Summary

Details

Impact

Skipper prior to version v0.13.236 is vulnerable to server-side request forgery (SSRF). An attacker can exploit a vulnerable version of proxy to access the internal metadata server or other unauthenticated URLs by adding an specific header (X-Skipper-Proxy) to the http request.

Patches

The problem was patched in version https://github.com/zalando/skipper/releases/tag/v0.13.237. Users need to upgrade to skipper >=v0.13.237.

Workarounds

Use dropRequestHeader("X-Skipper-Proxy") filter
