Description
A flaw was found in the Katello plugin for Red Hat Satellite. This vulnerability, caused by improper sanitization of user-provided input, allows a remote attacker to inject arbitrary SQL commands into the sort_by parameter of the /api/hosts/bootc_images API endpoint. This can lead to a Denial of Service (DoS) by triggering database errors, and potentially enable Boolean-based Blind SQL injection, which could allow an attacker to extract sensitive information from the database.
