Improper Input Validation vulnerability in Apache Tomcat.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.21, from 10.1.0-M1 through 10.1.54, from 9.0.0.M1 through 9.0.117, from 10.0.0-M1 through 10.0.27.
Older, end of support versions may also be affected.
Users are recommended to upgrade to version [FIXED_VERSION], which fixes the issue.
Apache Tomcat did not validate HTTP/2 request headers, triggering unexpected application behavior, as applications may presume that header values exposed through the Servlet API would be valid.
Отчет
This vulnerability is rated Moderate severity for Red Hat products because triggering the issue requires HTTP/2 protocol support to be explicitly enabled on the Tomcat connector, which is not the standard default. Although malformed incoming header data may reach downstream servlets without expected validation checks, the flaw does not directly compromise the host system or grant remote code execution. The overall blast radius is limited to unexpected behavior in specific web applications that rely entirely on the servlet container for request header sanitation.
