A vulnerability in vpnva-6.sys for 32-bit Windows and vpnva64-6.sys for 64-bit Windows of Cisco AnyConnect Secure Mobility Client for Windows Desktop could allow an authenticated, local attacker to cause a denial of service (DoS) condition on an affected system. The vulnerability is due to improper validation of user-supplied data. An attacker could exploit this vulnerability by sending a malicious request to the application. A successful exploit could allow the attacker to cause a DoS condition on the affected system. Cisco Bug IDs: CSCvj47654.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 5.5, requiring local system access to exploit with relatively low complexity without requiring user interaction requiring only low-level privileges . The vulnerability impacts and availability (service disruption) for affected systems. Impacting 2 products from cisco, from microsoft 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.
