Performing a manipulation of the argument ID results in sql injection. Remote exploitation of the attack is possible. The exploit has been made public and could be used.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA SQL injection vulnerability exists in the itsourcecode Online Doctor Appointment System 1.0 within the /admin/doctor_action.php file. The 'ID' parameter is not properly sanitized before being used in SQL queries, allowing remote attackers to inject arbitrary SQL commands. This is a critical pre-authentication SQL injection in an admin-facing script.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if the Online Doctor Appointment System is installedLocate the web application directory. Common paths include /var/www/html/, /www/html/, or C:\inetpub\wwwroot\. Look for the /admin/doctor_action.php file.Affected if The /admin/doctor_action.php file exists in the web root
-
Confirm the exact versionCheck for version indicators such as a version.php file, readme.txt, or admin dashboard footer which often displays the software version. Compare against version 1.0.Affected if The installed version is exactly 1.0
-
Verify the vulnerable endpoint is accessibleCheck if the /admin/ directory is web-accessible. Attempt to access the doctor_action.php file via HTTP/HTTPS request to confirm it responds.Affected if The /admin/doctor_action.php endpoint is reachable from the web
-
Check if the ID parameter is acceptedSend a test request to /admin/doctor_action.php with an ID parameter (e.g., ?ID=1) and observe if the application processes it without error handling.Affected if The ID parameter is processed by the script without proper sanitization being evident in error responses
If the Online Doctor Appointment System version 1.0 is installed with the /admin/doctor_action.php file accessible and processing the ID parameter, the environment is affected by this SQL injection vulnerability.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement prepared statements/parameterized queries for all database operations, particularly those using the ID parameter. Validate and sanitize all user inputs before using them in SQL queries. If a patch is available from the vendor, apply it immediately.
