Those involved can take a look at the content and mitigation methods of these two vulnerabilities below.

CVE-2022-22947: Code Injection Vulnerability

Severity : Critical

Vulnerability description : Applications using Spring Cloud Gateway are vulnerable to code injection when the Actuator endpoint is enabled, exposed, and unsecured. An attacker can maliciously create requests that allow arbitrary remote execution on a remote host.

Scope of influence :

The following versions of Spring Cloud Gateway are affected:

  • 3.1.0

  • 3.0.0 to 3.0.6

  • other old versions

Mitigation method :

Users of affected versions can remediate by the following actions.

  • 3.1.x users should upgrade to 3.1.1+

  • 3.0.x users should upgrade to 3.0.7+

  • If the Actuator endpoint is not required, it can be management.endpoint.gateway.enable:falsedisabled via configuration

  • If an Actuator endpoint is required, it should be secured with Spring Security

CVE-2022-22946: HTTP2 Insecure TrustManager
