Spring Cloud Function - Remote Code Execution (CVE-2022-22963)

Spring Cloud Function is affected by a Remote Code Execution, located in the /functionRouter endpoint. The root cause of this vulnerability is the lack of validation in the spring.cloud.function.routing-expression parameter by the Cloud Function, which can be used for code injection.The affected versions are 3.2.2 and 3.1.6 or lower.

Sniper can gain unauthenticated Remote Code Execution on the target system and extract multiple artefacts as evidence.

The risk exists that a remote unauthenticated attacker can fully compromise the server in order to steal confidential information, install ransomware, or pivot to the internal network.

Upgrade the Spring Cloud Gateway to a version higher than 3.1.6, 3.2.2.
