Description

IBM DataPower Gateway 11.0.0.0 through 11.0.0.1 and IBM DataPower Gateway 10.5.0.0 through 10.5.0.21 and IBM DataPower Gateway 10.6.0.0 through 10.6.0.9 allows a race condition that results in improper isolation of request state when handling the built‑in X‑Client‑IP header. Under concurrent request processing, X‑Client‑IP values may be contaminated across requests, enabling IP spoofing and disclosure of other clients’ IP addresses.
