Cisco iNode Software Vulnerability Could Allow Hijacking of TLS Connections and Denial of Service

CVE-2024-20323

What is CVE-2024-20323?

A vulnerability exists in Cisco Intelligent Node (iNode) Software that allows remote attackers to hijack TLS connections between Cisco iNode Manager and its associated intelligent nodes. This vulnerability arises from hard-coded cryptographic material, which enables an attacker positioned in a man-in-the-middle to exploit the static cryptographic key. By doing so, the attacker can create a trusted certificate, impersonating a legitimate device. This breach permits unauthorized access to sensitive data intended for the legitimate device, and an attacker can modify the startup configuration of affected nodes, potentially leading to a denial of service (DoS) condition for all downstream devices connected to the compromised node.
