CVE-2025-7925 Overview

CVE-2025-7925 is a reflected cross-site scripting (XSS) vulnerability [CWE-79] in PHPGurukul Online Banquet Booking System version 1.0. The flaw resides in the /admin/login.php endpoint, where the user_login and userpassword parameters are rendered without adequate output encoding. Remote attackers can craft malicious URLs that execute arbitrary JavaScript in the victim's browser session. The exploit details have been publicly disclosed, increasing the likelihood of opportunistic abuse against exposed instances.

Critical Impact

Successful exploitation allows attackers to execute arbitrary JavaScript in an administrator's browser context, enabling session theft, credential harvesting, and administrative interface manipulation through a single crafted link.

Affected Products

  • PHPGurukul Online Banquet Booking System 1.0
  • Affected file: /admin/login.php
  • Affected parameters: user_login, userpassword

Technical Details for CVE-2025-7925

Vulnerability Analysis

The vulnerability is a reflected cross-site scripting issue in the administrative login handler of PHPGurukul Online Banquet Booking System 1.0. When the login page processes the user_login or userpassword request parameters, the application echoes attacker-supplied input back into the HTML response without proper sanitization or context-aware encoding. An attacker can craft a URL containing JavaScript payloads and lure an authenticated administrator, or any target visiting the admin login page, into triggering execution.

Because the vulnerable endpoint is the administrative login form, the browser context of the victim is trusted for administrative operations. Injected scripts can read cookies not marked HttpOnly, exfiltrate CSRF tokens, submit authenticated requests, and manipulate the DOM to phish valid credentials from legitimate users. The exploit requires user interaction but no authentication or elevated privileges.

Root Cause

The root cause is improper neutralization of input during web page generation [CWE-79]. The /admin/login.php script includes user-controlled parameter values in the HTML response, most likely within form field value attributes or inline error messaging, without HTML entity encoding. PHP applications commonly reintroduce this class of defect when developers omit htmlspecialchars() or equivalent encoding for reflected form state.

Attack Vector

Exploitation is remote and requires only that a victim click or load a crafted URL. The attacker constructs a request to /admin/login.php with a malicious payload embedded in user_login or userpassword. When the server reflects the payload into the response, the browser parses it as executable script. Delivery vectors include phishing emails, malicious advertisements, or links posted on channels the target administrator is likely to visit. The vulnerability mechanism is described in the VulDB advisory and public GitHub report.

Detection Methods for CVE-2025-7925

Indicators of Compromise

  • HTTP requests to /admin/login.php containing script tags, event handlers (onerror=, onload=), or URL-encoded JavaScript in the user_login or userpassword parameters.
  • Web server access logs showing unusually long query strings or unusual character sequences (<, >, %3C, %3E) targeting the admin login endpoint.
  • Outbound requests from administrator workstations to attacker-controlled domains immediately after visiting the banquet booking admin portal.

Detection Strategies

  • Deploy web application firewall (WAF) rules that inspect POST and GET parameters submitted to /admin/login.php for XSS signatures.
  • Enable verbose HTTP access logging on the web server and alert on requests containing reflected script payloads.
  • Correlate browser telemetry from administrator endpoints with web application traffic to identify script execution originating from the admin login page.

Monitoring Recommendations

  • Monitor authentication logs for administrator sessions initiated from unexpected geolocations or IP addresses following a reported phishing event.
  • Track Content Security Policy (CSP) violation reports if CSP is deployed in front of the application.
  • Review referrer headers on admin portal traffic to identify inbound links from external phishing infrastructure.

How to Mitigate CVE-2025-7925

Immediate Actions Required

  • Restrict network access to /admin/login.php using IP allowlists or VPN-gated access until a patched release is available.
  • Instruct administrators to avoid clicking untrusted links that reference the banquet booking admin interface.
  • Deploy a WAF signature that blocks reflected XSS payloads targeting the user_login and userpassword parameters.

Patch Information

No vendor patch has been published for PHPGurukul Online Banquet Booking System 1.0 at the time of writing. Organizations should monitor the PHPGurukul website for updated releases and consider replacing the application if the vendor does not remediate the issue.

Workarounds

  • Add server-side input filtering that HTML-encodes all reflected values using htmlspecialchars($input, ENT_QUOTES, 'UTF-8') before echoing to the response.
  • Enforce a strict Content Security Policy that disallows inline scripts (script-src 'self') to limit the impact of reflected payloads.
  • Set the HttpOnly and Secure flags on session cookies to reduce the value of stolen cookies via XSS.
bash
# Example nginx configuration to add CSP and cookie flags
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'" always;
add_header X-XSS-Protection "1; mode=block" always;
add_header X-Content-Type-Options "nosniff" always;

# PHP session hardening (php.ini)
# session.cookie_httponly = 1
# session.cookie_secure = 1
# session.cookie_samesite = "Strict"
