На связи команда Безопасности Wildberries — сегодня расскажем, как построить PAM на основе Teleport. Эту статью по мотивам нашего доклада на PHDays для вас подготовили руководитель департамента информационной безопасности и противодействия мошенничеству Wildberries Антон…
Teleport v3.2.2, Teleport v3.5.6-rc6, and Teleport v3.6.3-b2 was discovered to contain an information leak via the /user/get-role-list web interface.
Yubico pam-u2f before 1.1.1 has a logic issue that, depending on the pam-u2f configuration and the application used, could lead to a local PIN bypass. This issue does not allow user presence (touch) or cryptographic signature verification to be bypassed, so an attacker would still need to physically possess and interact with the YubiKey or another enrolled authenticator. If pam-u2f is configured to require PIN authentication, and the application using pam-u2f allows the user to submit NULL as the PIN,…
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.
