CVE-2025-7941 is a cross-site scripting (XSS) vulnerability identified in version 1.0 of the PHPGurukul Time Table Generator System, specifically within an unspecified function in the /admin/profile.php file. The vulnerability arises due to improper sanitization or validation of the 'adminname' parameter, which can be manipulated by an attacker to inject malicious scripts. This flaw allows remote attackers to execute arbitrary JavaScript code in the context of the affected web application without requiring authentication, although user interaction is necessary to trigger the payload. The vulnerability is classified as 'problematic' with a CVSS 4.0 base score of 5.1 (medium severity), reflecting moderate impact and ease of exploitation. The attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:L), and user interaction needed (UI:P). The vulnerability impacts confidentiality and integrity to a limited extent (VC:N, VI:L), without affecting availability. No patches or official fixes have been disclosed at the time of publication, and while no known exploits are currently observed in the wild, public disclosure of the exploit code increases the risk of exploitation. The vulnerability primarily affects administrative interfaces, potentially allowing attackers to hijack admin sessions, steal cookies, or perform actions on behalf of administrators if successful. Given that the Time Table Generator System is a web-based application used for scheduling and administrative purposes, exploitation could lead to unauthorized access or manipulation of scheduling data, impacting organizational operations.

For European organizations using PHPGurukul Time Table Generator System 1.0, this XSS vulnerability poses a moderate risk. Successful exploitation could lead to session hijacking of administrative users, unauthorized data manipulation, or phishing attacks targeting administrators. This could disrupt internal scheduling processes, leading to operational inefficiencies or data integrity issues. While the vulnerability does not directly compromise system availability or cause data breaches at scale, the administrative nature of the affected interface means that attackers could gain footholds for further attacks or lateral movement within the network. Organizations in sectors such as education, public administration, or any entities relying on this software for timetable management could face reputational damage and operational disruptions. The remote exploitability and public availability of the exploit code increase the urgency for mitigation, especially in environments where administrative users access the system from less secure networks.

To mitigate CVE-2025-7941, European organizations should immediately implement input validation and output encoding on the 'adminname' parameter within /admin/profile.php to neutralize malicious scripts. Since no official patch is available, organizations should consider the following practical steps: 1) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting the 'adminname' parameter. 2) Restrict access to the administrative interface by IP whitelisting or VPN-only access to reduce exposure. 3) Enforce strict Content Security Policy (CSP) headers to limit the execution of unauthorized scripts. 4) Conduct regular security awareness training for administrators to recognize phishing or suspicious activity. 5) Monitor logs for unusual requests or error patterns related to the admin profile page. 6) If feasible, upgrade or replace the affected software with a more secure alternative or a patched version once available. 7) Implement multi-factor authentication (MFA) for administrative accounts to reduce the risk of session hijacking consequences.
