CVE-2023-22372Network attack vector

Remote data alteration via unenforced message integrity

Published May 3, 2023 · Updated Jan 29, 2025

Improper message-integrity enforcement in F5 BIG-IP Edge Client 7.2.2 through 7.2.4 allows remote attackers to alter connection data. During pre-connection processing, the client fails to ensure that a received message was not modified in transit; F5 has not disclosed the specific message or validation routine. Reachability is limited to pre-connection network exchanges, and the reported consequence is data alteration without disclosure or service interruption.
