CWE-347 : Improper Verification of Cryptographic Signature
The product does not verify, or incorrectly verifies, the cryptographic signature for data. 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.) Does not properly verify signatures for "trusted" entities. Insufficient verification allows spoofing. Insufficient verification allows spoofing. Accepts a configuration file without a Message Integrity Check (MIC) signature.
