GHSA-4QC6-W2F8-X2PC

Vulnerability from github – Published: 2022-04-22 00:24 – Updated: 2024-04-03 23:05

Details

Yubico PAM Module before 2.10 performed user authentication when 'use_first_pass' PAM configuration option was not used and the module was configured as 'sufficient' in the PAM configuration. A remote attacker could use this flaw to circumvent common authentication process and obtain access to the account in question by providing a NULL value (pressing Ctrl-D keyboard sequence) as the password string.

Severity ?

9.8 (Critical)
