CVE-2021-22899Known exploitationNetwork attack vector

Authenticated code execution via Windows resource profiles

Published May 27, 2021 · Updated Oct 21, 2025

Command injection in Pulse Connect Secure before 9.1R11.4 allows remote authenticated users to execute code via Windows File Resource Profiles. Pulse Secure identifies that feature but has not published the affected function or how profile input reaches an operating-system command. A valid account and access to the feature are required; successful injection executes attacker-controlled commands on the gateway.
