CVE-2023-49134
📋 TL;DR
An unauthenticated remote command execution vulnerability in TP-Link wireless access points allows attackers to execute arbitrary commands by sending specially crafted network packets. This affects TP-Link EAP225 V3 and EAP115 V4 access points with specific vulnerable firmware versions. Attackers can gain complete control of affected devices without authentication.
💻 Affected Systems
- TP-Link AC1350 Wireless MU-MIMO Gigabit Access Point (EAP225 V3)
- TP-Link N300 Wireless Access Point (EAP115 V4)
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the access point allowing attackers to pivot to internal networks, intercept/modify traffic, install persistent backdoors, or use the device for further attacks.
Likely Case
Attackers gain remote shell access to execute commands, potentially installing malware, modifying configurations, or using the device as a foothold for lateral movement.
If Mitigated
With proper network segmentation and access controls, impact is limited to the access point itself without allowing network pivoting.
🎯 Exploit Status
Exploit requires sending a sequence of network packets to trigger the vulnerability. Technical details and proof-of-concept are publicly available in the Talos Intelligence report.

🔍 How to Verify
Check if Vulnerable:
Check firmware version in device web interface: EAP225 V3 v5.1.0 Build 20220926 or EAP115 V4 v5.0.4 Build 20220216Check Version:
Check via web interface or SSH if enabled: cat /etc/versionVerify Fix Applied:
Verify firmware version has been updated to a version newer than the vulnerable builds📡 Detection & Monitoring
Log Indicators:
- Unusual command execution in system logs
- Multiple failed authentication attempts followed by successful access
- Unexpected process creation
Network Indicators:
- Unusual network traffic to/from access point management interface
- Suspicious packets to port 29808 (uclited service)
