CVE-2019-2684 – OpenJDK: Incorrect skeleton selection in RMI registry server-side dispatch handling (RMI, 8218453)
https://notcve.org/view.php?id=CVE-2019-2684
Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: RMI). Supported versions that are affected are Java SE: 7u211, 8u202, 11.0.2 and 12; Java SE Embedded: 8u201. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Java SE, Java SE Embedded accessible data. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets (in Java SE 8), that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00013.html http://www.openwall.com/lists/oss-security/2020/09/01/4 http://www.oracle.com/technetwork/security-advisory/cpuapr2019-5072813.html https://access.redhat.com/errata/RHBA-2019:0959 https://access.re •
CVE-2019-3842 – systemd - Lack of Seat Verification in PAM Module Permits Spoofing Active Session to polkit
https://notcve.org/view.php?id=CVE-2019-3842
In systemd before v242-rc4, it was discovered that pam_systemd does not properly sanitize the environment before using the XDG_SEAT variable. It is possible for an attacker, in some particular configurations, to set a XDG_SEAT environment variable which allows for commands to be checked against polkit policies using the "allow_active" element rather than "allow_any". En systemd anterior de la versión v242-rc4, fue encontrado que pam_systemd no sanea apropiadamente el entorno anterior usando la variable XDG_SEAT. Es posible que un atacante, en ciertas configuraciones particulares, establezca una variable de entorno XDG_SEAT que permita comprobar los comandos contra las políticas polkit utilizando el elemento "allow_active" en lugar de "allow_any". It was discovered that pam_systemd does not properly sanitize the environment before using the XDG_SEAT variable. • https://www.exploit-db.com/exploits/46743 http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00062.html http://packetstormsecurity.com/files/152610/systemd-Seat-Verification-Active-Session-Spoofing.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3842 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https:// • CWE-285: Improper Authorization CWE-863: Incorrect Authorization •
CVE-2019-3880 – samba: save registry file outside share as unprivileged user
https://notcve.org/view.php?id=CVE-2019-3880
A flaw was found in the way samba implemented an RPC endpoint emulating the Windows registry service API. An unprivileged attacker could use this flaw to create a new registry hive file anywhere they have unix permissions which could lead to creation of a new file in the Samba share. Versions before 4.8.11, 4.9.6 and 4.10.2 are vulnerable. Se encontró un fallo en la forma en que samba implementó RPC endpoint, que emula la API de servicios de registro de Windows. Un atacante sin privilegios podría usar este defecto para crear un nuevo archivo de registro hive en cualquier lugar que tenga permisos Unix, lo que podría llevar a la creación de un nuevo archivo en el recurso compartido de Samba. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00050.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00106.html https://access.redhat.com/errata/RHSA-2019:1966 https://access.redhat.com/errata/RHSA-2019:1967 https://access.redhat.com/errata/RHSA-2019:2099 https://access.redhat.com/errata/RHSA-2019:3582 https://access.redhat.com/security/cve/cve-2019-3880 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3880 https://lists.debian.org/d • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVE-2019-0217 – httpd: mod_auth_digest: access control bypass due to race condition
https://notcve.org/view.php?id=CVE-2019-0217
In Apache HTTP Server 2.4 release 2.4.38 and prior, a race condition in mod_auth_digest when running in a threaded server could allow a user with valid credentials to authenticate using another username, bypassing configured access control restrictions. En Apache HTTP Server 2.4 versión 2.4.38 y anteriores, una condición de carrera en mod_auth_digest cuando se ejecuta en un servidor multihilo podría permitir a un usuario con credenciales válidas autenticarse usando otro nombre de usuario, evitando las restricciones de control de acceso configuradas.

CVE-2019-0211 – Apache HTTP Server Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2019-0211
In Apache HTTP Server 2.4 releases 2.4.17 to 2.4.38, with MPM event, worker or prefork, code executing in less-privileged child processes or threads (including scripts executed by an in-process scripting interpreter) could execute arbitrary code with the privileges of the parent process (usually root) by manipulating the scoreboard. Non-Unix systems are not affected. En Apache HTTP Server 2.4, versiones 2.4.17 a 2.4.38, con el evento MPM, worker o prefork, el código ejecutándose en procesos hijo (o hilos) menos privilegiados (incluyendo scripts ejecutados por un intérprete de scripts en proceso) podría ejecutar código arbitrario con los privilegios del proceso padre (normalmente root) manipulando el marcador. Los sistemas que no son Unix no se ven afectados. A flaw was found in Apache where code executing in a less-privileged child process or thread could execute arbitrary code with the privilege of the parent process (usually root). • https://www.exploit-db.com/exploits/46676 http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00051.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00061.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00084.html http://packetstormsecurity.com/files/152386/Apache-2.4.38-Root-Privilege-Escalation.html http://packetstormsecurity.com/files/152415/Slackware-Security-Advisory-httpd-Updates.html http://packetstormsecurity.com/files/152441/CARPE-DIEM-Apache-2.4.x • CWE-250: Execution with Unnecessary Privileges CWE-416: Use After Free •
