CWE-924: Improper Enforcement of Message Integrity During Transmission in a Communication Channel

Source-backed guidance

Additional facts reviewed against primary or authoritative security sources.

Detect imprecise mappings involving CWE-924

Review mappings to CWE-924, Improper Enforcement of Message Integrity During Transmission in a Communication Channel, 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-924 through an SSDF control plan

Use NIST SSDF practices to make prevention of CWE-924, Improper Enforcement of Message Integrity During Transmission in a Communication Channel, 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-924 against known exploitation evidence

Use CISA's Known Exploited Vulnerabilities catalog to test whether a vulnerability mapped to CWE-924, Improper Enforcement of Message Integrity During Transmission in a Communication Channel, 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 Improper Enforcement of Message Integrity During Transmission in a Communication Channel

Recorded impacts include Gain Privileges or Assume Identity; related weaknesses include CWE-345. Use these source-defined anchors to turn CWE-924 into implementation, review, and verification checks for the affected component.

Validate CWE-924 with root-cause mapping checks

Apply MITRE's root-cause mapping quick tips to CWE-924, Improper Enforcement of Message Integrity During Transmission in a Communication Channel. 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-924: Improper Enforcement of Message Integrity During Transmission in a Communication Channel?+

CWE-924: Improper Enforcement of Message Integrity During Transmission in a Communication Channel is a Common Weakness Enumeration (CWE) entry maintained by MITRE. The product establishes a communication channel with an endpoint and receives a message from that endpoint, but it does not sufficiently ensure that the message was not modified during transmission. Attackers might be able to modify the message and spoof the endpoint by interfering with the data as it crosses the network or by redirecting the connection to a system under their control.

What are the security consequences of Improper Enforcement of Message Integrity During Transmission in a Communication Channel?+

If exploited, CWE-924 (Improper Enforcement of Message Integrity During Transmission in a Communication Channel) it can compromise Integrity and Confidentiality, leading to outcomes such as Gain Privileges or Assume Identity.

Which programming languages are affected by Improper Enforcement of Message Integrity During Transmission in a Communication Channel?+

CWE-924 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-924 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.
