A vulnerability has been found in PHPGurukul Online Library Management System 3.0 and classified as problematic. This vulnerability affects unknown code of the file /admin/student-history.php. The manipulation of the argument stdid leads to cross site scripting. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.
AnalysisAI
Reflected cross-site scripting in PHPGurukul Online Library Management System 3.0 allows a remote, low-privileged attacker to inject arbitrary JavaScript into the admin panel by manipulating the stdid parameter in /admin/student-history.php. A victim admin user who loads a crafted URL or page would execute attacker-controlled script in their browser session, enabling session hijacking or DOM manipulation. A public proof-of-concept exploit has been disclosed on GitHub; EPSS remains very low at 0.03% (8th percentile), consistent with a niche product with limited real-world attack surface.
Technical ContextAI
The vulnerability resides in the PHP-based admin interface of PHPGurukul's Online Library Management System version 3.0 (CPE: cpe:2.3:a:phpgurukul:online_library_management_system:3.0:*:*:*:*:*:*:*). The stdid parameter passed to /admin/student-history.php is reflected into the HTML response without adequate output encoding or input sanitization, satisfying the definition of CWE-79 (Improper Neutralization of Input During Web Page Generation). PHPGurukul produces open-source PHP/MySQL management systems primarily targeted at small educational institutions. The attack vector is network-accessible, requires low-privilege authentication (PR:L in the CVSS 4.0 vector), and passive user interaction (UI:P - a victim admin must load the crafted request in their browser).
RemediationAI
No vendor-released patch has been identified at time of analysis - the vulnerability was reported via VulDB (ID 316300) with a PoC on GitHub, but no patched version number appears in the available references. Administrators running this system should immediately apply output encoding to the stdid parameter in /admin/student-history.php, using PHP's htmlspecialchars() with ENT_QUOTES before reflecting user-supplied input into HTML responses. As a compensating control, restrict access to the /admin/ directory to trusted IP ranges via web server configuration (e.g., Apache Require ip or nginx allow/deny directives) - this does not eliminate the flaw but substantially limits the attacker's ability to deliver a crafted URL to an admin. Additionally, deploying a Web Application Firewall (WAF) rule to filter <script> and event-handler patterns in the stdid parameter provides shallow-defence coverage. Monitor VulDB entry 316300 and the phpgurukul.com site for an official patch release.
