CWE-544: Missing Standardized Error Handling Mechanism
The product does not use a standardized method for handling errors throughout the code, which might introduce inconsistent error handling and resultant weaknesses.
How it's found
Missing Standardized Error Handling Mechanism is typically found by tracing untrusted input from where it enters the system to the point where it is used without the check or neutralization this weakness describes, combining manual code review with dynamic testing.
If the product handles error messages individually, on a one-by-one basis, this is likely to result in inconsistent error handling. The causes of errors may be lost. Also, detailed information about the causes of an error may be unintentionally returned to the user.
Consequences
- Quality Degradation, Unexpected State, Varies by Context
Mitigations
- Architecture and Design: define a strategy for handling errors of different severities, such as fatal errors versus basic log events. Use or create built-in language features, or an external package, that provides an easy-to-use API and define coding standards for the detection and handling of errors.
Where this fits in a TurboPentest engagement
This weakness is not covered by the automated black-box pentest. IntegSec pentesters cover it in a manual engagement.
