CVE-2023-20873

A flaw was found in Spring Boot. This targets specifically 'spring-boot-actuator-autoconfigure' package. This issue occurs when an application is deployed to Cloud Foundry, which could be susceptible to a security bypass.

Specifically, an application is vulnerable when all of the following are true:

     * You have code that can handle requests that match /cloudfoundryapplication/**. Typically, this will be if there is a catch-all request mapping which matches /**.
     * The application is deployed to Cloud Foundry.

An application is not vulnerable if any of the following is true:

      * The application is not deployed to Cloud Foundry
      * You have disabled Cloud Foundry actuator endpoints with management.cloudfoundry.enabled set to false.
      * Your application does not have handler mappings that can handle requests to /cloudfoundryapplication/**.

The following Red Hat products do not ship the affected software component and so are not affected:

     * Red Hat Enterprise Linux 8, 9
     * Enterprise Application Platform 6, 7, 8, XP
     * Data Grid 7, 8
     * Migration Toolkit for Runtimes

     * Red Hat AMQ Clients 2
     * Red Hat AMQ Streams 2
     * Red Hat Fuse 6
     * Red Hat Fuse 7
     * Red Hat VertX 4

The following Red Hat products ship the affected software but do not enable or do not ship the vulnerable classes, and so are affected but at Low security impact.

     * Red Hat Decision Manager 7
     * Red Hat Process Automation Manager 7
     * Red Hat Single Sign-On 7

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.
