Official description

Adobe Document Service allows an attacker with administrator privileges to send a crafted request from a vulnerable web application. It is usually used to target internal systems behind firewalls that are normally inaccessible to an attacker from the external network, resulting in a Server-Side Request Forgery vulnerability. On successful exploitation, the attacker can read or modify any file and/or make the entire system unavailable.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Server-Side Request Forgery

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.

How developers prevent this class of flaw

  • If there is a known list of applications, IP, hostname, and/or domains to which the product is allowed to communicate, then use allowlists to ensure that outgoing requests are restricted to these known entities. The allowlists could be in the application code or possibly enforced by firewalls or network segmentation.
  • If the product is expected to be able to connect to arbitrary IP addresses or domains, consider using a denylist that includes private network addresses, internal domain names, etc. The denylist could be in the application code or possibly enforced by firewalls or network segmentation.
