Executive Summary

A critical vulnerability, CVE-2026-12647, has been identified in Ivanti Neurons for ITSM versions prior to 2026.2. This vulnerability allows a remote authenticated attacker to execute arbitrary code on the server, posing a significant risk to affected systems. The vulnerability has a CVSS score of 9.9, indicating a high severity level.

Technical Analysis

The vulnerability is classified as a Missing Authorization issue. The attack vector involves a remote authenticated attacker who can execute arbitrary code on the server. The root cause of this vulnerability is the lack of proper authorization checks, allowing an attacker to bypass normal access controls.

How It Gets Exploited

An attacker with remote authenticated access can exploit this vulnerability by sending a crafted request to the Ivanti Neurons for ITSM server. Specifically, the attacker would send a malicious request that takes advantage of the missing authorization checks, allowing them to execute arbitrary code on the server. This could involve sending a specially crafted API request or interacting with the application's web interface in a way that bypasses normal security checks. Upon successful exploitation, the attacker could achieve arbitrary code execution on the server, potentially leading to a complete compromise of the system.

Impact Assessment

Ivanti Neurons for ITSM versions prior to 2026.2 are affected by this vulnerability. An attacker who successfully exploits this vulnerability can execute arbitrary code on the server, which could lead to a range of impacts including data breaches, system compromise, and disruption of service. The CVSS score of 9.9 indicates a critical severity level, with high impacts on confidentiality, integrity, and availability.

Recommended Actions

To mitigate this vulnerability, it is essential to update Ivanti Neurons for ITSM to version 2026.2 or later. Additionally, administrators should monitor their systems for any suspicious activity and implement network segmentation or other security controls to limit the potential impact of a successful exploitation. It is also recommended to review and restrict access to the affected systems to prevent unauthorized access.
