BIT-TOMCAT-2020-11996

A specially crafted sequence of HTTP/2 requests sent to Apache Tomcat 10.0.0 to 10.0.0, 9.0.0 to 9.0.35 and 8.5.0 to 8.5.55 could trigger high CPU usage for several seconds. If a sufficient number of such requests were made on concurrent HTTP/2 connections, the server could become unresponsive...

BIT-TOMCAT-2020-13934

An h2c direct connection to Apache Tomcat 10.0.0 to 10.0.0, 9.0.0 to 9.0.36 and 8.5.1 to 8.5.56 did not release the HTTP/1.1 processor after the upgrade to HTTP/2. If a sufficient number of such requests were made, an OutOfMemoryException could occur leading to a denial of service...

BIT-TOMCAT-2020-13935

The payload length in a WebSocket frame was not correctly validated in Apache Tomcat 9.0.0 through 9.0.36, 8.5.0 to 8.5.56 and 7.0.27 to 7.0.104. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service...

If an HTTP/2 client connecting to Apache Tomcat 9.0.0 through 9.0.37 or 8.5.0 to 8.5.57 exceeded the agreed maximum number of concurrent streams for a connection in violation of the HTTP/2 protocol, it was possible that a subsequent request made on that connection could contain HTTP headers -...

BIT-TOMCAT-2020-17527 Apache Tomcat: Request header mix-up between HTTP/2 streams

While investigating bug 64830 it was discovered that Apache Tomcat 9.0.0 through 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead ...

When using Apache Tomcat versions 9.0.0 through 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to 7.0.103 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...

BIT-TOMCAT-2021-24122 Apache Tomcat information disclosure

When serving resources from a network location using the NTFS file system, Apache Tomcat versions 9.0.0 through 9.0.39, 8.5.0 to 8.5.59 and 7.0.0 to 7.0.106 were susceptible to JSP source code disclosure in some configurations. The root cause was the unexpected behaviour of the JRE API...

BIT-TOMCAT-2021-25122 Apache Tomcat h2c request mix-up

When responding to new h2c connection requests, Apache Tomcat versions 9.0.0 through 9.0.41 and 8.5.0 to 8.5.61 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...
