CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.

CWE Name CVEs Why this control addresses it
CWE-829Inclusion of Functionality from Untrusted Control Sphere259Defining acceptable mobile code technologies and authorizing their use prevents inclusion of functionality from untrusted control spheres.
CWE-494Download of Code Without Integrity Check243Authorizing and controlling mobile code requires verifying origin and integrity before download/execution, directly preventing this weakness.
CWE-913Improper Control of Dynamically-Managed Code Resources108Requiring explicit authorization and ongoing control of mobile code implements proper management of dynamically loaded code resources.
CWE-506Embedded Malicious Code83Monitoring mobile code usage enables detection of embedded malicious code delivered through allowed mobile code channels.
CWE-830Inclusion of Web Functionality from an Untrusted Source12Restricting mobile code technologies and monitoring their use blocks web functionality (e.g., scripts) loaded from untrusted sources.
