Integer Overflow in Tapo C200 V3 HTTPS Server Causes DoS

Publication date: 2025-12-20

Last updated on: 2025-12-20

Assigner: TPLink

Description
The HTTPS server on Tapo C200 V3 does not properly validate the Content-Length header, which can lead to an integer overflow. An unauthenticated attacker on the same local network segment can send crafted HTTPS requests to trigger excessive memory allocation, causing the device to crash and resulting in denial-of-service (DoS).

Executive Summary

This vulnerability exists in the HTTPS server of the Tapo C200 V3 device, where it does not properly validate the Content-Length header in HTTPS requests. This improper validation can cause an integer overflow when processing specially crafted requests. An unauthenticated attacker on the same local network can exploit this by sending malicious HTTPS requests, which triggers excessive memory allocation and causes the device to crash, resulting in a denial-of-service (DoS). [2]

Impact Analysis

If exploited, this vulnerability can cause the Tapo C200 V3 device to crash due to excessive memory allocation triggered by crafted HTTPS requests. This results in a denial-of-service (DoS), making the device unavailable and potentially disrupting any services or security monitoring it provides. [2]

Mitigation Strategies

Users are strongly advised to update their Tapo C200 V3 devices to firmware version Tapo C200(US)_V3_1.4.5 Build 251104 or later via the Tapo Mobile Application to mitigate this vulnerability. [2]
