Vulnerability Assessment

Weakness	CWE CWE-89 OWASP Top 10:2025 A05:2025 - Injection ASVS 5.0 V1 - Encoding and Sanitization Parameterized queries, prepared statements MITRE ATT&CK 2 techniques across 2 tactics: Initial Access, Persistence The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. Sign in to read
Impact	The real-world risk is moderately high. The CVSS base score of 7.3 reflects critical weaknesses: network-accessible attack vector (AV:N), low attack complexity (AC:L), and no privileges required (PR:N), meaning any remote attacker can exploit this without authentication. The exploit maturity is rated as Proof-of-concept (E:P), and a working exploit is publicly available on GitHub (https://github.com/dsdsadawada/CVE1/issues/4), lowering the barrier to entry significantly. However, the confidentiality, integrity, and availability impacts are all rated Low (C:L/I:L/A:L), suggesting limited scope per exploitation attempt. The vulnerability is not listed in CISA KEV, indicating no confirmed active exploitation campaigns yet. For organizations running this specific enrollment system with public internet exposure, this represents an immediate priority due to the combination of unauthenticated access, public exploit availability, and database compromise potential. The automation potential is high given the straightforward SQL injection nature.
Exploit ScenarioDerived	An unauthenticated remote attacker crafts a malicious HTTP request to the vulnerable enrollment system's URL https://[target]/sms/grades/index.php?view=edit&id=1&deptid=[SQL_PAYLOAD], injecting SQL commands through the deptid parameter. Using the publicly available proof-of-concept from GitHub (https://github.com/dsdsadawada/CVE1/issues/4), the attacker can extract sensitive student enrollment data, modify grade records, or enumerate database structure. The attack requires no special tools beyond a web browser or curl, and the low complexity means automated scanning tools can easily identify and exploit vulnerable instances exposed to the internet.

This Month Plan within 30 days. Why: MEDIUM severity (CVSS 4.0-6.9).

AnalysisAIv1 – Mar 26, 2026

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.

Earlier versions of this analysis (1)

v1 Mar 26, 2026 - 05:15 CVSS 6.9

A SQL injection vulnerability exists in itsourcecode Online Enrollment System version 1.0 that allows remote attackers to manipulate database queries through the 'deptid' parameter in the /sms/grades/index.php file. The vulnerability requires no authentication or user interaction (CVSS:3.1 AV:N/AC:L/PR:N/UI:N) and can result in unauthorized data access, modification, and potential denial of service. A public proof-of-concept exploit is available on GitHub, significantly increasing the risk of active exploitation.

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.

Technical ContextAI · show details

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.

Executive ViewAI

Why It Matters

A critical SQL injection vulnerability in our Online Enrollment System (version 1.0) allows attackers to access, modify, or destroy student and enrollment data without authentication. With a public exploit available and no vendor patch currently released, immediate action is required to prevent data breach and operational disruption.

Business Impact: Severe

Compensating Controls

Implement WAF rules to filter SQL injection payloads in the 'deptid' parameter; restrict network access to the enrollment system through IP whitelisting or VPN requirement; disable the grades module if operationally feasible; apply database-level input validation and parameterized queries if source code access is available; enable database activity monitoring and alerting for unusual queries; implement rate limiting on the vulnerable endpoint.
