critical Tenable Self-Hosted Container Security Plugin ID 410866

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In Alerta before version 8.1.0, users may be able to bypass LDAP authentication if they provide an empty
 password when Alerta server is configure to use LDAP as the authorization provider. Only deployments where
 LDAP servers are configured to allow unauthenticated authentication mechanism for anonymous authorization
 are affected. A fix has been implemented in version 8.1.0 that returns HTTP 401 Unauthorized response for
 any authentication attempts where the password field is empty. As a workaround LDAP administrators can
 disallow unauthenticated bind requests by clients. (CVE-2020-26214)
