CVSS: 7.5EPSS: 5%CPEs: 38EXPL: 0CVE-2015-5300 – ntp: MITM attacker can force ntpd to make a step larger than the panic threshold
https://notcve.org/view.php?id=CVE-2015-5300
The panic_gate check in NTP before 4.2.8p5 is only re-enabled after the first change to the system clock that was greater than 128 milliseconds by default, which allows remote attackers to set NTP to an arbitrary time when started with the -g option, or to alter the time by up to 900 seconds otherwise by responding to an unspecified number of requests from trusted sources, and leveraging a resulting denial of service (abort and restart). La comprobación panic_gate en NTP anterior a versión 4.2.8p5 es solo habilitada nuevamente después del primer cambio al reloj del sistema que fue mayor que 128 milisegundos por defecto, permitiendo a los atacantes remotos fijar el NTP a un tiempo arbitrario cuando arranca con la opción -g, o alterar el tiempo hasta 900 segundos, de lo contrario por respuesta a un número no especificado de peticiones de fuentes de confianza y aprovechando una denegación de servicio resultante (anular y reiniciar). It was found that ntpd did not correctly implement the threshold limitation for the '-g' option, which is used to set the time without any restrictions. A man-in-the-middle attacker able to intercept NTP traffic between a connecting client and an NTP server could use this flaw to force that client to make multiple steps larger than the panic threshold, effectively changing the time to an arbitrary value at any time. • http://aix.software.ibm.com/aix/efixes/security/ntp_advisory5.asc http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170684.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/170926.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177507.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00060.html http://lists.opensuse.org/opensuse-security-announc • CWE-20: Improper Input Validation CWE-361: 7PK - Time and State •
CVSS: 10.0EPSS: 1%CPEs: 1EXPL: 0CVE-2015-1842 – openstack-puppet-modules: pacemaker configured with default password
https://notcve.org/view.php?id=CVE-2015-1842
The puppet manifests in the Red Hat openstack-puppet-modules package before 2014.2.13-2 uses a default password of CHANGEME for the pcsd daemon, which allows remote attackers to execute arbitrary shell commands via unspecified vectors. Puppet Manifests en el paquete openstack-puppet-modules de Red Hat anterior a 2014.2.13-2 utiliza una contraseño por defecto de CHANGEME para el demonio pcsd, lo que permite a atacantes remotos ejecutar comandos de shell arbitrarios a través de vectores no especificados. It was discovered that the puppet manifests, as provided with the openstack-puppet-modules package, would configure the pcsd daemon with a known default password. If this password was not changed and an attacker was able to gain access to pcsd, they could potentially run shell commands as root. • http://rhn.redhat.com/errata/RHSA-2015-0789.html http://rhn.redhat.com/errata/RHSA-2015-0791.html http://rhn.redhat.com/errata/RHSA-2015-0830.html http://rhn.redhat.com/errata/RHSA-2015-0831.html http://rhn.redhat.com/errata/RHSA-2015-0832.html http://www.securityfocus.com/bid/74049 https://bugzilla.redhat.com/show_bug.cgi?id=1201875 https://access.redhat.com/security/cve/CVE-2015-1842 • CWE-255: Credentials Management Errors CWE-798: Use of Hard-coded Credentials •
