CVE-2025-28202
📋 TL;DR
This vulnerability allows attackers to enable SSH and Telnet services on Victure RX1800 routers without authentication. Attackers can gain administrative access to the router, potentially compromising the entire network. All users of Victure RX1800 EN_V1.0.0_r12_110933 are affected.
💻 Affected Systems
- Victure RX1800
📦 What is this software?
Rx1800 Firmware by Govicture
⚠️ Risk & Real-World Impact
Worst Case
Complete network compromise - attackers gain full router control, intercept all traffic, deploy malware to connected devices, and pivot to internal systems.
Likely Case
Router takeover leading to DNS hijacking, credential theft, and network surveillance of all connected devices.
If Mitigated
Limited to router configuration changes if network segmentation isolates the router from critical systems.
🎯 Exploit Status
The vulnerability requires no authentication and has a public proof-of-concept available, making exploitation trivial.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: Yes
Instructions:
1. Check Victure website for firmware updates. 2. Download latest firmware. 3. Access router admin panel. 4. Navigate to firmware update section. 5. Upload and apply new firmware. 6. Reboot router.
🔧 Temporary Workarounds
Disable remote management
allDisable SSH and Telnet services and ensure router admin interface is not accessible from WAN
Network segmentation
allIsolate router management interface to dedicated VLAN with strict access controls
🧯 If You Can't Patch
- Replace affected router with a different model that receives security updates
- Implement strict firewall rules blocking all inbound access to router management ports (22, 23, 80, 443)
🔍 How to Verify
Check if Vulnerable:
Check router firmware version in admin panel. If version is EN_V1.0.0_r12_110933, you are vulnerable.Check Version:
Login to router admin panel and check System Information or Firmware Version sectionVerify Fix Applied:
Verify firmware version has changed from vulnerable version and test that SSH/Telnet cannot be enabled without authentication.📡 Detection & Monitoring
Log Indicators:
- Unexpected SSH/Telnet service activation
- Failed authentication attempts to router admin
- Configuration changes without authorized user
Network Indicators:
- Unexpected SSH/Telnet traffic to router
- Port scans targeting router management ports
- Anomalous outbound connections from router
