CVE-2021-3565 – tpm2-tools: fixed AES wrapping key in tpm2_import
https://notcve.org/view.php?id=CVE-2021-3565
A flaw was found in tpm2-tools in versions before 5.1.1 and before 4.3.2. tpm2_import used a fixed AES key for the inner wrapper, potentially allowing a MITM attacker to unwrap the inner portion and reveal the key being imported. The highest threat from this vulnerability is to data confidentiality. Se ha encontrado un fallo en tpm2-tools en versiones anteriores a 5.1.1 y versiones anteriores a la 4.3.2. La función tpm2_import usaba una clave AES fija para el contenedor inner, permitiendo potencialmente a un atacante MITM desenvolver la parte interna y revelar la clave que está siendo importada. La mayor amenaza de esta vulnerabilidad es la confidencialidad de los datos A flaw was found in tpm2-tools. tpm2_import used a fixed AES key for the inner wrapper, potentially allowing a MITM attacker to unwrap the inner portion and reveal the key being imported. • https://bugzilla.redhat.com/show_bug.cgi?id=1964427 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ESY6HRYUKR5ZG2K5QAJQC5S6HMKZMFK7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XK5M7I66PBXSN663TSLAZ3V6TWWFCV7C https://access.redhat.com/security/cve/CVE-2021-3565 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-665: Improper Initialization CWE-798: Use of Hard-coded Credentials •
CVE-2021-3551 – pki-server: Dogtag installer "pkispawn" logs admin credentials into a world-readable log file
https://notcve.org/view.php?id=CVE-2021-3551
A flaw was found in the PKI-server, where the spkispawn command, when run in debug mode, stores admin credentials in the installation log file. This flaw allows a local attacker to retrieve the file to obtain the admin password and gain admin privileges to the Dogtag CA manager. The highest threat from this vulnerability is to confidentiality. Se ha encontrado un fallo en el servidor PKI, donde el comando spkispawn, cuando es ejecutado en modo de depuración, almacena las credenciales de administrador en el archivo de registro de la instalación. Este fallo permite a un atacante local recuperar el archivo para obtener la contraseña de administrador y alcanzar privilegios de administrador en el administrador de Dogtag CA. • https://bugzilla.redhat.com/show_bug.cgi?id=1959971 https://access.redhat.com/security/cve/CVE-2021-3551 • CWE-312: Cleartext Storage of Sensitive Information •
CVE-2021-3560 – Red Hat Polkit Incorrect Authorization Vulnerability
https://notcve.org/view.php?id=CVE-2021-3560
It was found that polkit could be tricked into bypassing the credential checks for D-Bus requests, elevating the privileges of the requestor to the root user. This flaw could be used by an unprivileged local attacker to, for example, create a new local administrator. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se ha detectado que polkit podía ser engañado para omitir las comprobaciones de credenciales para las peticiones de D-Bus, elevando los privilegios del solicitante al usuario root. Este fallo podría ser usado por un atacante local no privilegiado para, por ejemplo, crear un nuevo administrador local. • https://www.exploit-db.com/exploits/50011 https://github.com/secnigma/CVE-2021-3560-Polkit-Privilege-Esclation https://github.com/RicterZ/CVE-2021-3560-Authentication-Agent https://github.com/hakivvi/CVE-2021-3560 https://github.com/WinMin/CVE-2021-3560 https://github.com/0dayNinja/CVE-2021-3560 https://github.com/AssassinUKG/Polkit-CVE-2021-3560 https://github.com/chenaotian/CVE-2021-3560 https://github.com/BizarreLove/CVE-2021-3560 https://github.com/cpu0x00/CVE-2021-3560 • CWE-754: Improper Check for Unusual or Exceptional Conditions CWE-863: Incorrect Authorization •
