    Expression Language Injection

    Affected versions of this package are vulnerable to Expression Language Injection in the GatewayEvaluationContext method, which allows property modification that in turn enables code execution.

    Only Webflux applications are vulnerable, not WebMVC applications. Additionally, the following conditions must be true to render an application vulnerable:

    • Spring Boot actuator is a dependency.

    • The Spring Cloud Gateway Server Webflux actuator web endpoint is enabled via management.endpoints.web.exposure.include=gateway.

    How to fix Expression Language Injection?

    Upgrade org.springframework.cloud:spring-cloud-gateway-server to version 4.2.5, 4.3.1 or higher.

    Unintended Proxy or Intermediary ('Confused Deputy')

    Affected versions of this package are vulnerable to Unintended Proxy or Intermediary ('Confused Deputy') due to the improper validation of X-Forwarded-For and Forwarded headers forwarded from untrusted proxies. An attacker can manipulate the server's behavior by sending crafted headers from an untrusted proxy.

    Notes:

    1. The vulnerability was also fixed in version 4.0.12, a commercial version;

    2. The X-Forwarded-* and Forwarded header functionality will be disabled by default with the fix versions. If you require X-Forwarded-* or Forwarded header functionality, after upgrading you will need to set spring.cloud.gateway.trusted-proxies to a Java Regular Expression that specifies the proxies whose headers you trust. If you are using Spring Cloud Gateway Server MVC (only available from 4.1.x onward) set spring.cloud.gateway.mvc.trusted-proxies.

    How to fix Unintended Proxy or Intermediary ('Confused Deputy')?

    Upgrade org.springframework.cloud:spring-cloud-gateway-server to version 3.1.10, 4.1.8, 4.2.3 or higher.
