CVE-2024-47477
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedDell PowerFlex Manager, versions prior to 4.5.1.1, contain an improper certificate validation vulnerability. A remote unauthenticated attacker could potentially exploit this vulnerability leading to man-in-the-middle attack in tandem with DNS cache poisoning.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceDell PowerFlex Manager versions prior to 4.5.1.1 contain an improper certificate validation vulnerability that allows a remote unauthenticated attacker to potentially conduct man-in-the-middle attacks, especially when combined with DNS cache poisoning. The vulnerability stems from inadequate validation of SSL/TLS certificates during secure communications.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm Dell PowerFlex Manager is installedLocate the PowerFlex Manager installation by checking for the product service or management interface, typically accessible via the product's web UI or command-line interface if installed on the systemAffected if PowerFlex Manager is not present on the system
-
Identify the installed PowerFlex Manager versionAccess the product's web interface, about page, or use the appropriate command-line tool provided by Dell to query the installed version numberAffected if The version returned is less than 4.5.1.1 (for example, 4.5.0.0, 4.0.x, or any version prior to 4.5.1.1)
-
Verify SSL/TLS secure communications are enabledCheck the PowerFlex Manager configuration settings for SSL/TLS certificate usage, typically found in the security or communication settings of the management interfaceAffected if Secure communications with SSL/TLS certificate validation are configured and active
The environment is affected if Dell PowerFlex Manager is installed with a version prior to 4.5.1.1 and SSL/TLS secure communications are enabled, as this combination allows the improper certificate validation vulnerability to be exploitable.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped4.5.1.1
Upgrade Dell PowerFlex Manager to version 4.5.1.1 or later to obtain the fixed certificate validation logic.
PowerFlex Manager 4.5.1.1
- 1. Back up the current PowerFlex Manager configuration and data according to Dell backup procedures
