A vulnerability in the CLI of the Cisco StarOS operating system for Cisco ASR 5000 Series Aggregation Services Routers could allow an authenticated, local attacker to perform a command injection attack on an affected system. The vulnerability is due to insufficient validation of commands that are supplied to certain configurations in the CLI of the affected operating system. An attacker could exploit this vulnerability by injecting crafted arguments into a vulnerable CLI command for an affected system. A successful exploit could allow the attacker to insert and execute arbitrary commands in the CLI of the affected system. To exploit this vulnerability, the attacker would need to authenticate to an affected system by using valid administrator credentials. Cisco Bug IDs: CSCvg29441.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.7, requiring local system access to exploit with relatively low complexity without requiring user interaction . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 6 products from cisco, from cisco, from cisco and 3 others, organizations running these solutions should prioritize assessment and patching.
First disclosed in 2018, 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.
