CVE-2025-27084Network attack vector

Browser script execution via captive portal reflection

Published Apr 8, 2025 · Updated Apr 9, 2025

Reflected XSS in the captive portal of HPE Aruba Networking AOS allows remote attackers to execute script in a victim's browser. HPE identifies the captive portal as the affected locus but does not disclose which request value is reflected or how output encoding fails. Exploitation requires access to the affected interface and yields script execution only in the browser's interface context; HPE requires low privileges, while NVD models an unauthenticated crafted link and victim interaction.
