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

Successful
exploitation may temporarily disrupt HTTPS management and monitoring
functionality, resulting in a denial-of-service (DoS) condition until the
service recovers.
