Pavilion8®: Missing Encryption of Sensitive Data
CVE-2024-40620 is a high-severity missing encryption of sensitive data vulnerability in Pavilion8® from Rockwell Automation, 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. Affected Pavilion8® versions: 5.20. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.19% 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
- Check which version of Pavilion8® you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on rockwellautomation.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
CVE-2024-40620 IMPACT A vulnerability exists in the affected product due to lack of encryption of sensitive information. The vulnerability results in data being sent between the Console and the Dashboard without encryption, which can be seen in the logs of proxy servers, potentially impacting the data's confidentiality.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Missing Encryption of Sensitive Data
The product does not encrypt sensitive or critical information before storage or transmission.
How developers prevent this class of flaw
- Clearly specify which data or resources are valuable enough that they should be protected by encryption. Require that any transmission or storage of this data/resource should use well-vetted encryption algorithms.
- Compartmentalize the system to have safe areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
- When using industry-approved techniques, use them correctly. Don't cut corners by skipping resource-intensive steps (CWE-325). These steps are often essential for preventing common attacks.
