CVE-2017-7551 – 389-ds-base: Password brute-force possible for locked account due to different return codes
https://notcve.org/view.php?id=CVE-2017-7551
389-ds-base version before 1.3.5.19 and 1.3.6.7 are vulnerable to password brute-force attacks during account lockout due to different return codes returned on password attempts. 389-ds-base en su versión anterior a 1.3.5.19 y 1.3.6.7 es vulnerable a ataques de fuerza bruta de contraseñas durante un bloqueo de cuenta debido a los diferentes códigos de retorno que se devuelven durante los intentos de contraseña. A flaw was found in the way 389-ds-base handled authentication attempts against locked accounts. A remote attacker could potentially use this flaw to continue password brute-forcing attacks against LDAP accounts, thereby bypassing the protection offered by the directory server's password lockout policy. • https://access.redhat.com/errata/RHSA-2017:2569 https://pagure.io/389-ds-base/issue/49336 https://access.redhat.com/security/cve/CVE-2017-7551 https://bugzilla.redhat.com/show_bug.cgi?id=1477669 • CWE-209: Generation of Error Message Containing Sensitive Information CWE-640: Weak Password Recovery Mechanism for Forgotten Password •
CVE-2017-2668 – 389-ds-base: Remote crash via crafted LDAP messages
https://notcve.org/view.php?id=CVE-2017-2668
389-ds-base before versions 1.3.5.17 and 1.3.6.10 is vulnerable to an invalid pointer dereference in the way LDAP bind requests are handled. A remote unauthenticated attacker could use this flaw to make ns-slapd crash via a specially crafted LDAP bind request, resulting in denial of service. 389-ds-base en versiones anteriores a la 1.3.5.17 y 1.3.6.10 es vulnerable a una desreferencia de puntero inválido en la forma en la que se gestionan las peticiones LDAP. Un atacante remoto no autenticado podría emplear este error para hacer que ns-slapd se cierre inesperadamente mediante una petición bind LDAP especialmente manipulada que resulta en una denegación de servicio (DoS). An invalid pointer dereference flaw was found in the way 389-ds-base handled LDAP bind requests. A remote unauthenticated attacker could use this flaw to make ns-slapd crash via a specially crafted LDAP bind request, resulting in denial of service. • http://www.securityfocus.com/bid/97524 https://access.redhat.com/errata/RHSA-2017:0893 https://access.redhat.com/errata/RHSA-2017:0920 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-2668 https://pagure.io/389-ds-base/issue/49220 https://access.redhat.com/security/cve/CVE-2017-2668 https://bugzilla.redhat.com/show_bug.cgi?id=1436575 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-476: NULL Pointer Dereference •
CVE-2016-0741 – 389-ds-base: worker threads do not detect abnormally closed connections causing DoS
https://notcve.org/view.php?id=CVE-2016-0741
slapd/connection.c in 389 Directory Server (formerly Fedora Directory Server) 1.3.4.x before 1.3.4.7 allows remote attackers to cause a denial of service (infinite loop and connection blocking) by leveraging an abnormally closed connection. slapd/connection.c en 389 Directory Server (anteriormente Fedora Directory Server) 1.3.4.x en versiones anteriores a 1.3.4.7 permite a atacantes remotos causar una denegación de servicio (bucle infinito y bloqueo de conexion) aprovechándose de una conexión cerrada de manera anómala. An infinite-loop vulnerability was discovered in the 389 directory server, where the server failed to correctly handle unexpectedly closed client connections. A remote attacker able to connect to the server could use this flaw to make the directory server consume an excessive amount of CPU and stop accepting connections (denial of service). • http://directory.fedoraproject.org/docs/389ds/releases/release-1-3-4-7.html http://rhn.redhat.com/errata/RHSA-2016-0204.html http://www.oracle.com/technetwork/topics/security/linuxbulletinjan2016-2867209.html http://www.securityfocus.com/bid/82343 https://fedorahosted.org/389/changeset/cd45d032421b0ecf76d8cbb9b1c3aeef7680d9a2 https://fedorahosted.org/389/ticket/48412 https://access.redhat.com/security/cve/CVE-2016-0741 https://bugzilla.redhat.com/show_bug.cgi?id=1299416 • CWE-399: Resource Management Errors CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2015-3230
https://notcve.org/view.php?id=CVE-2015-3230
389 Directory Server (formerly Fedora Directory Server) before 1.3.3.12 does not enforce the nsSSL3Ciphers preference when creating an sslSocket, which allows remote attackers to have unspecified impact by requesting to use a disabled cipher. 389 Directory Server (anteriormente Fedora Directory Server) en versiones anteriores a 1.3.3.12 no hace cumplir la preferencia nsSSL3Ciphers cuando crean un sslSocket, lo que permite a atacantes remotos tener un impacto no especificado mediante la petición de utilizar un cifrado deshabilitado. • http://directory.fedoraproject.org/docs/389ds/releases/release-1-3-3-12.html http://lists.fedoraproject.org/pipermail/package-announce/2015-October/168985.html https://bugzilla.redhat.com/show_bug.cgi?id=1230996 https://fedorahosted.org/389/ticket/48194 • CWE-254: 7PK - Security Features •
CVE-2014-8112 – 389-ds-base: password hashing bypassed when "nsslapd-unhashed-pw-switch" is set to off
https://notcve.org/view.php?id=CVE-2014-8112
389 Directory Server 1.3.1.x, 1.3.2.x before 1.3.2.27, and 1.3.3.x before 1.3.3.9 stores "unhashed" passwords even when the nsslapd-unhashed-pw-switch option is set to off, which allows remote authenticated users to obtain sensitive information by reading the Changelog. 389 Directory Server 1.3.1.x, 1.3.2.x anterior a 1.3.2.27, y 1.3.3.x anterior a 1.3.3.9 almacena contraseñas sin estar en hash incluso cuando la opción nsslapd-unhashed-pw-switch está configurado como apagado (off), lo que permite a usuarios remotosw autenticados obtener información sensible mediante la lectura del registro de cambios (Changelog). It was found that when the nsslapd-unhashed-pw-switch 389 Directory Server configuration option was set to "off", it did not prevent the writing of unhashed passwords into the Changelog. This could potentially allow an authenticated user able to access the Changelog to read sensitive information. • http://directory.fedoraproject.org/docs/389ds/releases/release-1-3-2-27.html http://directory.fedoraproject.org/docs/389ds/releases/release-1-3-3-9.html http://lists.fedoraproject.org/pipermail/package-announce/2015-March/153991.html http://rhn.redhat.com/errata/RHSA-2015-0416.html https://bugzilla.redhat.com/show_bug.cgi?id=1172729 https://access.redhat.com/security/cve/CVE-2014-8112 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-522: Insufficiently Protected Credentials •
