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 from improper sanitization or validation of the 'adminname' parameter, which can be manipulated by an attacker to inject malicious scripts. This vulnerability is exploitable remotely without requiring prior authentication, although it does require some level of user interaction (e.g., an administrator visiting a crafted URL). The CVSS 4.0 base score is 5.1, indicating a medium severity level. The vector details highlight that the attack complexity is low, no privileges are required, but user interaction is necessary. The impact on confidentiality is none, integrity is low, and availability is none, suggesting the primary risk is the execution of arbitrary scripts in the context of an administrator's browser session. While no known exploits are currently in the wild, the public disclosure of the exploit code increases the risk of exploitation. The vulnerability could allow attackers to perform actions such as session hijacking, defacement of the admin interface, or phishing attacks targeting administrative users, potentially leading to further compromise of the system or sensitive data exposure indirectly through social engineering or session theft.

For European organizations using the PHPGurukul Time Table Generator System 1.0, this vulnerability poses a moderate risk primarily to administrative users. Successful exploitation could lead to unauthorized actions performed with admin privileges, potentially disrupting scheduling operations or exposing sensitive administrative data. Although the direct impact on confidentiality and availability is limited, the integrity of the system could be compromised, affecting trustworthiness of timetable data. In sectors such as education, public administration, or any organization relying on this system for critical scheduling, this could cause operational disruptions or reputational damage. Additionally, if attackers leverage stolen admin sessions or credentials obtained via XSS, they could escalate attacks to broader network resources. Given the remote exploitability and public availability of the exploit, European organizations should prioritize addressing this vulnerability to prevent targeted attacks, especially in environments where the timetable system interfaces with other critical infrastructure or sensitive personal data.

1. Immediate patching: Although no official patch links are provided, organizations should contact PHPGurukul for updates or apply community-provided patches that sanitize and validate the 'adminname' parameter properly. 2. Input validation and output encoding: Implement strict server-side input validation and context-aware output encoding for all user-supplied data, especially in admin interfaces. 3. Content Security Policy (CSP): Deploy a robust CSP to restrict the execution of unauthorized scripts and mitigate the impact of XSS attacks. 4. Admin interface access controls: Restrict access to the /admin/profile.php page using network-level controls such as VPNs or IP whitelisting to limit exposure. 5. User awareness and monitoring: Educate administrators about phishing risks and monitor logs for suspicious activities indicative of XSS exploitation attempts. 6. Web Application Firewall (WAF): Employ a WAF with rules to detect and block XSS payloads targeting the vulnerable parameter. 7. Regular security assessments: Conduct periodic code reviews and penetration testing focusing on input handling in administrative modules.
