CVE-2025-7375: Omada EAP610 v3 DoS Vulnerability

CVE-2025-7375 Overview

A denial-of-service (DoS) vulnerability has been identified in the TP-Link Omada EAP610 v3 wireless access point. An attacker with adjacent network access can send specially crafted requests to the device's HTTP service, causing it to crash. This results in temporary service unavailability until the device is manually rebooted, potentially disrupting wireless network connectivity for all connected users.

Critical Impact

Adjacent network attackers can crash the HTTP service on Omada EAP610 v3 access points, causing network disruption until manual reboot is performed.

Affected Products

• TP-Link Omada EAP610 v3 firmware versions prior to 1.6.0
• Enterprise wireless access point deployments using vulnerable firmware
• Networks managed through Omada SDN controller with affected devices

Technical Details for CVE-2025-7375

Vulnerability Analysis

This vulnerability stems from improper input validation (CWE-20) in the HTTP service running on Omada EAP610 v3 access points. The firmware fails to properly validate incoming HTTP requests from adjacent network clients, allowing malformed or specially crafted requests to trigger a crash condition in the HTTP service.

The attack requires the attacker to be on the same network segment as the vulnerable access point, limiting remote exploitation scenarios. However, in enterprise environments where multiple users share the same network, this vulnerability could be exploited by any authenticated user on the local network or by an attacker who has gained initial access to the network perimeter.

When exploited successfully, the HTTP service becomes unresponsive and the device requires a manual reboot to restore full functionality. This creates an operational burden for network administrators and can lead to extended periods of service disruption if the attack is repeated.

Root Cause

The root cause of this vulnerability is improper input validation in the HTTP request handling code. The firmware does not adequately sanitize or validate the structure and content of incoming HTTP requests before processing them. When a malformed request is received, it triggers an unhandled exception or resource exhaustion condition that crashes the HTTP service.

This type of vulnerability often occurs when boundary conditions are not properly checked, when request parsing logic fails to handle unexpected input formats, or when memory allocation for request data is not properly bounded.

Attack Vector

The attack vector requires adjacent network access, meaning the attacker must be on the same local network segment as the target device. The attacker sends crafted HTTP requests to the access point's management interface, which triggers the crash condition. No authentication is required beyond network adjacency, and no user interaction is needed.

The attack can be performed repeatedly to maintain a persistent denial-of-service condition, effectively preventing network administrators from managing the device through its web interface and potentially disrupting wireless service for connected clients.

Detection Methods for CVE-2025-7375

Indicators of Compromise

• Unexpected reboots or service restarts of Omada EAP610 v3 access points
• HTTP service becoming unresponsive on the access point management interface
• Network logs showing repeated connection attempts to the access point's HTTP port from the same source
• User complaints about wireless connectivity loss correlating with access point unresponsiveness

Detection Strategies

• Monitor access point health status through Omada SDN controller for unexpected offline events
• Implement network-based intrusion detection to identify anomalous HTTP traffic patterns to access point management interfaces
• Configure SNMP or syslog monitoring to alert on device unavailability or service crashes
• Review network traffic logs for high volumes of HTTP requests directed at access point management ports

Monitoring Recommendations

• Enable logging on network infrastructure to capture traffic to and from access point management interfaces
• Configure alerts for access point offline events in the Omada controller dashboard
• Implement network segmentation monitoring to detect unauthorized access to management VLANs
• Regularly audit network access logs for suspicious patterns targeting embedded device HTTP services

How to Mitigate CVE-2025-7375

Immediate Actions Required

• Update Omada EAP610 v3 firmware to version 1.6.0 or later immediately
• Implement network segmentation to isolate access point management interfaces from general user traffic
• Restrict access to device management interfaces using firewall rules or VLAN configurations
• Monitor affected devices for signs of exploitation until patching is complete

Patch Information

TP-Link has released firmware version 1.6.0 which addresses this vulnerability. Administrators should download the updated firmware from the official Omada Networks Product Page and apply it to all affected devices. Additional technical details are available in the Omada Networks Document 118100.

For deployments managed through the Omada SDN controller, firmware updates can be deployed centrally to multiple access points simultaneously, reducing administrative overhead.

Workarounds

• Place access point management interfaces on a dedicated management VLAN with restricted access
• Implement access control lists (ACLs) to limit which hosts can communicate with the HTTP service on access points
• Consider disabling the local HTTP management interface if centralized management through Omada controller is sufficient
• Monitor for and block suspicious traffic patterns at network boundaries

# Example: Restrict access to management interface using iptables on upstream router
# Allow only management workstation subnet to access AP management ports
iptables -A FORWARD -d 192.168.1.0/24 -p tcp --dport 80 -s 10.10.10.0/24 -j ACCEPT
iptables -A FORWARD -d 192.168.1.0/24 -p tcp --dport 443 -s 10.10.10.0/24 -j ACCEPT
iptables -A FORWARD -d 192.168.1.0/24 -p tcp --dport 80 -j DROP
iptables -A FORWARD -d 192.168.1.0/24 -p tcp --dport 443 -j DROP
