Impact
- The NVD base score is 9.8 (critical), with high confidentiality, integrity and availability impact in the vector.
- VulDB also published lower scores in other CVSS versions, so the severity depends on which scoring source is used.

- No confirmed exploitation in the wild appears in the sources consulted.
- SSVC data in the record marks exploitation as proof of concept and automatable as yes.
Remediation and mitigation
- The record lists no fixed version and no vendor patch. Check the vendor site and the VulDB entry for updates.
- Restrict access to the affected application to trusted networks until a fix or an adequate mitigation is confirmed.
- Where the code can be changed, use parameterized queries and strict server-side validation of identifiers such as cos_id.
- If the application cannot be fixed, consider removing it from internet-facing use or isolating it.
Detection guidance
- Review web server and application logs for unusual or malformed values in requests to /edit_costumer.php.
- Watch for database error messages or abnormal response sizes on that endpoint.
- Check database accounts used by the application for unnecessary privileges.
Limitations of the available information
