PowerFlex Manager (Appliance): Incorrect Default Permissions
CVE-2025-32749 is a high-severity incorrect default permissions vulnerability in PowerFlex Manager (Appliance) from Dell, 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 IC 48.378.00, IC 48.383.00 as the first without the flaw, so updating PowerFlex Manager (Appliance) to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.13% 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 PowerFlex Manager (Appliance) to IC 48.378.00 or IC 48.383.00, whichever matches your release line, or a later version.
- Update PowerFlex Manager (Rack) to 3.7.8.0 or 3.8.3.0, whichever matches your release line, or a later version.
- Update Powerflex Appliance Intelligent Catalog to 48.383.00 or a later version.

The underlying weakness: Incorrect Default Permissions
During installation, installed file permissions are set to allow anyone to modify those files.
How developers prevent this class of flaw
- The architecture needs to access and modification attributes for files to only those users who actually require those actions.
- 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.
