Package : tomcat9
Version : 9.0.31-1~deb10u9
CVE ID : CVE-2023-24998 CVE-2023-41080 CVE-2023-42795 CVE-2023-44487
CVE-2023-45648
Several security vulnerabilities have been discovered in the Tomcat
servlet and JSP engine.
CVE-2023-24998
Denial of service. Tomcat uses a packaged renamed copy of Apache Commons
FileUpload to provide the file upload functionality defined in the Jakarta
Servlet specification. Apache Tomcat was, therefore, also vulnerable to the
Commons FileUpload vulnerability CVE-2023-24998 as there was no limit to
the number of request parts processed. This resulted in the possibility of
an attacker triggering a DoS with a malicious upload or series of uploads.
CVE-2023-41080
Open redirect. If the ROOT (default) web application is configured to use
FORM authentication then it is possible that a specially crafted URL could
be used to trigger a redirect to an URL of the attackers choice.
CVE-2023-42795
Information Disclosure. When recycling various internal objects, including
the request and the response, prior to re-use by the next request/response,
an error could cause Tomcat to skip some parts of the recycling process
leading to information leaking from the current request/response to the
next.
CVE-2023-44487
DoS caused by HTTP/2 frame overhead (Rapid Reset Attack)
CVE-2023-45648
Request smuggling. Tomcat did not correctly parse HTTP trailer headers. A
specially crafted, invalid trailer header could cause Tomcat to treat a
single request as multiple requests leading to the possibility of request
smuggling when behind a reverse proxy.
For Debian 10 buster, these problems have been fixed in version
9.0.31-1~deb10u9.
We recommend that you upgrade your tomcat9 packages.
