Weakness (CWE)
CWE-665: Improper Initialization
The product does not initialize or incorrectly initializes a resource.
How to prevent it (6 mitigations)
-
Requirements
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
For example, in Java, if the programmer does not explicitly initialize a variable, then the code could produce a compile-time error (if the variable is local) or automatically initialize the variable to the default value for the variable's type. In Perl, if explicit initialization is not performed, then a default value of undef is assigned, which is interpreted as 0, false, or an equivalent value depending on the context in which the variable is accessed.
-
Architecture and Design
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
-
Implementation
Explicitly initialize all your variables and other data stores, either during declaration or just before the first usage.
-
Implementation
Pay close attention to complex conditionals that affect initialization, since some conditions might not perform the initialization.
-
Implementation
Avoid race conditions (CWE-362) during initialization routines.
-
Build and Compilation
Run or compile your product with settings that generate warnings about uninitialized variables or data.
