This manipulation of the argument oid causes sql injection. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks.
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 · high confidenceSQL injection vulnerability in PHPGurukul Online Shopping Portal 2.1 allows remote attackers to inject malicious SQL queries via the 'oid' parameter in /cancelorder.php. The application fails to properly sanitize user input before using it in database queries.

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 PHPGurukul Online Shopping Portal installationSearch for files or directories related to the PHPGurukul Online Shopping Portal application on your web server. Common locations include /var/www/html, /www, or C:\inetpub\wwwroot.Affected if The application is present on the server
-
Determine the installed versionLook for a version file, README, or admin panel that displays the application version. Check the source code for version strings or configuration files.Affected if The installed version matches 2.1 or falls within the affected version range
-
Verify the vulnerable file existsCheck if /cancelorder.php exists in the web application's directory structure on the server.Affected if The file /cancelorder.php is present and web-accessible
-
Confirm the vulnerable parameter handlingReview the source code of cancelorder.php and examine how the oid parameter is processed and incorporated into SQL queries.Affected if The oid parameter is directly concatenated into SQL queries without sanitization or prepared statements
-
Review web server access logsAnalyze web server access logs for requests to /cancelorder.php containing the oid parameter, especially those with SQL syntax characters like quotes, UNION, or semicolons.Affected if Suspicious requests with SQL injection payloads targeting the oid parameter are found in logs
A user is affected if the PHPGurukul Online Shopping Portal version 2.1 is installed and the web-accessible /cancelorder.php file handles the oid parameter without parameterized queries.

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 dataReplace dynamic SQL queries with parameterized queries or prepared statements for the oid parameter in /cancelorder.php, and implement input validation.
