Critical severity: a successful attack would have severe impact.

What to do

  1. Check which version of Telpo Mdm you run against the affected versions below, and install the vendor's latest release.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Telpo MDM 1.4.6 thru 1.4.9 for Android contains sensitive administrator credentials and MQTT server connection details (IP/port) that are stored in plaintext within log files on the device's external storage. This allows attackers with access to these logs to: 1. Authenticate to the MDM web platform to execute administrative operations (device shutdown/factory reset/software installation); 2. Connect to the MQTT server to intercept/publish device data.

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.
