CWE-1390: Weak Authentication
The product uses an authentication mechanism to restrict access to specific users or identities, but the mechanism does not sufficiently prove that the claimed identity is correct.
How it's found
Weak Authentication describes a general pattern rather than a single fixed bug. Testers use a mix of static analysis and manual code review to find where a target's code matches this pattern, then confirm exploitability by hand.
Attackers may be able to bypass weak authentication faster and/or with less effort than expected.
Consequences
- Read Application Data, Gain Privileges or Assume Identity, 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 even 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.
