MXview One Series: Cleartext Storage of Sensitive Information

CVE-2024-6785 is a high-severity cleartext storage of sensitive information vulnerability in MXview One Series from Moxa, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 1.3.0 as the first without the flaw, so updating MXview One Series to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.11% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

The configuration file stores credentials in cleartext. An attacker with local access rights can read or modify the configuration file, potentially resulting in the service being abused due to sensitive information exposure.

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.
