Mitigation MIT-57
Strategy: Attack Surface Reduction
Ensure that critical variables are initialized before first use [REF-1485].
Mitigation
Strategy: Compilation or Build Hardening
Most compilers will complain about the use of uninitialized variables if warnings are turned on.
Mitigation
When using a language that does not require explicit declaration of variables, run or compile the software in a mode that reports undeclared or unknown variables. This may indicate the presence of a typographic error in the variable's name.
Mitigation
Strategy: Language Selection
Choose a language that is not susceptible to these issues.
Mitigation
Mitigating technologies such as safe string libraries and container abstractions could be introduced.
No CAPEC attack patterns related to this CWE.
