CWE-354 is Improper Validation of Integrity Check Value. The flaw arises when the product does not validate or incorrectly validates the integrity check values or "checksums" of a message. The database currently holds 66 vulnerabilities mapped to CWE-354 and none of them are in the CISA Known Exploited Vulnerabilities catalog.
A short verification protects the official data source and prevents automated AI abuse.

No vulnerability data in CISA KEV for CWE-354
The product does not validate or incorrectly validates the integrity check values or "checksums" of a message.
| Impact | Scope | Explanation |
|---|---|---|
| Modify Application Data, Other | Integrity, Other | Integrity checks usually use a secret key that helps authenticate the data origin. Skipping integrity checking generally opens up the possibility that new data from an invalid source can be injected. |
| Other | Integrity, Other | Data that is parsed and used may be corrupted. |
| Hide Activities, Other | Non-Repudiation, Other | Without a checksum check, it is impossible to determine if any changes have been made to the data after it was sent. |
| Method | Approach | Effectiveness |
|---|---|---|
| Automated Static Analysis | Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.) | - |
