Weaknesses (CWE)

CWE-829 Inclusion of Functionality from Untrusted Control Sphere

CWE-829 — Inclusion of Functionality from Untrusted Control Sphere: The product imports, requires, or includes executable functionality (such as a library) from a source that is outside of the intended control sphere.

[Architecture and Design] Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].
[Architecture and Design] When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs. For example, ID 1 could map to "inbox.txt" and ID 2 could map to "profile.txt". Features such as the ESAPI AccessReferenceMap [REF-45] provide this capability.
