Nodegrid OS: Cleartext Storage of Sensitive Information
CVE-2023-44037 is a high-severity cleartext storage of sensitive information vulnerability in Nodegrid OS from Zpesystems, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 5.8.14, 5.10.6 as the first without the flaw, so updating Nodegrid OS to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.48% 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 Nodegrid OS to 5.8.14 or 5.10.6, whichever matches your release line, or a later version.
- Read the advisory on psirt.zpesystems.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

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.
