CVE-2025-1496
📋 TL;DR
This vulnerability allows attackers to perform password brute-forcing attacks against BG-TEK Coslat Hotspot systems due to insufficient rate limiting on authentication attempts. Attackers can guess passwords through repeated login attempts, potentially gaining unauthorized access. All systems running Coslat Hotspot versions before 6.26.0.R.20250227 are affected.

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of hotspot system allowing attacker to gain administrative access, modify configurations, intercept user traffic, or deploy malware to connected devices.
Likely Case
Unauthorized access to hotspot management interface leading to configuration changes, service disruption, or credential theft from legitimate users.
If Mitigated
Failed login attempts logged but no successful compromise due to strong passwords and network segmentation.
🎯 Exploit Status
Exploitation requires no authentication and can be performed with basic brute-forcing tools. No special privileges needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.26.0.R.20250227
Vendor Advisory: https://www.coslat.com/tr/blog/28-02-2025-guncelleme
Restart Required: Yes
Instructions:
1. Backup current configuration. 2. Download version 6.26.0.R.20250227 from vendor portal. 3. Upload and apply firmware update through web interface. 4. Reboot system. 5. Verify version update.
🔧 Temporary Workarounds
Network-based rate limiting
allImplement network-level rate limiting using firewall or IPS to restrict authentication attempts
IP-based access control
allRestrict management interface access to trusted IP addresses only
🧯 If You Can't Patch
- Implement strong password policies (minimum 12 characters, complexity requirements)
- Deploy network segmentation to isolate hotspot management interface from untrusted networks
🔍 How to Verify
Check if Vulnerable:
Check current version in web interface under System > About. If version is earlier than 6.26.0.R.20250227, system is vulnerable.Check Version:
Not applicable - check via web interface or vendor-specific CLI commandsVerify Fix Applied:
Verify version shows 6.26.0.R.20250227 or later. Test authentication rate limiting by attempting multiple failed logins - should receive lockout or delay.📡 Detection & Monitoring
Log Indicators:
- Multiple failed authentication attempts from single IP
- Rapid succession of login attempts
- Authentication logs showing pattern of brute-forcing
Network Indicators:
- High volume of authentication requests to management port
- Traffic patterns showing systematic login attempts
