TLS hijacking via hard-coded cryptographic key
Published Jul 17, 2024 · Updated Aug 1, 2024
Hard-coded keys in Cisco iNode Software 3.1.2 and earlier and iNode Manager 23.1 and earlier allow remote attackers to hijack TLS. A static private key lets a man-in-the-middle generate a trusted certificate, impersonate an iNode, and inject arbitrary traffic into the manager-to-node connection. Network-path access is required; successful exploitation reads node-bound data, alters node startup configuration, and can interrupt downstream service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
