CVE-2025-41025
📋 TL;DR
A stored cross-site scripting (XSS) vulnerability in Poultry Farm Management System v1.0 allows attackers to inject malicious scripts via the 'category' and 'product' parameters in the /farm/sell_product.php endpoint. This affects all users of the vulnerable system, potentially compromising their sessions and data. The vulnerability exists due to insufficient input validation in POST requests.
💻 Affected Systems
- Poultry Farm Management System
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal administrator credentials, hijack user sessions, deface the application, or redirect users to malicious sites, potentially leading to complete system compromise.
Likely Case
Attackers inject malicious scripts that steal session cookies or credentials from authenticated users, enabling unauthorized access to the farm management system.
If Mitigated
With proper input validation and output encoding, the malicious scripts would be neutralized, preventing any client-side execution.
🎯 Exploit Status
Exploitation requires sending crafted POST requests to the vulnerable endpoint, but specific exploit details are not publicly documented.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-poultry-farm-management-system
Restart Required: No
Instructions:
1. Review the vendor advisory for updates. 2. Implement input validation and output encoding for the 'category' and 'product' parameters. 3. Sanitize all user inputs before processing.
🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side validation to reject or sanitize malicious input in the 'category' and 'product' parameters.
Not applicable - requires code modification
Web Application Firewall (WAF)
allDeploy a WAF with XSS protection rules to block malicious payloads targeting the vulnerable endpoint.
Not applicable - configuration dependent
🧯 If You Can't Patch
- Restrict access to the /farm/sell_product.php endpoint to trusted users only using network controls.
- Implement Content Security Policy (CSP) headers to mitigate script execution from untrusted sources.
🔍 How to Verify
Check if Vulnerable:
Test by submitting a simple XSS payload (e.g., <script>alert('test')</script>) in the 'category' or 'product' parameters via POST to /farm/sell_product.php and check if it executes when the page is viewed.Check Version:
Check the application's version information in its interface or configuration files, as specific commands are not provided by the vendor.Verify Fix Applied:
After implementing fixes, repeat the test with XSS payloads to ensure they are properly sanitized or blocked and do not execute in the browser.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to /farm/sell_product.php with script tags or encoded payloads in parameters
- Multiple failed validation attempts on the sell_product endpoint
Network Indicators:
- HTTP POST traffic to /farm/sell_product.php containing suspicious strings like <script>, javascript:, or encoded characters
SIEM Query:
source="web_server" AND url="/farm/sell_product.php" AND (method="POST") AND (request_body CONTAINS "<script>" OR request_body CONTAINS "javascript:")
