Understanding the Weakness (CWE)

Confidentiality

Technical Impact: Read Application Data

Integrity

Technical Impact: Execute Unauthorized Code or Commands

Access Control

Technical Impact: Bypass Protection Mechanism

By providing URLs to unexpected hosts or ports, attackers can make it appear that the server is sending the request, possibly bypassing access controls such as firewalls that prevent the attackers from accessing the URLs directly. The server can be used as a proxy to conduct port scanning of hosts in internal networks, use other URLs such as that can access documents on the system (using file://), or use other protocols such as gopher:// or tftp://, which may provide greater control over the contents of requests.
