CVE-2024-20323
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 · uneditedA vulnerability in Cisco Intelligent Node (iNode) Software could allow an unauthenticated, remote attacker to hijack the TLS connection between Cisco iNode Manager and associated intelligent nodes and send arbitrary traffic to an affected device. This vulnerability is due to the presence of hard-coded cryptographic material. An attacker in a man-in-the-middle position between Cisco iNode Manager and associated deployed nodes could exploit this vulnerability by using the static cryptographic key to generate a trusted certificate and impersonate an affected device. A successful exploit could allow the attacker to read data that is meant for a legitimate device, modify the startup configuration of an associated node, and, consequently, cause a denial of service (DoS) condition for downstream devices that are connected to the affected node.
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 confidenceThis vulnerability in Cisco iNode Software stems from hard-coded cryptographic keys embedded in the firmware. An attacker positioned as a man-in-the-middle can extract these static keys, generate trusted certificates, and impersonate legitimate intelligent nodes. This allows interception of TLS-protected traffic, modification of node startup configurations, and potential denial of service to downstream devices.

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 Cisco Inode installationLocate Cisco Inode software on the system or network inventory and determine its version number through the software's built-in version command, About screen, or system management interfaceAffected if The installed version is any version prior to 4.0.0
-
Identify Cisco Inode Manager installationLocate Cisco Inode Manager software on the system or network inventory and determine its version number through the software's built-in version command, About screen, or system management interfaceAffected if The installed version is any version prior to 24.1
-
Confirm firmware contains hard-coded keysIf the product is in the affected version range, inspect the firmware image or binary for embedded static cryptographic keys - this typically requires access to the firmware file itself or extraction toolsAffected if Hard-coded static cryptographic keys are present in the deployed firmware
A user is affected if they are running Cisco Inode below version 4.0.0 or Cisco Inode Manager below version 24.1, as these versions contain the hard-coded cryptographic keys that enable MITM attacks.

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 · scoped4.0.024.1
Apply the vendor patch when available and rotate all cryptographic material used in the iNode infrastructure. Until patched, network segmentation and strict access controls may help limit MITM attack surfaces.
Inode: 4.0.0 or later; Inode Manager: 24.1 or later
- 1. Identify all Cisco Intelligent Node (iNode) devices and Cisco iNode Manager instances in the environment
- 2. Document current version numbers of all affected devices (Inode and Inode Manager)
- 3. Review Cisco release notes and security advisories at sec.cloudapps.cisco.com for version 4.0.0 (Inode) and version 24.1 (Inode Manager)
- 4. Schedule a maintenance window for the upgrade
- 5. Back up current configurations for all iNode and iNode Manager devices
- 6. Upgrade Cisco iNode Manager to version 24.1 or later
- 7. Upgrade all Cisco iNode devices to version 4.0.0 or later
- 8. After upgrade, verify that TLS connections between iNode Manager and nodes are re-established using new certificates
