Description
This vulnerability, in the MAXHUB Pivot client application versions
prior to v1.36.2, may allow an attacker to obtain encrypted tenant email
addresses and related metadata from any tenant. Due to the presence of a
hardcoded AES key within the application, the encrypted data can be
decrypted, enabling access to tenant email addresses and associated
information in cleartext. Furthermore, an attacker may be able to cause a
denial-of-service condition by enrolling multiple unauthorized devices
into a tenant via MQTT, potentially disrupting tenant operations.
