Lifecycle Timeline
4Description
A vulnerability was found in PHPGurukul Student Result Management System 2.0. It has been classified as critical. Affected is an unknown function of the file /notice-details.php of the component GET Parameter Handler. The manipulation of the argument nid leads to sql injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used.
Analysis
CVE-2025-7534 is a critical SQL injection vulnerability in PHPGurukul Student Result Management System 2.0, exploitable through the 'nid' GET parameter in /notice-details.php. An unauthenticated remote attacker can manipulate this parameter to execute arbitrary SQL queries, potentially compromising confidentiality, integrity, and availability of the application database. Public exploit disclosure and confirmed attack surface (unauthenticated, network-accessible endpoint) elevate real-world risk despite the moderate CVSS 7.3 score.
Technical Context
The vulnerability resides in improper input validation and parameterization within the GET Parameter Handler of /notice-details.php. The underlying weakness is CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component, 'Injection'), specifically manifesting as SQL injection (CWE-89 subclass). PHPGurukul Student Result Management System 2.0 fails to sanitize or use prepared statements for the 'nid' parameter before incorporating it into SQL queries. This is a common vulnerability in legacy PHP applications that concatenate user input directly into SQL strings rather than using parameterized queries or ORM frameworks. The affected component processes GET parameters without adequate input validation, allowing attackers to break out of intended SQL syntax and inject malicious SQL commands.
Affected Products
Product: PHPGurukul Student Result Management System; Affected Version: 2.0; Vulnerable Component: /notice-details.php (GET Parameter Handler, specifically 'nid' parameter); Attack Vector: Remote, Unauthenticated. CPE would be formatted as: cpe:2.3:a:phpgurukul:student_result_management_system:2.0:*:*:*:*:*:*:* (exact CPE not provided in source data; vendor and product names inferred from description). No patch version information, vendor advisory link, or alternative product versions provided in source intelligence.
Remediation
Immediate actions: (1) Apply input validation to the 'nid' parameter—whitelist expected format (e.g., numeric ID only) and reject malformed input; (2) Refactor /notice-details.php to use parameterized queries (prepared statements) with placeholders instead of string concatenation; Example: Use mysqli_prepare() with ? placeholders or PDO with named parameters; (3) Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in GET parameters (e.g., UNION, SELECT, OR 1=1 signatures) as interim mitigation; (4) Apply the principle of least privilege to database user credentials used by the application (read-only for SELECT queries if feasible). Long-term: Upgrade to a patched version when released by PHPGurukul (vendor patch details not provided in source data—contact vendor directly or monitor security advisories at phpgurukul.com or GitHub repository). No vendor advisory link provided in source intelligence.
