Lifecycle Timeline
4DescriptionCVE.org
A flaw has been found in itsourcecode University Management System 1.0. Impacted is an unknown function of the file /admin_single_student_update.php. This manipulation of the argument st_name causes cross site scripting. The attack may be initiated remotely. The exploit has been published and may be used.
AnalysisAI
A stored cross-site scripting (XSS) vulnerability exists in itsourcecode University Management System version 1.0 within the /admin_single_student_update.php file, where the st_name parameter fails to properly sanitize user input. An authenticated administrator with high privileges can inject malicious scripts that execute in the context of other users' browsers, potentially leading to session hijacking, credential theft, or unauthorized administrative actions. A proof-of-concept exploit has been publicly disclosed on GitHub, increasing real-world exploitation risk despite the low CVSS score of 2.4.
Technical ContextAI
The vulnerability is a CWE-79 (Improper Neutralization of Input During Web Page Generation) cross-site scripting flaw in a PHP-based web application. The flaw occurs in the student record update functionality where the st_name parameter is reflected or stored without proper HTML encoding or input validation before being rendered in the HTML response. This is a classic reflected or stored XSS vulnerability common in legacy PHP applications that predate modern security frameworks and automated output encoding. The attack vector is network-based with low complexity (AV:N/AC:L), meaning an attacker can exploit this remotely through standard HTTP requests, but requires high privilege level (PR:H) to access the administrative interface where the vulnerable parameter is processed.
RemediationAI
Immediately contact itsourcecode to determine patch availability for University Management System 1.0; if no patch is available, evaluate migration to an actively maintained alternative. As interim mitigation, restrict access to the /admin_single_student_update.php endpoint to a whitelist of trusted administrative IP addresses using firewall or reverse proxy rules, and implement a Web Application Firewall (WAF) with XSS detection rules to filter malicious payloads in the st_name parameter. Additionally, enforce Content Security Policy (CSP) headers with strict script-src directives to prevent inline script execution, and ensure all administrator accounts use strong, unique credentials with multi-factor authentication to reduce the risk of account compromise. Monitor administrative activity logs for suspicious parameter values or session anomalies.
