Detailsinfo

A vulnerability classified as critical was found in Red Hat Satellite 6 on Red. This vulnerability affects an unknown code block of the file /api/hosts/bootc_images of the component Katello Plugin. The manipulation of the argument sort_by with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at access.redhat.com. This vulnerability was named CVE-2026-4324 since 03/17/2026. The exploitation appears to be easy. The attack can be initiated remotely. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $5k-$25k at the moment (estimation calculated on 06/06/2026). This vulnerability is assigned to T1505 by the MITRE ATT&CK project.
