When responding to new h2c connection requests, Apache Tomcat could duplicate
request headers and a limited amount of request body from one request to
another meaning user A and user B could both see the results of user A's
request.

The fix for CVE-2020-9484 was incomplete. When using a highly unlikely
configuration edge case, the Tomcat instance was still vulnerable to
CVE-2020-9484. Note that both the previously published prerequisites for
CVE-2020-9484 and the previously published non-upgrade mitigations for
CVE-2020-9484 also apply to this issue.

When serving resources from a network location using the NTFS file system it
was possible to bypass security constraints and/or view the source code for
JSPs in some configurations. The root cause was the unexpected behaviour of the
JRE API File.getCanonicalPath() which in turn was caused by the inconsistent
behaviour of the Windows API (FindFirstFileW) in some circumstances.

A flaw was found in the Apache Tomcat, where session persistence in using
PersistenceManager with a FileStore.
If:
a) an attacker is able to control the contents and name of a file on the
server; and
b) the server is configured to use the PersistenceManager with a
FileStore; and
c) the PersistenceManager is configured with
sessionAttributeValueClassNameFilter="null" (the default unless a
SecurityManager is used) or a sufficiently lax filter to allow the
attacker provided object to be deserialized; and
d) the attacker knows the relative file path from the storage location
used by FileStore to the file the attacker has control over;
then, using a specifically crafted request, the attacker will be able to
trigger remote code execution via deserialization of the file under
their control. Note that all of conditions a) to d) must be true for the
attack to succeed.
It affects the version of Apache Tomcat 10 before 10.0.0-M4, Apache Tomcat 9
before 9.0.34, Tomcat 8 before 8.5.54, and Tomcat 7 before 7.0.103.

In Netty before version 4.1.59.Final there is a vulnerability on Unix-like
systems involving an insecure temp file. When netty's multipart decoders are
used local information disclosure can occur via the local system temporary
directory if temporary storing uploads on the disk is enabled. On unix-like
systems, the temporary directory is shared between all user. As such, writing
to this directory using APIs that do not explicitly set the file/directory
permissions can lead to information disclosure. Of note, this does not impact
modern MacOS Operating Systems. The method "File.createTempFile" on unix-like
systems creates a random file, but, by default will create this file with the
permissions "-rw-r--r--". Thus, if sensitive information is written to this
file, other local users can read this information. This is the case in netty's
"AbstractDiskHttpData" is vulnerable. This has been fixed in version
4.1.59.Final. As a workaround, one may specify your own "java.io.tmpdir" when
you start the JVM or use "DefaultHttpDataFactory.setBaseDir(...)" to set the
directory to something that is only readable by the current user.

Netty is an open-source, asynchronous event-driven network application
framework for rapid development of maintainable high performance protocol
servers & clients. In Netty (io.netty:netty-codec-http2) before version
4.1.60.Final there is a vulnerability that enables request smuggling. If a
Content-Length header is present in the original HTTP/2 request, the field is
not validated by `Http2MultiplexHandler` as it is propagated up. This is fine
as long as the request is not proxied through as HTTP/1.1. If the request comes
in as an HTTP/2 stream, gets converted into the HTTP/1.1 domain objects
(`HttpRequest`, `HttpContent`, etc.) via `Http2StreamFrameToHttpObjectCodec
`and then sent up to the child channel's pipeline and proxied through a remote
peer as HTTP/1.1 this may result in request smuggling. In a proxy case, users
may assume the content-length is validated somehow, which is not the case. If
the request is forwarded to a backend channel that is a HTTP/1.1 connection,
the Content-Length now has meaning and needs to be checked. An attacker can
smuggle requests inside the body as it gets downgraded from HTTP/2 to HTTP/1.1.
For an example attack refer to the linked GitHub Advisory. Users are only
affected if all of this is true: `HTTP2MultiplexCodec` or `Http2FrameCodec` is
used, `Http2StreamFrameToHttpObjectCodec` is used to convert to HTTP/1.1
objects, and these HTTP/1.1 objects are forwarded to another remote peer. This
has been patched in 4.1.60.Final As a workaround, the user can do the
validation by themselves by implementing a custom `ChannelInboundHandler` that
is put in the `ChannelPipeline` behind `Http2StreamFrameToHttpObjectCodec`.

request smuggling if the request is proxied to a remote peer and translated to
HTTP/1.1. This is a followup of GHSA-wm47-8v5p-wjpj/CVE-2021-21295 which did
miss to fix this one case. This was fixed as part of 4.1.61.Final.

A flaw was found in the Java logging library Apache Log4j in version 1.x . This
allows a remote attacker to execute code on the server if the deployed
application is configured to use JMSAppender.
In 1.x you will find that there are two places where lookups are done - that is
JMSAppender.java:207 and JMSAppender.java:222 - if you set TopicBindingName or
TopicConnectionFactoryBindingName to something that JNDI can handle - for
example "ldap://host:port/a" JNDI will do exactly the same thing it does for
2.x - so 1.x is vulnerable, just attack vector is "safer" as it depends on
configuration rather than user input

A flaw was found in the Apache Tomcat, where the payload length in a WebSocket
