CVE-2025-7819: Cross-Site Scripting Vulnerability in PHPGurukul Apartment Visitors Management System
This blog post details a recently discovered vulnerability, CVE-2025-7819, affecting the PHPGurukul Apartment Visitors Management System. We'll break down the vulnerability, its potential impact, and provide recommendations to secure your system.
Vulnerability Details
- CVE ID: CVE-2025-7819
- Description: A Cross-Site Scripting (XSS) vulnerability exists in PHPGurukul Apartment Visitors Management System 1.0. This allows an attacker to inject malicious scripts into the web application, potentially leading to data theft, session hijacking, or defacement of the website.
- CVSS Score and Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:N/I:L/A:N, Base Score: 2.4 (LOW). This means the vulnerability is remotely exploitable with low complexity, requires high privileges, and user interaction. Successful exploitation has a limited impact on data integrity.
- Exploit Requirements: An attacker needs to be authenticated with high privileges to inject the malicious script and requires a victim to interact with the injected script.
- Affected Vendor, Product, Version: PHPGurukul, Apartment Visitors Management System, 1.0
- CWE: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'). CWE-79 occurs when a web application does not properly sanitize user-supplied input before displaying it on a web page. This allows attackers to inject malicious scripts that are executed in the victim's browser.

Exploitability & Real-World Risk
While the CVSS score is low, the risk should not be dismissed. An attacker who has already compromised an administrator account could use this XSS vulnerability to target other administrators or users of the system. This could be used to phish for credentials or spread misinformation through the application. Given that apartment visitor management systems often handle sensitive personal data, even a low-severity vulnerability can have significant consequences if exploited in a targeted manner.
Recommendations
- Apply the Patch: Check PHPGurukul for any available patches or updates that address this vulnerability.
- Input Validation: Implement robust input validation and sanitization on all user-supplied data to prevent malicious scripts from being injected.
- Principle of Least Privilege: Ensure that users are granted only the minimum level of access required to perform their duties. This can limit the impact of a compromised account.
- Web Application Firewall (WAF): Consider implementing a WAF to detect and block malicious requests.
Technical Insight
The vulnerability exists in the /create-pass.php file, specifically due to insufficient sanitization of the visname argument in an HTTP POST request. This allows an attacker with high privileges to inject arbitrary JavaScript code, which will be executed in the browser of anyone who views the page containing the injected script. This is a classic example of a Stored XSS vulnerability.
