mbCONNECT24: Cleartext Storage of Sensitive Information
CVE-2024-23942 is a high-severity cleartext storage of sensitive information vulnerability in mbCONNECT24 from MB connect line, 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 2.16.2 as the first without the flaw, so updating mbCONNECT24 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.12% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update mbCONNECT24 to 2.16.2 or a later version.
- Update mbNET to 8.2.0 or a later version.
- Update mbNET.rokey to 8.2.0 or a later version.

Official description
A local user may find a configuration file on the client workstation with unencrypted sensitive data. This allows an attacker to impersonate the device or prevent the device from accessing the cloud portal which leads to a DoS.

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.
