| CVE | Weakness | CVSS v3 | Details |
|---|---|---|---|
| CVE-2024-2425 | CWE-120 Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') | 7.5 High |
A denial-of-service vulnerability exists in the PowerFlex 527 due to improper input validation in the device. If exploited, the web server will crash and need a manual restart to recover it. Mitigation: Rockwell Automation does not currently have a fix for these vulnerabilities. Users of the affected software are encouraged to apply risk mitigations and security best practices, where possible. Mitigation: Implement network segmentation confirming the device is on an isolated network. Mitigation: Disable the web server, if not needed. The web server is disabled by default. Disabling this feature is available in v2.001.x and later. Affected, fixed & timelineAffected:
