Description

In case Cacheservice was configured to use a sproxyd object-storage backend, it would follow HTTP redirects issued by that backend. An attacker with access to a local or restricted network with the capability to intercept and replay HTTP requests to sproxyd (or who is in control of the sproxyd service) could perform a server-side request-forgery attack and make Cacheservice connect to unexpected resources. We have disabled the ability to follow HTTP redirects when connecting to sproxyd resources. No publicly available exploits are known.

• CWE-918Server-Side Request Forgery (SSRF)The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
