Detailsinfo

A vulnerability, which was classified as problematic, was found in Cisco Intelligent Node Manager and Intelligent Node Software (the affected version unknown). Affected is an unknown part of the component TLS Connection Handler. The manipulation with an unknown input leads to a hard-coded key vulnerability. CWE is classifying the issue as CWE-321. The use of a hard-coded cryptographic key significantly increases the possibility that encrypted data may be recovered. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

A 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.

The advisory is shared for download at sec.cloudapps.cisco.com. This vulnerability is traded as CVE-2024-20323 since 11/08/2023. The exploitability is told to be difficult. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1600.001.

Upgrading eliminates this vulnerability.
