Title
Apache Tomcat Native, Apache Tomcat: OCSP revocation bypass
Summary
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.

Title
Apache Tomcat: Security constraint bypass with HTTP/0.9
Summary
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.

Title
Apache Tomcat: Client certificate verification bypass due to virtual host mapping
Summary
Improper Input Validation vulnerability.
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.
The following versions were EOL at the time the CVE was created but are
known to be affected: 8.5.0 through 8.5.100. Older EOL versions are not affected.
Tomcat did not validate that the host name provided via the SNI
extension was the same as the host name provided in the HTTP host header
field. If Tomcat was configured with more than one virtual host and the
TLS configuration for one of those hosts did not require client
certificate authentication but another one did, it was possible for a
client to bypass the client certificate authentication by sending
different host names in the SNI extension and the HTTP host header field.
The vulnerability only applies if client certificate authentication is
only enforced at the Connector. It does not apply if client certificate
authentication is enforced at the web application.
Users are recommended to upgrade to version 11.0.15 or later, 10.1.50 or later or 9.0.113 or later, which fix the issue.

Title
Apache Tomcat: Delayed cleaning of multi-part upload temporary files may lead to DoS
Summary
Improper Resource Shutdown or Release vulnerability in Apache Tomcat.
If an error occurred (including exceeding limits) during the processing of a multipart upload, temporary copies of the uploaded parts written to disc were not cleaned up immediately but left for the garbage collection process to delete. Depending on JVM settings, application memory usage and application load, it was possible that space for the temporary copies of uploaded parts would be filled faster than GC cleared it, leading to a DoS.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.11, from 10.1.0-M1 through 10.1.46, from 9.0.0.M1 through 9.0.109.
The following versions were EOL at the time the CVE was created but are
known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected.
Users are recommended to upgrade to version 11.0.12 or later, 10.1.47 or later or 9.0.110 or later which fixes the issue.

Title
Apache Tomcat: console manipulation via escape sequences in log messages
Summary
Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache Tomcat.
Tomcat did not escape ANSI escape sequences in log messages. If Tomcat was running in a console on a Windows operating system, and the console supported ANSI escape sequences, it was possible for an attacker to use a specially crafted URL to inject ANSI escape sequences to manipulate the console and the clipboard and attempt to trick an administrator into running an attacker controlled command. While no attack vector was found, it may have been possible to mount this attack on other operating systems.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.10, from 10.1.0-M1 through 10.1.44, from 9.0.40 through 9.0.108.
The following versions were EOL at the time the CVE was created but are
known to be affected: 8.5.60 though 8.5.100. Other, older, EOL versions may also be affected.
Users are recommended to upgrade to version 11.0.11 or later, 10.1.45 or later or 9.0.109 or later, which fix the issue.
Severity ?

Title
Apache Tomcat: Directory traversal via rewrite with possible RCE if PUT is enabled
Summary
Relative Path Traversal vulnerability in Apache Tomcat.
The fix for bug 60013 introduced a regression where the rewritten URL was normalized before it was decoded. This introduced the possibility that, for rewrite rules that rewrite query parameters to the URL, an attacker could manipulate the request URI to bypass security constraints including the protection for /WEB-INF/ and /META-INF/. If PUT requests were also enabled then malicious files could be uploaded leading to remote code execution. PUT requests are normally limited to trusted users and it is considered unlikely that PUT requests would be enabled in conjunction with a rewrite that manipulated the URI.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.10, from 10.1.0-M1 through 10.1.44, from 9.0.0.M11 through 9.0.108.
The following versions were EOL at the time the CVE was created but are
known to be affected: 8.5.6 though 8.5.100. Other, older, EOL versions may also be affected.
Users are recommended to upgrade to version 11.0.11 or later, 10.1.45 or later or 9.0.109 or later, which fix the issue.

Title
Apache Tomcat: Security constraint bypass for pre/post-resources
Summary
Authentication Bypass Using an Alternate Path or Channel vulnerability in Apache Tomcat. When using PreResources or PostResources mounted other than at the root of the web application, it was possible to access those resources via an unexpected path. That path was likely not to be protected by the same security constraints as the expected path, allowing those security constraints to be bypassed.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.7, from 10.1.0-M1 through 10.1.41, from 9.0.0.M1 through 9.0.105.
The following versions were EOL at the time the CVE was created but are
known to be affected: 8.5.0 through 8.5.100. Other, older, EOL versions
may also be affected.
Users are recommended to upgrade to version 11.0.8, 10.1.42 or 9.0.106, which fix the issue.
Severity ?

Title
Apache Tomcat Native, Apache Tomcat: OCSP revocation bypass
Summary
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.

Title
Apache Tomcat: Security constraint bypass with HTTP/0.9
Summary
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.

Title
Apache Tomcat: Client certificate verification bypass due to virtual host mapping
Summary
Improper Input Validation vulnerability.
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.
The following versions were EOL at the time the CVE was created but are
known to be affected: 8.5.0 through 8.5.100. Older EOL versions are not affected.
Tomcat did not validate that the host name provided via the SNI
extension was the same as the host name provided in the HTTP host header
field. If Tomcat was configured with more than one virtual host and the
TLS configuration for one of those hosts did not require client
certificate authentication but another one did, it was possible for a
client to bypass the client certificate authentication by sending
different host names in the SNI extension and the HTTP host header field.
The vulnerability only applies if client certificate authentication is
only enforced at the Connector. It does not apply if client certificate
authentication is enforced at the web application.
Users are recommended to upgrade to version 11.0.15 or later, 10.1.50 or later or 9.0.113 or later, which fix the issue.

Title
Apache Tomcat: Delayed cleaning of multi-part upload temporary files may lead to DoS
Summary
Improper Resource Shutdown or Release vulnerability in Apache Tomcat.
If an error occurred (including exceeding limits) during the processing of a multipart upload, temporary copies of the uploaded parts written to disc were not cleaned up immediately but left for the garbage collection process to delete. Depending on JVM settings, application memory usage and application load, it was possible that space for the temporary copies of uploaded parts would be filled faster than GC cleared it, leading to a DoS.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.11, from 10.1.0-M1 through 10.1.46, from 9.0.0.M1 through 9.0.109.
The following versions were EOL at the time the CVE was created but are
known to be affected: 8.5.0 though 8.5.100. Other, older, EOL versions may also be affected.
Users are recommended to upgrade to version 11.0.12 or later, 10.1.47 or later or 9.0.110 or later which fixes the issue.

Title
Apache Tomcat: Directory traversal via rewrite with possible RCE if PUT is enabled
Summary
Relative Path Traversal vulnerability in Apache Tomcat.
The fix for bug 60013 introduced a regression where the rewritten URL was normalized before it was decoded. This introduced the possibility that, for rewrite rules that rewrite query parameters to the URL, an attacker could manipulate the request URI to bypass security constraints including the protection for /WEB-INF/ and /META-INF/. If PUT requests were also enabled then malicious files could be uploaded leading to remote code execution. PUT requests are normally limited to trusted users and it is considered unlikely that PUT requests would be enabled in conjunction with a rewrite that manipulated the URI.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.10, from 10.1.0-M1 through 10.1.44, from 9.0.0.M11 through 9.0.108.
The following versions were EOL at the time the CVE was created but are
known to be affected: 8.5.6 though 8.5.100. Other, older, EOL versions may also be affected.
Users are recommended to upgrade to version 11.0.11 or later, 10.1.45 or later or 9.0.109 or later, which fix the issue.

Title
Apache Tomcat: console manipulation via escape sequences in log messages
Summary
Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache Tomcat.
Tomcat did not escape ANSI escape sequences in log messages. If Tomcat was running in a console on a Windows operating system, and the console supported ANSI escape sequences, it was possible for an attacker to use a specially crafted URL to inject ANSI escape sequences to manipulate the console and the clipboard and attempt to trick an administrator into running an attacker controlled command. While no attack vector was found, it may have been possible to mount this attack on other operating systems.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.10, from 10.1.0-M1 through 10.1.44, from 9.0.40 through 9.0.108.
The following versions were EOL at the time the CVE was created but are
known to be affected: 8.5.60 though 8.5.100. Other, older, EOL versions may also be affected.
Users are recommended to upgrade to version 11.0.11 or later, 10.1.45 or later or 9.0.109 or later, which fix the issue.

Title
Apache Tomcat: Security constraint bypass for pre/post-resources
Summary
Authentication Bypass Using an Alternate Path or Channel vulnerability in Apache Tomcat. When using PreResources or PostResources mounted other than at the root of the web application, it was possible to access those resources via an unexpected path. That path was likely not to be protected by the same security constraints as the expected path, allowing those security constraints to be bypassed.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.7, from 10.1.0-M1 through 10.1.41, from 9.0.0.M1 through 9.0.105.
The following versions were EOL at the time the CVE was created but are
known to be affected: 8.5.0 through 8.5.100. Other, older, EOL versions
may also be affected.
Users are recommended to upgrade to version 11.0.8, 10.1.42 or 9.0.106, which fix the issue.
