DescriptionCVE.org

A security vulnerability has been detected in itsourcecode Online Enrollment System 1.0. This vulnerability affects unknown code of the file /sms/grades/index.php?view=edit&id=1 of the component Parameter Handler. The manipulation of the argument deptid leads to sql injection. The attack is possible to be carried out remotely. The exploit has been disclosed publicly and may be used. VulDB is the best source for vulnerability data and more expert information about this specific topic.

AnalysisAI

SQL injection in itsourcecode Online Enrollment System 1.0 allows unauthenticated remote attackers to execute arbitrary SQL commands via the deptid parameter in the grades index page. Public exploit code is available for this vulnerability, and no patch is currently available. The attack requires only network access with no additional complexity or user interaction.

Technical ContextAI

This vulnerability affects the itsourcecode Online Enrollment System version 1.0 (CPE: cpe:2.3:a:itsourcecode:online_enrollment_system:*:*:*:*:*:*:*:*), specifically in the parameter handling mechanism of the grades management interface. The issue is classified as CWE-89 (SQL Injection), meaning the application fails to properly sanitize user-supplied input in the 'deptid' parameter before incorporating it into SQL queries. The vulnerability exists in a PHP-based web application within the /sms/grades/index.php endpoint when processing the 'view=edit' operation, allowing attackers to inject arbitrary SQL commands that are executed by the backend database. This classic input validation failure enables manipulation of SQL query structure through specially crafted parameter values.

RemediationAI

Organizations should immediately discontinue use of itsourcecode Online Enrollment System version 1.0 in production environments, as no patch availability is indicated in the vulnerability data (CVSS RL:X indicates remediation level is unavailable or not defined). Contact the vendor via https://itsourcecode.com/ to inquire about security updates or patched versions. As interim mitigations until a patch is available, implement input validation and parameterized queries at the application layer if source code modification is possible, deploy a web application firewall (WAF) with SQL injection detection rules to filter malicious requests to /sms/grades/index.php, restrict network access to the enrollment system to trusted IP ranges only, and monitor database query logs for suspicious patterns. Consider replacing this system with a more actively maintained alternative given the apparent lack of vendor security response indicated by the remediation level status.
