CVE-2019-0221

The SSI printenv command in Apache Tomcat 9.0.0.M1 to 9.0.0.17, 8.5.0 to 8.5.39 and 7.0.0 to 7.0.93 echoes user provided data without escaping and is, therefore, vulnerable to XSS. SSI is disabled by default. The printenv command is intended for debugging and is unlikely to be present in a production website.

Updated tomcat packages fix security vulnerabilities:

The HTTP/2 implementation accepted streams with excessive numbers of SETTINGS frames and also permitted clients to keep streams open without reading/writing request/response data. By keeping streams open for requests that utilised the Servlet API's blocking I/O, clients were able to cause server-side threads to block eventually leading to thread exhaustion and a DoS (CVE-2019-0199).

The SSI printenv command echoes user provided data without escaping and is, therefore, vulnerable to XSS. SSI is disabled by default. The printenv command is intended for debugging and is unlikely to be present in a production website (CVE-2019-0221).

The fix for CVE-2019-0199 was incomplete and did not address HTTP/2 connection window exhaustion on write. By not sending WINDOW_UPDATE messages for the connection window (stream 0) clients were able to cause server-side threads to block eventually leading to thread exhaustion and a DoS (CVE-2019-10072).

The tomcat package has been updated to version 9.0.21 to fix these issues. The tomcat-native package has also been updated to version 1.2.23.

This update for tomcat to version 9.0.20 fixes the following issues:

This update for tomcat6 fixes the following issues:

CVE-2020-9484 (bsc#1171928) Apache Tomcat Remote Code Execution via session persistence

If an attacker was able to control the contents and name of a file on a server configured to use the PersistenceManager, then the attacker could have triggered a remote code execution via deserialization of the file under their control.

CVE-2019-12418 (bsc#1159723) Local privilege escalation by manipulating the RMI registry and performing a man-in-the-middle attack

When Tomcat is configured with the JMX Remote Lifecycle Listener, a local attacker without access to the Tomcat process or configuration files was able to manipulate the RMI registry to perform a man-in-the-middle attack to capture user names and passwords used to access the JMX interface. The attacker could then use these credentials to access the JMX interface and gain complete control over the Tomcat instance.

CVE-2019-0221 (bsc#1136085) The SSI printenv command echoed user provided data without escaping, which made it vulnerable to XSS.
