NVD Entry

DVLData Validation (DVL) class – Data are validated (syntax check) or sanitized (escape, filter, repair) improperly.
SanitizeSanitize operation – Modify data (neutralize/escape, filter/remove, repair/add symbols) to make it valid (well-formed).
Code BugCode Bug type – Defect in the implementation of the operation – proper operands over an improper operation. A first cause for the chain of weaknesses underlying a software security vulnerability. Must be fixed to resolve the vulnerability.
   Missing CodeMissing Code bug - The operation is entirely absent.
Injection Final ErrorInjection exploitable error type – An exploitable or undefined system behavior caused by 'code separation' data validation bugs.
   Source Code InjectionSource Code Injection exploitable error – Maliciously inserted new code (incl. with <> elements) into an input used as a part of an executing application code.
Operation AttributeDefinition
MechanismMechanism operation attribute type – Shows how the buggy/faulty operation code is performed.
   FormatFormat operation attribute – The operation is via a policy based on syntax format (e.g., defined via regular expression).
Source CodeSource Code operation attribute type – Shows where the buggy/faulty operation code is in software or firmware.
   CodebaseCodebase operation attribute – The operation is in the programmer's code - in the application itself.
Execution SpaceExecution Space operation attribute type – Shows where the buggy/faulty operation code is running or with what privilege level.
   LocalLocal operation attribute – The bugged code runs in an environment with access control policy with limited (local user) permission.
Operand AttributeDefinition
Data StateData State operand attribute type operand attribute – Shows where the data come from.
   StoredStored operand attribute – Data are from a permanent storage (e.g., file, database on a storage device); they are at rest.
