CVSS: 7.8EPSS: 0%CPEs: 8EXPL: 0CVE-2015-8325 – openssh: privilege escalation via user's PAM environment and UseLogin=yes
https://notcve.org/view.php?id=CVE-2015-8325
The do_setup_env function in session.c in sshd in OpenSSH through 7.2p2, when the UseLogin feature is enabled and PAM is configured to read .pam_environment files in user home directories, allows local users to gain privileges by triggering a crafted environment for the /bin/login program, as demonstrated by an LD_PRELOAD environment variable. La función do_setup_env en session.c en sshd en OpenSSH hasta la versión 7.2p2, cuando la funcionalidad UseLogin está activa y PAM está configurado para leer archivos .pam_environment en directorios home de usuario, permite a usuarios locales obtener privilegios desencadenando un entorno manipulado para el programa /bin/login, según lo demostrado por una variable de entorno LD_PRELOAD. It was discovered that the OpenSSH sshd daemon fetched PAM environment settings before running the login program. In configurations with UseLogin=yes and the pam_env PAM module configured to read user environment settings, a local user could use this flaw to execute arbitrary code as root. • http://rhn.redhat.com/errata/RHSA-2016-2588.html http://rhn.redhat.com/errata/RHSA-2017-0641.html http://www.debian.org/security/2016/dsa-3550 http://www.securityfocus.com/bid/86187 http://www.securitytracker.com/id/1036487 https://anongit.mindrot.org/openssh.git/commit/?id=85bdcd7c92fe7ff133bbc4e10a65c91810f88755 https://bugzilla.redhat.com/show_bug.cgi?id=1328012 https://cert-portal.siemens.com/productcert/pdf/ssa-412672.pdf https://people.canonical.com/~ubuntu-security/cve/2015&#x • CWE-264: Permissions, Privileges, and Access Controls CWE-863: Incorrect Authorization •

CVSS: 7.5EPSS: 3%CPEs: 11EXPL: 1CVE-2016-2118 – samba: SAMR and LSA man in the middle attacks
https://notcve.org/view.php?id=CVE-2016-2118
The MS-SAMR and MS-LSAD protocol implementations in Samba 3.x and 4.x before 4.2.11, 4.3.x before 4.3.8, and 4.4.x before 4.4.2 mishandle DCERPC connections, which allows man-in-the-middle attackers to perform protocol-downgrade attacks and impersonate users by modifying the client-server data stream, aka "BADLOCK." Las implementaciones de protocolo MS-SAMR y MS-LSAD en Samba 3.x y 4.x en versiones anteriores a 4.2.11, 4.3.x en versiones anteriores a 4.3.8 y 4.4.x en versiones anteriores a 4.4.2 no maneja correctamente las conexiones DCERPC, lo que permite a atacantes man-in-the-middle llevar a cabo ataques de desactualización de protocolo y hacerse pasar por usuarios modificando el flujo de datos cliente-servidor, también conocida como "BADLOCK". A protocol flaw, publicly referred to as Badlock, was found in the Security Account Manager Remote Protocol (MS-SAMR) and the Local Security Authority (Domain Policy) Remote Protocol (MS-LSAD). Any authenticated DCE/RPC connection that a client initiates against a server could be used by a man-in-the-middle attacker to impersonate the authenticated user against the SAMR or LSA service on the server. As a result, the attacker would be able to get read/write access to the Security Account Manager database, and use this to reveal all passwords or any other potentially sensitive information in that database. • https://github.com/nickanderson/cfengine-CVE-2016-2118 http://badlock.org http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182185.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182272.html http://lists.fedoraproject.org/pipermail/package-announce/2016-April/182288.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00021.html http://lists.opensuse.org/opensuse-security- • CWE-254: 7PK - Security Features CWE-300: Channel Accessible by Non-Endpoint •
