CVE-2024-2420
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 · uneditedLenelS2 NetBox access control and event monitoring system was discovered to contain Hardcoded Credentials in versions prior to and including 5.6.1 which allows an attacker to bypass authentication requirements.
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 · moderate confidenceLenelS2 NetBox access control and event monitoring system contains hardcoded credentials embedded in the software code or configuration that allow attackers to bypass normal authentication mechanisms. An unauthenticated remote attacker can exploit these credentials to gain administrative access to the access control system, potentially allowing physical access controlOverride, event monitoring manipulation, and network pivoting.

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.
-
Identify NetBox versionLog into the NetBox administrative interface and navigate to the About or System Information page, or check the version displayed on the login page. Alternatively, consult system documentation or release notes for the installed instance.Affected if The installed version is lower than 5.6.2 (for example, 5.6.1, 5.5.x, or earlier)
-
Confirm management interface exposureReview network firewall rules and access control lists to determine whether the NetBox web management interface (typically ports 80/443 or custom HTTP/HTTPS ports) is reachable from untrusted or external network segments.Affected if The management interface is accessible from untrusted networks or the internet without VPN or additional authentication barriers
-
Audit administrative user accountsWithin the NetBox administration panel, review the list of all administrative-level accounts for any unfamiliar or unauthorized users that may indicate exploitation using the hardcoded credentials.Affected if Unexpected administrative accounts exist that were not created by your organization
-
Check for unauthorized configuration changesReview system logs, event logs, and audit trails for administrative actions performed at unexpected times, from unexpected IP addresses, or involving changes to access control rules, door schedules, or system settings that you did not initiate.Affected if Administrative actions appear in logs that were not performed by legitimate administrators
You are affected if your NetBox version is below 5.6.2 AND the management interface is network-accessible to untrusted parties, as this combination enables unauthenticated attackers to exploit the hardcoded credentials for administrative access.
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 · scoped5.6.2
Update NetBox to a version beyond 5.6.1 when a patch is released by LenelS2. If immediate patching is not possible, restrict network exposure of the NetBox management interface to trusted networks and implement additional authentication layers such as VPN access or MFA.
LenelS2 NetBox version 5.6.2
- 1. Review the official LenelS2 NetBox upgrade documentation before proceeding
- 2. Create a complete backup of the current NetBox configuration and database
- 3. Download LenelS2 NetBox version 5.6.2 from the official LenelS2 or Carrier support portal
- 4. Apply the upgrade following the vendor's documented upgrade procedure for NetBox
- 5. After upgrade, verify that the hardcoded credentials vulnerability has been addressed by attempting to authenticate with the previously known hardcoded credentials (they should no longer work)
- 6. Confirm normal system operation and access control functionality after the upgrade
