Server-Side Request Forgery
CWE-918
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.
We track 1,600 vulnerabilities of this type. 100% are rated high or critical, and the average CVSS score is 8.2. 26 have been exploited in real attacks.
How this weakness is prevented
- Implementation Operation: 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.
- Implementation Operation: 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.
