CVE-2025-44885
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on affected FW-WGS-804HPT devices by exploiting a stack overflow in the SNMPv3 configuration interface. Attackers can achieve complete system compromise without authentication. Organizations using this specific device model and version are affected.
💻 Affected Systems
- FW-WGS-804HPT
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise leading to device takeover, data exfiltration, and use as pivot point into internal networks.
Likely Case
Remote code execution allowing attacker to install malware, modify device configuration, or disrupt network services.
If Mitigated
Limited impact if device is isolated behind firewalls with strict network segmentation and access controls.
🎯 Exploit Status
Public technical details available in reference link. Stack overflow vulnerabilities in embedded devices are commonly weaponized.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Unknown
Vendor Advisory: Unknown
Restart Required: No
Instructions:
1. Contact vendor for patch availability. 2. If patch exists, download from vendor portal. 3. Upload firmware via web interface. 4. Reboot device after update.
🔧 Temporary Workarounds
Disable SNMPv3 Remote Engine ID Configuration
allRemove or restrict access to the vulnerable SNMPv3 configuration function
Network Segmentation
allIsolate affected devices from untrusted networks
🧯 If You Can't Patch
- Immediately isolate device from internet and restrict access to management interface
- Implement strict firewall rules allowing only necessary traffic to/from the device
🔍 How to Verify
Check if Vulnerable:
Check device firmware version via web interface or CLI. If version is v1.305b241111, device is vulnerable.Check Version:
Check via web interface: System > Firmware Information, or via CLI if availableVerify Fix Applied:
Verify firmware version has been updated to a version later than v1.305b241111.📡 Detection & Monitoring
Log Indicators:
- Unusual POST requests to web_snmpv3_remote_engineId_add_post endpoint
- Large payloads in remote_ip parameter
- Device crash/restart logs
Network Indicators:
- Exploit traffic patterns to management interface
- Unusual outbound connections from device after compromise
