Exploitation Conditions

No special conditions - remote unauthenticated exploitation against default configurations of itsourcecode School Management System 1.0. The email parameter on the login form is injectable without any prior authentication, session, or token. The only prerequisite is network reachability to the web server hosting User_Login.php. Exploitation is limited by: network exposure (the server must be internet-facing or on a network the attacker can reach), and the extent of database impact depends on the MySQL user privileges granted to the PHP application - a least-privilege DB user reduces but does not eliminate risk.

Impact

The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms fully unauthenticated remote exploitation with no complexity barriers, and the E:P modifier documents that public exploit code exists. The impact ratings VC:L/VI:L/VA:L reflect bounded but real database access - the login query can be manipulated to bypass authentication or enumerate records, though full database takeover depends on DB user privileges. No KEV listing is present and EPSS data was not provided, but the pre-auth attack surface and available PoC combine to make this an accessible target for automated scanners; even a mid-sized municipal IT team in swidnica running this software on an internet-facing server should treat this as urgent due to the zero-friction exploitation path. The primary limiting factor is the deployment footprint: itsourcecode projects are predominantly used in academic and hobbyist environments rather than large enterprise settings, which reduces aggregate blast radius but does not diminish per-instance severity.

Exploit ScenarioDerived

An unauthenticated attacker sends an HTTP POST request to User_Login.php with a SQL injection payload in the email field (for example, a classic OR-true bypass such as ' OR '1'='1), causing the backend query to return a valid session or dump credential records. The public PoC on GitHub documents the exact payload and request format, enabling script-kiddie-level exploitation with no specialized knowledge.

AnalysisAIv1 – Sep 07, 2026

SQL injection in itsourcecode School Management System 1.0 allows unauthenticated remote attackers to manipulate the email parameter in User_Login.php, injecting arbitrary SQL into backend database queries at the pre-authentication login endpoint. With a public exploit available on GitHub, exploitation requires minimal skill and no credentials. The CVSS 4.0 vector confirms network-accessible, no-privilege exploitation with partial confidentiality, integrity, and availability impact against the underlying database.

RemediationAI

No vendor-released patch has been identified at time of analysis. The primary fix is to rewrite the email parameter handling in User_Login.php to use PHP PDO or MySQLi prepared statements with parameterized queries, which eliminates the injection surface entirely. As an immediate compensating control, deploy a web application firewall rule targeting SQL injection patterns on the login endpoint. If the application does not require internet exposure, restrict access to trusted IP ranges at the network perimeter. Disabling the email login field entirely (if an alternative auth path exists) removes the vulnerable parameter. Each workaround carries trade-offs: WAF rules can be bypassed with encoding; IP restriction limits legitimate access. Manual patching of the open-source PHP code is the only confirmed durable fix.

Technical ContextAI · show details

The vulnerability is a classic CWE-89 (SQL Injection) flaw in a PHP-based school administration application distributed freely by itsourcecode.com. The login file User_Login.php constructs database queries using unsanitized user-supplied input from the email POST parameter, without using prepared statements or parameterized queries. The CPE cpe:2.3:a:itsourcecode:school_management_system:*:*:*:*:*:*:*:* uses a wildcard version, indicating the flaw is present across all tracked releases. itsourcecode projects are PHP/MySQL stacks commonly deployed on shared hosting or LAMP servers by educational institutions and students as ready-made solutions.
