Incomplete Cleanup

org.apache.tomcat:tomcat is an implementation of the Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket technologies.

Affected versions of this package are vulnerable to Incomplete Cleanup when recycling various internal objects. An error could cause some parts of the recycling process to be skipped, leading to information leaking from the current request/response to the next. An attacker can gain unauthorised access to sensitive information by exploiting this error.

How to fix Incomplete Cleanup?

Upgrade org.apache.tomcat:tomcat to version 8.5.94, 9.0.81, 10.1.14, 11.0.0-M12 or higher.

[8.5.0,8.5.94) [9.0.0-M1,9.0.81) [10.1.0-M1,10.1.14) [11.0.0-M1,11.0.0-M12)

Improper Input Validation

org.apache.tomcat:tomcat is an implementation of the Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket technologies.

Affected versions of this package are vulnerable to Improper Input Validation due to the improper handling of HTTP trailer headers. An attacker can manipulate the server into treating a single request as multiple requests by sending a specially crafted, invalid trailer header. This could lead to request smuggling when the server is behind a reverse proxy.

How to fix Improper Input Validation?

Upgrade org.apache.tomcat:tomcat to version 8.5.94, 9.0.81, 10.1.14, 11.0.0-M12 or higher.

[8.5.0,8.5.94) [9.0.0-M1,9.0.81) [10.1.0-M1,10.1.14) [11.0.0-M1,11.0.0-M12)

Access Restriction Bypass

org.apache.tomcat:tomcat is an implementation of the Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket technologies.

Affected versions of this package are vulnerable to Access Restriction Bypass. 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.

The vulnerability is limited to the ROOT (default) web application.

How to fix Access Restriction Bypass?

Upgrade org.apache.tomcat:tomcat to version 8.5.93, 9.0.80, 10.1.13, 11.0.0-M11 or higher.

[8.5.0,8.5.93) [9.0.0-M1,9.0.80) [10.1.0-M1,10.1.13) [11.0.0-M1,11.0.0-M11)

Cross-site Scripting (XSS)

org.apache.tomcat:tomcat is an implementation of the Java Servlet, JavaServer Pages, Java Expression Language and Java WebSocket technologies.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS). The Form authentication example in the examples web application displayed user provided data without filtering, exposing a potential XSS vulnerability.

Note: This is a vulnerability in webapps/examples/jsp/security/protected/index.jsp file which is not used in any of the core Tomcat artifacts, and which therefore only affects users who did not remove the examples of web application as documented in the Tomcat security guide.

How to fix Cross-site Scripting (XSS)?

Upgrade org.apache.tomcat:tomcat to version 8.5.82, 9.0.65, 10.0.23, 10.1.0-M17 or higher.

[8.5.50,8.5.82) [9.0.30,9.0.65) [10.0.0-M1,10.0.23) [10.1.0-M1,10.1.0-M17)
