Exploitability
| CWE ID | Description |
|---|---|
| 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. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |

AI Powered Q&A
Can you explain this vulnerability to me?
[{'type': 'paragraph', 'content': "CVE-2026-4324 is a vulnerability in the Katello plugin for Red Hat Satellite, specifically in the rubygem-katello component. It is caused by improper sanitization of user input in the 'sort_by' parameter of the '/api/hosts/bootc_images' API endpoint."}, {'type': 'paragraph', 'content': 'An attacker can exploit this flaw by injecting arbitrary SQL commands into the ORDER BY clause of the database query. Although some complex queries are blocked by the underlying framework, the attacker can still manipulate the query to cause database errors or perform Boolean-based Blind SQL injection.'}] [1]
How can this vulnerability impact me? :
This vulnerability can lead to a Denial of Service (DoS) by triggering database errors, which may disrupt the normal operation of the affected system.
Additionally, it may enable Boolean-based Blind SQL injection, potentially allowing an attacker to extract sensitive information from the database.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
I don't know
How can this vulnerability be detected on my network or system? Can you suggest some commands?
[{'type': 'paragraph', 'content': 'This vulnerability involves SQL injection via the sort_by parameter in the /api/hosts/bootc_images API endpoint of the Katello plugin for Red Hat Satellite. Detection can focus on monitoring or testing this API endpoint for unusual or malformed input that triggers database errors.'}, {'type': 'paragraph', 'content': 'One approach is to send crafted requests to the /api/hosts/bootc_images endpoint with various SQL injection payloads in the sort_by parameter and observe if database errors or abnormal responses occur.'}, {'type': 'paragraph', 'content': 'Example command using curl to test for SQL injection behavior:'}, {'type': 'list_item', 'content': "curl -k -u <username>:<password> -X GET 'https://<satellite-server>/api/hosts/bootc_images?sort_by=id;--'"}, {'type': 'list_item', 'content': "curl -k -u <username>:<password> -X GET 'https://<satellite-server>/api/hosts/bootc_images?sort_by=id OR 1=1--'"}, {'type': 'paragraph', 'content': 'If these requests cause database errors or unusual responses, it may indicate the presence of the vulnerability.'}] [1]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting access to the vulnerable API endpoint to trusted users only, as exploitation requires authentication.
Additionally, monitor and audit API usage for suspicious requests targeting the sort_by parameter.
Applying any available patches or updates from Red Hat for the Katello plugin or the rubygem-katello component is critical to fully resolve the issue.
