CWE-554: ASP.NET Misconfiguration: Not Using Input Validation Framework

Source-backed guidance

Additional facts reviewed against primary or authoritative security sources.

Verify controls for CWE-554 with SSDF evidence

Use NIST SSDF verification and vulnerability-response practices to detect CWE-554, ASP.NET Misconfiguration: Not Using Input Validation Framework, throughout the product lifecycle. Derive review questions, static or dynamic checks, and negative tests from the CWE's causal behavior; define the components and lifecycle stages each check covers; and retain findings with enough evidence to distinguish the root cause from symptoms and impacts. Track escapes and false negatives, then improve the verification plan after every confirmed occurrence.

Address ASP.NET Misconfiguration: Not Using Input Validation Framework during Architecture and Design

MITRE associates mitigation with Architecture and Design; recorded impacts include Unexpected State; related weaknesses include CWE-1173. Use these source-defined anchors to turn CWE-554 into implementation, review, and verification checks for the affected component.

Triage CWE-554 against known exploitation evidence

Use CISA's Known Exploited Vulnerabilities catalog to test whether a vulnerability mapped to CWE-554, ASP.NET Misconfiguration: Not Using Input Validation Framework, 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.

Apply precise root-cause mapping to CWE-554

Apply MITRE's full root-cause mapping guidance when using CWE-554, ASP.NET Misconfiguration: Not Using Input Validation Framework. Separate weakness language from attacker prerequisites and technical impact, check the entry's abstraction and vulnerability-mapping notes, and prefer the most specific Base or Variant supported by the evidence. Record the rejected alternatives and require an independent review before the mapping is used for remediation trends or program metrics.

Validate CWE-554 with root-cause mapping checks

Apply MITRE's root-cause mapping quick tips to CWE-554, ASP.NET Misconfiguration: Not Using Input Validation Framework. 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-554: ASP.NET Misconfiguration: Not Using Input Validation Framework?+

CWE-554: ASP.NET Misconfiguration: Not Using Input Validation Framework is a Common Weakness Enumeration (CWE) entry maintained by MITRE. The ASP.NET application does not use an input validation framework.

What are the security consequences of ASP.NET Misconfiguration: Not Using Input Validation Framework?+

If exploited, CWE-554 (ASP.NET Misconfiguration: Not Using Input Validation Framework) it can compromise Integrity, leading to outcomes such as Unexpected State.

How do you prevent or mitigate ASP.NET Misconfiguration: Not Using Input Validation Framework?+

Recommended mitigations for CWE-554 include: Use the ASP.NET validation framework to check all program input before it is processed by the application. Example uses of the validation framework include checking to ensure that: Phone number fields contain only valid characters in phone numbers Boolean values are only "T" or "F" Free-form strings are of a reasonable length and composition

Which programming languages are affected by ASP.NET Misconfiguration: Not Using Input Validation Framework?+

CWE-554 commonly affects ASP.NET. 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-554 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.
