Apache Tomcat - Authentication Bypass

Critical severity GitHub Reviewed Published Nov 18, 2024 to the GitHub Advisory Database • Updated Nov 18, 2024

Package

maven org.apache.tomcat:tomcat-catalina (Maven)

Affected versions

< 9.0.96
>= 10.1.0-M1, < 10.1.30
>= 11.0.0-M1, <= 11.0.0-M26

Patched versions

9.0.96
10.1.30
11.0.1

Description

Unchecked Error Condition vulnerability in Apache Tomcat. If Tomcat is configured to use a custom Jakarta Authentication (formerly JASPIC) ServerAuthContext component which may throw an exception during the authentication process without explicitly setting an HTTP status to indicate failure, the authentication may not fail, allowing the user to bypass the authentication process. There are no known Jakarta Authentication components that behave in this way.

This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.0-M26, from 10.1.0-M1 through 10.1.30, from 9.0.0-M1 through 9.0.95.

Users are recommended to upgrade to version 11.0.0, 10.1.31 or 9.0.96, which fix the issue.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
