Improper Input Validation

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Improper Input Validation due to the improper parsing of HTTP trailer headers. An attacker can manipulate the server into treating a single request as multiple requests by sending a trailer header that exceeds the header size limit. 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-catalina to version 8.5.96, 9.0.83, 10.1.16, 11.0.0-M10 or higher.

[8.5.0,8.5.96) [9.0.0-M1,9.0.83) [10.1.0-M1,10.1.16) [11.0.0-M1,11.0.0-M10)

Incomplete Cleanup

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

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-catalina to version 8.5.94, 9.0.81, 10.1.14, 11.0.0-M12 or higher.

Access Restriction Bypass

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

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-catalina 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)

Unprotected Transport of Credentials

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Unprotected Transport of Credentials when using the RemoteIpFilter with requests received from a reverse proxy via HTTP, in which the X-Forwarded-Proto header is set to https. Session cookies do not include the secure attribute, so the user agent may transmit the session cookie over an insecure channel.

How to fix Unprotected Transport of Credentials?

Upgrade org.apache.tomcat:tomcat-catalina to version 8.5.86, 9.0.72, 10.1.6, 11.0.0-M3 or higher.

[8.5.0,8.5.86) [9.0.0-M1,9.0.72) [10.1.0-M1,10.1.6) [11.0.0-M1,11.0.0-M3)

Denial of Service (DoS)

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Denial of Service (DoS) when an attacker sends a large number of request parts in a series of uploads or a single multipart upload.

NOTE: After upgrading to the fixed version, the setFileCountMax() must be explicitly set to avoid this vulnerability.

How to fix Denial of Service (DoS)?

Upgrade org.apache.tomcat:tomcat-catalina to version 8.5.85, 9.0.71, 10.1.5, 11.0.0-M3 or higher.

[8.5.0,8.5.85) [9.0.0-M1,9.0.71) [10.1.0-M1,10.1.5) [11.0.0-M1,11.0.0-M3)

Improper Input Validation

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Improper Input Validation such that the JsonErrorReportValve does not escape the type, message or description values. In some circumstances these are constructed from user provided data and it is possible for users to supply values that invalidate or manipulate the JSON output.

How to fix Improper Input Validation?

Upgrade org.apache.tomcat:tomcat-catalina to version 8.5.84, 9.0.69, 10.1.2 or higher.

Information Exposure

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Information Exposure. due to a concurrency bug that could cause client connections to share an Http11Processor instance resulting in responses, or part responses, to be received by the wrong client.

How to fix Information Exposure?

Upgrade org.apache.tomcat:tomcat-catalina to version 8.5.78, 9.0.62, 10.0.20, 10.1.0-M14 or higher.

[8.5.0,8.5.78) [9.0.0-M1,9.0.62) [10.0.0-M1,10.0.20) [10.1.0-M1,10.1.0-M14)

Insufficient Technical Documentation

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Insufficient Technical Documentation. The documentation for the EncryptInterceptor incorrectly stated it enabled Tomcat clustering to run over an untrusted network. This was not correct. While the EncryptInterceptor does provide confidentiality and integrity protection, it does not protect against all risks associated with running over any untrusted network, particularly DoS risks.

Note: The documentation was updated in version 9.0.63.

How to fix Insufficient Technical Documentation?

Upgrade org.apache.tomcat:tomcat-catalina to version 9.0.63 or higher.

Privilege Escalation

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Privilege Escalation via a time of check, time of use vulnerability that allows a local attacker to perform actions with the privileges of the user that the Tomcat process is using. This issue is only exploitable when Tomcat is configured to persist sessions using the FileStore.

How to fix Privilege Escalation?

Upgrade org.apache.tomcat:tomcat-catalina to version 8.5.74, 9.0.57, 10.0.15, 10.1.0-M9 or higher.

[8.5.55,8.5.74) [9.0.0,9.0.57) [10.0.0-M1,10.0.15) [10.1.0-M1,10.1.0-M9)

Improper Input Validation

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Improper Input Validation. Queries made by the JNDI Realm did not always correctly escape parameters. Parameter values could be sourced from user provided data (e.g., user names) as well as configuration data provided by an administrator. In limited circumstances it was possible for users to authenticate using variations of their user name and/or to bypass some of the protection provided by the LockOut Realm.

How to fix Improper Input Validation?

Upgrade org.apache.tomcat:tomcat-catalina to version 10.0.6, 9.0.46, 8.5.66, 7.0.109 or higher.

[10.0.0-M1,10.0.6) [9.0.0.M1,9.0.46) [8.5.0,8.5.66) [7.0.0,7.0.109)

Remote Code Execution (RCE)

org.apache.tomcat:tomcat-catalina is a Tomcat Servlet Engine Core Classes and Standard implementations.

Affected versions of this package are vulnerable to Remote Code Execution (RCE). The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue.

How to fix Remote Code Execution (RCE)?

Upgrade org.apache.tomcat:tomcat-catalina to version 10.0.2, 9.0.43, 8.5.63, 7.0.108 or higher.

[10.0.0-M1,10.0.2) [9.0.0.M1,9.0.43) [8.5.0,8.5.63) [7.0.0,7.0.108)
