CVE-2025-62673 TP-Link Systems Inc. CVE debrief

Who should care

Network administrators and security teams responsible for Archer AX53 and AX12 devices should assess exposure and apply necessary mitigations. They must verify exposure of Archer AX53 and AX12 devices in their network, assess network packet handling and tdpserver module configurations, and apply vendor-provided firmware updates. Additionally, they should monitor network activity for suspicious packet patterns and review compensating controls for exposed  

Why it matters

CVE-2025-62673 is a Heap-based Buffer Overflow vulnerability in Archer AX53 and AX12 devices that allows adjacent attackers to cause a segmentation fault or potentially execute arbitrary code. Defenders should prioritize verifying exposure, assessing network packet handling, and applying vendor-provided firmware updates.

• Verify exposure of Archer AX53 and AX12 devices
• Assess network packet handling and tdpserver module configurations
• Apply vendor-provided firmware updates
• Monitor network activity for suspicious packet patterns

Technical summary

The CVE record describes a Heap-based Buffer Overflow vulnerability in Archer AX53 v1.0 and AX12 v1.0 (tdpserver modules). Adjacent attackers can cause a segmentation fault or potentially execute arbitrary code via a specially crafted network packet.
