Description

TP-Link Tapo C500 v2.0 contains an out-of-bounds function-pointer dispatch in its TDP (TP-Link Device Protocol) daemon. A single unauthenticated UDP datagram can cause an invalid indirect call, crashing the main service and resulting in a denial-of-service condition. Successful exploitation may allow an unauthenticated attacker with network access to the affected UDP service to repeatedly crash the TDP daemon, disrupting normal device operation and availability. No authentication, session establishment, or pairing is required to trigger the condition.

Attack-Flow Graph

Executive Summary

TP-Link Tapo C500 v2.0 has a flaw in its TDP daemon where an out-of-bounds function-pointer dispatch can be triggered by a single unauthenticated UDP datagram. This causes an invalid indirect call, crashing the main service and leading to a denial-of-service condition.

Detection Guidance

This vulnerability can be detected by monitoring for crashes in the TDP daemon on TP-Link Tapo C500 v2.0 devices. Check for repeated service disruptions or UDP datagram-related crashes. Use network scanning tools to identify affected devices by their CPE: TP-Link Systems Inc. Tapo C500 v2.0.

Impact Analysis

An attacker on the same network can send a malicious UDP packet to crash the TDP daemon, disrupting the device's normal operation. This results in loss of availability and requires no authentication or prior access.

Compliance Impact

This vulnerability causes a denial-of-service condition by crashing the TDP daemon, disrupting device availability. While not directly related to data handling, such disruptions could impact systems subject to GDPR or HIPAA by impairing access to critical services or data processing functions.

Mitigation Strategies

Immediately isolate affected TP-Link Tapo C500 v2.0 devices from the network to prevent exploitation. Disable the UDP service if possible or restrict network access to the device until a firmware update is applied.
