Official description
The /device/signin end-point for the Ourphoto App version 1.4.1 discloses clear-text password information for functionality within the picture frame devices. The deviceVideoCallPassword and mqttPassword are returned in clear-text. The lack of sessions management and presence of insecure direct object references allows to return password information for other end-users devices. Many of the picture frame devices offer video calling, and it is likely this information can be used to abuse that functionality.

The underlying weakness: Cleartext Storage of Sensitive Information
The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.
How developers prevent this class of flaw
- When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to encrypt the data at rest.
- In some systems/environments such as cloud, the use of double encryption (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
