CVE-2021-22887


A vulnerability in the BIOS of Pulse Secure (PSA-Series Hardware) models PSA5000 and PSA7000 could allow an attacker to compromise BIOS firmware. This vulnerability can be exploited only as part of an attack chain. Before an attacker can compromise the BIOS, they must exploit the device.


Security Impact Summary

This vulnerability carries a LOW severity rating with a CVSS v3.1 score of 2.3, requiring local system access to exploit with relatively low complexity without requiring user interaction . The vulnerability impacts limited integrity, for affected systems. Impacting 24 products from pulsesecure, from pulsesecure, from pulsesecure and 21 others, organizations running these solutions should prioritize assessment and patching.

Historical Context

Reported in 2021, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

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 pulsesecure'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.
