CVE-2022-42467: 
Java vulnerability analysis and mitigation

CVE-2022-42467 is a security vulnerability in Apache Isis's H2 webconsole module that was disclosed on October 19, 2022. The vulnerability exists in the prototype mode where the H2 webconsole module, accessible from the Prototype menu, was automatically made available with direct database query capabilities. This posed a security risk as the console was accessible without explicit configuration (Openwall List).

The vulnerability is classified with CWE-1188. The issue stems from the H2 webconsole being automatically available in prototype mode without requiring explicit enablement or proper authentication mechanisms. The console provides direct database query capabilities, which could potentially expose sensitive database information if left unsecured (NVD).

The impact of this vulnerability is considered low as it only affects systems running in prototype mode, and the H2 webconsole is never available in production mode. However, if exploited in a prototype environment, it could potentially allow unauthorized access to database information through the webconsole (Openwall List).

As of Apache Isis version 2.0.0-M8, several security measures have been implemented. The webconsole requires explicit enablement through the 'isis.prototyping.h2-console.web-allow-remote-access' configuration property. Additionally, a new configuration parameter 'isis.prototyping.h2-console.generate-random-web-admin-password' (enabled by default) requires administrators to use a randomly generated password that is printed to the log as 'webAdminPass: xxx'. To revert to the original behavior, administrators need to set both 'isis.prototyping.h2-console.web-allow-remote-access=true' and 'isis.prototyping.h2-console.generate-random-web-admin-password=false' (Openwall List).
