Background
org.springframework.cloud:spring-cloud-function-context is a Maven package that provides functionality for Spring Cloud Function. It allows users to define and execute lightweight, single-purpose functions in a serverless environment. This package is widely used in Java applications that leverage Spring Cloud Function for their serverless architecture. However, versions 3.1.6, 3.2.2, and older unsupported versions of this package are vulnerable to a code injection vulnerability when using routing functionality.
Vulnerability Detail
The vulnerability arises from the ability for a user to provide a specially crafted SpEL (Spring Expression Language) as a routing-expression. This can lead to remote code execution and unauthorized access to local resources. An attacker can exploit this vulnerability by manipulating the routing-expression to execute arbitrary code on the server hosting the application. This can result in a complete compromise of the application and potentially the underlying system. The severity of this vulnerability is rated as CRITICAL with a CVSS score of 9.8.
How To Fix
Fixed versions by release line
The minimum fixed version depends on the release line you run.
-
< 3.1.73.1.7 -
>= 3.2.0, < 3.2.33.2.3
