CWE-304: Missing Critical Step in Authentication
The product implements an authentication technique, but it skips a step that weakens the technique.
How it's found
Missing Critical Step in Authentication 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.
Authentication techniques should follow the algorithms that define them exactly, otherwise authentication can be bypassed or more easily subjected to brute force attacks.
Consequences
- Bypass Protection Mechanism, Gain Privileges or Assume Identity, Read Application Data, Execute Unauthorized Code or Commands: This weakness can lead to the exposure of resources or functionality to unintended actors, possibly providing attackers with sensitive information or allowing attackers to execute arbitrary code.
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.
