Impact

An issue in DigestAuthProvider.verify:
The uri parameter in the client's Authorization: Digest … response was not checked against the actual request URL. A captured Digest authentication response could be replayed against any other URL served by the same realm, breaking the per-request-URL binding the Digest scheme assumes.
Who is affected: any application using http4k-security-digest for HTTP Digest authentication. The bug has been present since DigestAuthProvider was introduced (commit 8a52b615b1, 2021).

Patches

LineFixed inEdition
v6.x (Community)6.50.0.0Community
v5.x (LTS)5.42.0.0Enterprise — contact enterprise@http4k.org (if Digest auth is present in your v5.x line)
v4.x (LTS)4.51.0.0Enterprise — contact enterprise@http4k.org (if Digest auth is present in your v4.x line)
The fix:
  • Rejects credentials whose uri parameter does not match the request URL.

Workarounds

For deployments that cannot upgrade immediately:
  • URI binding gap: place Digest auth behind a reverse proxy that pins requests to a single URL.
