CVE-2024-45764
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 Enterprise SONiC OS, version(s) 4.1.x, 4.2.x, contain(s) a Missing Critical Step in Authentication vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to Protection mechanism bypass. This is a critical severity vulnerability so Dell recommends customers to upgrade at the earliest opportunity.
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 Enterprise SONiC OS versions 4.1.x and 4.2.x contain a Missing Critical Step in Authentication vulnerability that allows unauthenticated remote attackers to bypass protection mechanisms. This is an authentication bypass flaw in the network operating system's security controls.

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 Enterprise SONiC OS is runningAccess the device CLI and run 'show version' or check the login banner to verify the operating system is Dell Enterprise SONiC Distribution, not community SONiCAffected if The system is running Dell Enterprise SONiC OS (community SONiC is not affected)
-
Identify the installed SONiC OS versionRun 'show version' and note the SONiC version number displayed (typically in format like 4.1.x or 4.2.x)Affected if Version is 4.1.0 through 4.1.5, or 4.2.0 through 4.2.1 (falls within affected ranges)
-
Verify the specific version string formatCheck the full version output from 'show version' - Dell Enterprise versions will show as 'sonic_dell_e..._4.1.x' or similar Dell-specific build identifiersAffected if The version string indicates a Dell Enterprise build within 4.1.0-4.1.5 or 4.2.0-4.2.1 range
User is affected if the system runs Dell Enterprise SONiC OS version 4.1.0-4.1.5 or 4.2.0-4.2.1, where the authentication bypass vulnerability can be exploited by remote unauthenticated attackers.

Dell recommends upgrading to the latest available SONiC OS version at the earliest opportunity. Organizations should obtain the specific fixed version from Dell support and schedule a maintenance window for the upgrade.
Upgrade to Enterprise SONiC 4.1.6 or 4.2.2 (or later) depending on your current branch
- Backup current SONiC configuration using the configuration backup feature
- Download the appropriate fixed version (4.1.6 for 4.1.x branch or 4.2.2 for 4.2.x branch) from Dell support portal
- Verify the image integrity using checksums provided by Dell
- Schedule maintenance window as upgrade requires network disruption
- Upload the new image to the switch using the SONiC software installation command
- Reboot the switch to apply the new version
- Verify successful boot and confirm version number
- Validate that critical services are operational and connectivity is restored
