CWE-1048: Invokable Control Element with Large Number of Outward Calls

Source-backed guidance

Additional facts reviewed against primary or authoritative security sources.

Detect imprecise mappings involving CWE-1048

Review mappings to CWE-1048, Invokable Control Element with Large Number of Outward Calls, with MITRE's mapping and navigation criteria. Flag any selection that points to a View or Category, remains at a higher abstraction than the available evidence supports, or ignores relevant parent, child, peer, and alternative entries. Treat those findings as mapping-quality defects, correct them before publication, and retain the comparison trail for repeatable audits.

Prevent CWE-1048 through an SSDF control plan

Use NIST SSDF practices to make prevention of CWE-1048, Invokable Control Element with Large Number of Outward Calls, an explicit development outcome. Translate the CWE definition into security requirements and design constraints, choose safer implementation patterns and toolchain checks, and define acceptance evidence before release. Feed every confirmed occurrence back into the requirements, design review, and coding rules so the same root cause is removed across the product rather than patched in one location.

Triage CWE-1048 against known exploitation evidence

Use CISA's Known Exploited Vulnerabilities catalog to test whether a vulnerability mapped to CWE-1048, Invokable Control Element with Large Number of Outward Calls, has evidence of exploitation in the wild. Confirm the CVE-to-CWE root-cause mapping independently before attaching the example, then capture the affected product, required action, and remediation deadline. A missing KEV match is not evidence that the weakness is unexploited, and a KEV entry must not be generalized to every occurrence of this CWE.

Use MITRE taxonomy anchors to review Invokable Control Element with Large Number of Outward Calls

Recorded impacts include Reduce Maintainability, and Increase Analytical Complexity; related weaknesses include CWE-710. Use these source-defined anchors to turn CWE-1048 into implementation, review, and verification checks for the affected component.

Validate CWE-1048 with root-cause mapping checks

Apply MITRE's root-cause mapping quick tips to CWE-1048, Invokable Control Element with Large Number of Outward Calls. Confirm the finding describes the causal weakness rather than an impact or attack pattern, compare the abstraction and mapping notes with plausible alternatives, and have a second reviewer challenge the selection. Preserve the evidence and reasoning so recurring defects can be measured against one consistent identifier.

Frequently Asked Questions

What is CWE-1048: Invokable Control Element with Large Number of Outward Calls?+

CWE-1048: Invokable Control Element with Large Number of Outward Calls is a Common Weakness Enumeration (CWE) entry maintained by MITRE. The code contains callable control elements that contain an excessively large number of references to other application objects external to the context of the callable, i.e. a Fan-Out value that is excessively large. While the interpretation of "excessively large Fan-Out value" may vary for each product or developer, CISQ recommends a default of 5 referenced objects.

What are the security consequences of Invokable Control Element with Large Number of Outward Calls?+

If exploited, CWE-1048 (Invokable Control Element with Large Number of Outward Calls) it can compromise Other, leading to outcomes such as Reduce Maintainability and Increase Analytical Complexity.

Which programming languages are affected by Invokable Control Element with Large Number of Outward Calls?+

CWE-1048 commonly affects Not Language-Specific. Note that weaknesses are often language-agnostic patterns, so secure coding practices apply broadly.

What is the difference between a CWE and a CVE?+

A CWE (Common Weakness Enumeration) like CWE-1048 describes a category of software weakness — the underlying flaw type. A CVE (Common Vulnerabilities and Exposures) identifies a specific, real-world vulnerability in a particular product. In short, a CWE is the kind of mistake, and a CVE is an instance of that mistake being found in software.
