An attacker discovers that an identity provider performs partial checks of incoming user attributes for single sign-on. Which technique best helps them obtain unauthorized access?
Create a fake login site to capture employee credentials
Submit repeated guesses on the login page
Exploit injection flaws to pass crafted commands
Change the user attributes so they appear privileged, then reuse them to gain entry
Changing the attributes in the single sign-on data can fool the partial checks, granting a higher level of privilege. Repeated guesses, injection flaws, or deceptive websites emphasize other routes rather than using weak attribute verification to appear more privileged.
