org.http4s/http4s-client_2.13org.http4s/http4s-client_2.13org.http4s/http4s-client_3The CookieJar client middleware decides whether to attach a cookie to an outgoing request using an unanchored substring test on the host and path, instead of the domain match specified by RFC6265 5.1.3. A cookie stored for example.com is therefore sent to any host whose name merely contains example.com (e.g. evilexample.com), leaking potentially sensitive cookies to an attacker-chosen host.
Impact
Disclosure of session and authentication cookies to an attacker-controlled host, enabling session hijack of the application's outbound calls.
Preconditions
- Application uses the
CookieJarclient middleware. - Application can be induced to make an outbound request to a host controlled by the attacker, where the hostname contains the targeted domain as a substring.
Workarounds
- Do not use the
CookieJarwith clients that fetch attacker-influenced URLs - Apply a separate
CookieJarper trusted origin.
