Dell PowerFlex appliance: Improper Link Resolution Before File Access
CVE-2024-37143 is a critical-severity improper link resolution before file access vulnerability in Dell PowerFlex appliance from Dell, with a CVSS 3.1 base score of 9.8 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 46.381.00, 46.376.00 as the first without the flaw, so updating Dell PowerFlex appliance to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.76% chance of exploitation within 30 days, higher than 56% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Dell PowerFlex appliance to 46.381.00 or 46.376.00, whichever matches your release line, or a later version.
- Update Dell PowerFlex rack to 3.8.1.0 or 3.7.6.0, whichever matches your release line, or a later version.
- Update Dell PowerFlex custom node to 4.6.1.0 or a later version.
- Read the advisory on dell.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.

The underlying weakness: Improper Link Resolution Before File Access
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
How developers prevent this class of flaw
- Follow the principle of least privilege when assigning access rights to entities in a software system. Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
