CVE-2025-52352
📋 TL;DR
The Aikaan IoT management platform v3.25.0325-5-g2e9c59796 has a critical authentication bypass vulnerability where the sign-up API endpoint remains accessible even when the UI sign-up option is disabled. This allows unauthenticated attackers to create accounts and gain unauthorized access to admin portals. All deployments using this vulnerable version are affected.

⚠️ Risk & Real-World Impact
Worst Case
Attackers create admin-level accounts, take full control of IoT management platform, compromise connected IoT devices, and potentially pivot to internal networks.
Likely Case
Unauthorized users register accounts, access sensitive IoT management functions, and potentially disrupt IoT operations.
If Mitigated
With proper network segmentation and monitoring, impact limited to isolated IoT management segment with quick detection of unauthorized account creation.
🎯 Exploit Status
Simple HTTP POST request to sign-up API endpoint with minimal technical skill required.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: https://www.aikaan.io
Restart Required: No
Instructions:
No official patch available. Contact vendor for updated version or apply workarounds.
🔧 Temporary Workarounds
API Endpoint Blocking
linuxBlock access to sign-up API endpoint at network/firewall level
iptables -A INPUT -p tcp --dport [Aikaan-port] -m string --string "POST /api/signup" --algo bm -j DROP
Web Server Configuration
allConfigure web server to deny access to sign-up endpoint
Location /api/signup { deny all; } (nginx)
<location path="/api/signup"><system.webServer><security><requestFiltering><verbs applyToWebDAV="true"><add verb="POST" allowed="false"/></verbs></requestFiltering></security></system.webServer></location> (IIS)
🧯 If You Can't Patch
- Implement network segmentation to isolate Aikaan platform from internet and restrict access to authorized IPs only
- Enable detailed logging for all API authentication attempts and monitor for unauthorized sign-up requests
🔍 How to Verify
Check if Vulnerable:
Send POST request to /api/signup endpoint with valid user data. If account creation succeeds while UI sign-up is disabled, system is vulnerable.Check Version:
Check Aikaan platform version in admin interface or configuration filesVerify Fix Applied:
Attempt same POST request after applying workarounds - should receive 403/404 error or connection refused.📡 Detection & Monitoring
Log Indicators:
- Successful POST requests to /api/signup endpoint
- New user account creation from unauthorized IPs
- Multiple failed login attempts from newly created accounts
Network Indicators:
- HTTP POST requests to /api/signup endpoint
- Unusual traffic patterns to authentication endpoints
