CVE-2022-36663: Deploy Cloud Native Gluu 4.3
Gluu Oxauth before v4.4.1 allows attackers to execute blind SSRF (Server-Side Request Forgery) attacks via a crafted request_uri parameter.
****request_uri blocklist and allowlist implemented to enhance security****
The request_uri Authorization Request parameter enables OpenID Connect requests to be passed by reference, rather than by value (see the spec). However, when implemented as written in the spec, the request_uri could be used to launch an SSRF (Server-Side Request Forgery) attack against the IDP. To mitigate this risk, we’ve implemented both a request_uri blocklist and a request_uri allowlist that are configurable in the Gluu Server OpenID Provider JSON configuration.
