackers to cause a denial of service (CPU consumption) via a large number of simultaneous requests to list a web directory that has a large number of files.

Apache Tomcat 4.0.3, when running on Windows, allows remote attackers to obtain sensitive information via a request for a file that contains an MS-DOS device name such as lpt9, which leaks the pathname in an error message, as demonstrated by lpt9.xtp using Nikto.

The HTTP/1.1 connector in Apache Tomcat 4.1.15 through 4.1.40 does not reject NULL bytes in a URL when allowLinking is configured, which allows remote attackers to read JSP source files and obtain sensitive information.

tomcat manager example DoS

Multiple cross-site scripting (XSS) vulnerabilities in the example web applications for Jakarta Tomcat 5.5.6 and earlier allow remote attackers to inject arbitrary web script or HTML via (1) el/functions.jsp, (2) el/implicit-objects.jsp, and (3) jspx/textRotate.jspx in examples/jsp2/, as demonstrated via script in a request to snp/snoop.jsp. NOTE: other XSS issues in the manager were simultaneously reported, but these require admin access and do not cross privilege boundaries.

tomcat directory listing issue

Apache Tomcat 5 before 5.5.17 allows remote attackers to list directories via a semicolon (;) preceding a filename with a mapped extension, as demonstrated by URLs ending with /;index.jsp and /;help.do.

Directory traversal vulnerability in source.jsp of Apache Tomcat before 3.1 allows remote attackers to read arbitrary files via a .. (dot dot) in the argument to source.jsp.

Apache Software Foundation Tomcat Servlet prior to 3.2.2 allows a remote attacker to read the source code to arbitrary 'jsp' files via a malformed URL request which does not end with an HTTP protocol specification (i.e. HTTP/1.0).

A cross-site scripting vulnerability in Apache Tomcat 3.2.1 allows a malicious webmaster to embed Javascript in a request for a .JSP file, which causes the Javascript to be inserted into an error message.
