CVE-2019-1923


A vulnerability in Cisco Small Business SPA500 Series IP Phones could allow a physically proximate attacker to execute arbitrary commands on the device. The vulnerability is due to improper input validation in the device configuration interface. An attacker could exploit this vulnerability by accessing the configuration interface, which may require a password, and then accessing the device's physical interface and inserting a USB storage device. A successful exploit could allow the attacker to execute arbitrary commands on the device in an elevated security context. At the time of publication, this vulnerability affected Cisco Small Business SPA500 Series IP Phones firmware releases 7.6.2SR5 and prior.


Security Impact Summary

This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.6, 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 20 products from cisco, from cisco, from cisco and 17 others, organizations running these solutions should prioritize assessment and patching.

Historical Context

First disclosed in 2019, 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.

How SecUtils Interprets This CVE

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.
