CVE-2025-7818: Reflected Cross-Site Scripting (XSS) Vulnerability in PHPGurukul Apartment Visitors Management System

TL;DR: A reflected Cross-Site Scripting (XSS) vulnerability (CVE-2025-7818) has been identified in PHPGurukul Apartment Visitors Management System 1.0. This vulnerability allows an attacker to inject malicious scripts into the application via the 'categoryname' parameter in the /category.php file. Successful exploitation could lead to information theft or malicious actions on behalf of the user.

Vulnerability Details

  • CVE ID: CVE-2025-7818
  • Description: A reflected Cross-Site Scripting (XSS) vulnerability exists within the PHPGurukul Apartment Visitors Management System 1.0. The vulnerability occurs due to improper sanitization of the 'categoryname' parameter in the /category.php file.
  • CVSS Score:
    • CVSS v3.1: 3.5 (LOW) CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:N/I:L/A:N
    • Explanation: This CVSS score indicates a low severity vulnerability. It is network-based (AV:N), requires low privileges (PR:L) and user interaction (UI:R) to exploit. The impact is limited to potential integrity compromise (I:L), meaning the attacker can modify data, but confidentiality and availability are not affected.
  • Exploit Requirements: An attacker needs to craft a malicious URL containing the XSS payload and trick a logged-in user into clicking it.
  • 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')
    • Explanation: CWE-79 refers to scenarios where a web application does not properly sanitize user-supplied input before displaying it in a web page. This allows an attacker to inject malicious scripts that are executed in the victim's browser, potentially leading to account compromise, data theft, or defacement.

Exploitability & Real-World Risk

The exploitability of this vulnerability is considered moderate. An attacker needs to lure a logged-in user into clicking a specially crafted link. In a real-world scenario, this could be achieved through phishing emails or malicious advertisements. The impact of successful exploitation is limited to the scope of the user's permissions within the application. An attacker might be able to modify data that the user has access to, potentially affecting the application's functionality or defacing its appearance. However, the attacker cannot directly access sensitive data or disrupt the application's availability.

Recommendations

  • Apply Input Validation and Output Encoding: Implement robust input validation to sanitize user-supplied input before it's processed by the application. Use output encoding techniques to neutralize any potentially malicious characters before displaying data in web pages.
  • Implement a Content Security Policy (CSP): A CSP can help mitigate the risk of XSS attacks by restricting the sources from which the browser is allowed to load resources.
  • Educate Users: Train users to be cautious about clicking on suspicious links and entering sensitive information on untrusted websites.
  • Upgrade to a Patched Version: If available, upgrade to a patched version of the PHPGurukul Apartment Visitors Management System that addresses this vulnerability. Contact the vendor for updates.

Technical Insight

The vulnerability lies in the lack of proper input sanitization for the 'categoryname' parameter. When a user submits a request with a malicious script in this parameter, the application fails to neutralize it before displaying it in the web page. As a result, the browser executes the injected script, potentially giving the attacker control over the user's session or allowing them to perform actions on behalf of the user.
