Описание
Improper Authentication vulnerability in Apache Tomcat meant that in some circumstances (e.g. CLIENT-CERT, SPNEGO) that a user would be authenticated even if the user did not exist in the DataSourceRealm.
This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.24, from 10.1.0-M1 through 10.1.57, from 9.0.0.M1 through 9.0.120.
The following versions were EOL at the time the CVE was created but are
known to be affected: from 8.5.0 through 8.5.100, from 7.0.0 through 7.0.109. Other unsupported versions may also be affected.
Users are recommended to upgrade to version 11.0.25, 10.1.58 or 9.0.121, which fix the issue.
A flaw was found in Apache Tomcat. This improper authentication vulnerability allows a remote attacker to be authenticated even if their user account does not exist in the DataSourceRealm, under specific circumstances such as CLIENT-CERT or SPNEGO authentication. This can lead to unauthorized access to the system.
Отчет
This Important vulnerability in Apache Tomcat allows unauthorized access when configured with CLIENT-CERT or SPNEGO authentication alongside a DataSourceRealm. This flaw could permit a user to be authenticated even if their account does not exist, bypassing intended security controls in Red Hat deployments where these specific configurations are in use.
Меры по смягчению последствий
To mitigate this issue, avoid using CLIENT-CERT or SPNEGO authentication methods with the DataSourceRealm in Apache Tomcat. Alternatively, restrict network access to the Apache Tomcat instance to trusted clients only, thereby limiting exposure to potential attackers. If changes are made to the Tomcat configuration, a service restart may be required for the changes to take effect.
