Original description
The description as published by the source.
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.
