Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Start learningUpgrade org.springframework.boot:spring-boot-actuator-autoconfigure
to version 3.3.11, 3.4.5 or higher.
Affected versions of this package are vulnerable to Improper Input Validation via the EndpointRequest.to()
function that creates a matcher for null/**
if the actuator endpoint, for which the EndpointRequest
has been created, is disabled or not exposed.
Note:
This is only exploitable if all of the following conditions are met:
EndpointRequest.to()
has been used in a Spring Security chain configuration;
The endpoint which EndpointRequest
references is disabled or not exposed via web;
Your application handles requests to /null
and this path needs protection.
This can be mitigated by either:
Making sure that the endpoint to which EndpointRequest.to()
is referring to is enabled and exposed via web;
Make sure that you don't handle requests to /null
.
