Summary

Initialization of a resource with an insecure default vulnerability in OpenText Advanced Authentication Server allows Excessive Allocation.

This issue affects Advanced Authentication Server: from 6.4.0.0 through 6.4.3.x, from 6.5.0.0 through 6.5.0.x, and from 6.6.0.0 through 6.6.1.0.

The fix for this is issue is to create a secure configuration.  The 6.6.2.0 release has a best practice entry if the configuration is unsecure.

A secure configuration is to NOT allow creation/recreation of Unauthenticated Endpoints.  If creation/recreation of Unauthenticated Endpoints is required, you should only allow it from trusted networks.

To remedy this issue, change your configuration to NOT allow creation/recreation of Unauthenticated Endpoints. If you require Unauthenticated Endpoints, you MUST change your configuration to use a non-empty whitelist to specify the trusted networks.  An empty whitelist will allow all networks to create/recreate endpoints.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
