Attack profile from CVSS 3.1 · CISA ADP. Fix status from CNA. Impact type from CWE-770.

Summary

In api-gateway versions from 1.5.4 through 1.7.3, the default rate-limit key resolver ClientIpKeyResolver uses the leftmost X-Forwarded-For value as the client key. That value comes from the client and is not checked against a trusted-proxy list (CWE-807). A remote attacker with low privileges can send a different header value on each request to obtain a new rate-limit bucket each time, which bypasses request-rate limiting on routes that use the shipped default configuration.

Description from the CNA

In `api-gateway` versions till `1.7.3`, The default rate-limit key resolver, `ClientIpKeyResolver`, derives the per-client bucket key from the leftmost element of the `X-Forwarded-For` request header. That element is supplied by the originating HTTP client and is not validated against any trusted-proxy list. A single attacker can therefore obtain an unlimited number of independent rate-limit buckets — one per unique header value — and completely bypass the gateway's request-rate limiting on every route that uses the shipped default configuration.
