Package : tomcat9
CVE ID : CVE-2022-42252 CVE-2022-45143 CVE-2023-28708
Debian Bug : 1033475

Several security vulnerabilities have been discovered in the Tomcat
servlet and JSP engine.

CVE-2022-42252

Apache Tomcat was configured to ignore invalid HTTP headers via setting
rejectIllegalHeader to false. Tomcat did not reject a request containing an
invalid Content-Length header making a request smuggling attack possible if
Tomcat was located behind a reverse proxy that also failed to reject the
request with the invalid header.

CVE-2022-45143

The JsonErrorReportValve in Apache Tomcat did not escape the type, message
or description values. In some circumstances these are constructed from
user provided data and it was therefore possible for users to supply values
that invalidated or manipulated the JSON output.

CVE-2023-28708

When using the RemoteIpFilter with requests received from a reverse proxy
via HTTP that include the X-Forwarded-Proto header set to https, session
cookies created by Apache Tomcat did not include the secure attribute. This
could result in the user agent transmitting the session cookie over an
insecure channel.


For the stable distribution (bullseye), these problems have been fixed in version 9.0.43-2~deb11u6.

We recommend that you upgrade your tomcat9 packages.
