Attack Chain

1. The attacker identifies an instance of Simple Online Food Ordering System 1.0 accessible over the network.
2. The attacker targets the /admin/ajax.php endpoint.
3. The attacker crafts a malicious HTTP POST request where the 'action' parameter is set to 'login'.
4. The attacker injects SQL payloads into the 'Username' parameter field within the request body.
5. The application backend fails to sanitize the input before processing it in a database query.
6. The injected SQL is executed by the database, allowing the attacker to manipulate queries or extract data.
7. The final objective is reached, such as unauthorized authentication bypass or database exfiltration.

Impact

Successful exploitation of CVE-2026-76048 allows for unauthorized interaction with the application database. This could result in the disclosure of sensitive administrative credentials, customer information, or food order records, as well as the potential for full application compromise. The impact is significant for organizations relying on this software for managing online food service operations, as the vulnerability is remotely exploitable without authentication.

Recommendation

Prioritized actions for security teams:

• Deploy the Sigma rule below to detect inbound exploitation attempts targeting the identified administrative login endpoint.
• Review web server access logs for requests to '/admin/ajax.php' containing SQL metacharacters (e.g., ', --, UNION, SELECT) within the 'Username' field.
• Apply security patches or implement an upstream WAF rule to block requests containing SQL injection patterns directed at this specific application component until a patch can be applied.
