A vulnerability in the restricted shell of the Cisco Identity Services Engine (ISE) that is accessible via SSH could allow an authenticated, local attacker to run arbitrary CLI commands with elevated privileges. The vulnerability is due to incomplete input validation of the user input for CLI commands issued at the restricted shell. An attacker could exploit this vulnerability by authenticating to the targeted device and executing commands that could lead to elevated privileges. An attacker would need valid user credentials to the device to exploit this vulnerability. The vulnerability affects the following Cisco Identity Services Engine (ISE) products running Release 1.4, 2.0, 2.0.1, 2.1.0: ISE, ISE Express, ISE Virtual Appliance. Cisco Bug IDs: CSCve74916.
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 7.8, requiring local system access to exploit with relatively low complexity without requiring user interaction requiring only low-level privileges . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 3 products from cisco, from cisco, from cisco organizations running these solutions should prioritize assessment and patching.
First disclosed in 2017, this vulnerability was reported during a period defined by widespread IoT adoption challenges, mobile security concerns, and the emergence of advanced persistent threat (APT) techniques. Contemporary mitigation strategies focused on secure development practices and third-party component vetting.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For cisco's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
