Summary

A heap-based buffer overflow vulnerability was identified in multiple TP-Link Tapo cameras in the HTTP POST body parsing logic due to missing validation of remaining buffer capacity after dynamic allocation, due to insufficient boundary validation when handling externally supplied HTTP input. An attacker on the same network segment could trigger heap memory corruption conditions by sending crafted payloads that cause write operations beyond allocated buffer boundaries. Successful exploitation causes a Denial-of-Service (DoS) condition, causing the device's process to crash or become unresponsive.

Risk Assessment

An attacker on the same network can remotely crash or hang the cameras, disrupting monitoring and device availability.

Recommendation

Update the TP-Link Tapo camera firmware to the latest version containing the fix.
