A vulnerability in the USB-modem code of Cisco IOS XE Software running on Cisco ASR 920 Series Aggregation Services Routers could allow an authenticated, local attacker to overwrite arbitrary files on the underlying operating system of an affected device. The vulnerability is due to improper input validation of the platform usb modem command in the CLI of the affected software. An attacker could exploit this vulnerability by modifying the platform usb modem command in the CLI of an affected device. A successful exploit could allow the attacker to overwrite arbitrary files on the underlying operating system of an affected device. Cisco Bug IDs: CSCvf10783.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 4.4, requiring local system access to exploit with relatively low complexity without requiring user interaction . The vulnerability impacts integrity (unauthorized modifications), for affected systems. Impacting 10 products from cisco, from cisco, from cisco and 7 others, 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.
