CVE-2023-22787Network attack vector

Service interruption via undisclosed PAPI flaw

Published May 8, 2023 · Updated Jan 31, 2025

Denial of service in PAPI services on affected Aruba access points allows remote attackers to interrupt normal access-point operation. HPE identifies only a service reached through PAPI and has not published the specific malformed input or faulty operation that causes the interruption. No credentials or user interaction are required; successful exploitation disrupts the access point, with no reported data disclosure or modification.
