Description

An improper input validation vulnerability in the configuration service for processing encrypted credential data has been identified in Tapo C200 v5.  An attacker can send oversized crypted ciphertext values that may trigger exception handling failures, due to insufficient validation, causing the affected device to crash or restart. Successful exploitation may temporarily disrupt HTTPS management and monitoring functionality, resulting in a denial-of-service (DoS) condition until the service recovers.

Affected configurations

• tp-link tapo c200 firmware (< 1.4.6)
