CVSS: 10.0EPSS: 52%CPEs: 25EXPL: 32CVE-2020-1472 – Microsoft Netlogon Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-1472
An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC). An attacker who successfully exploited the vulnerability could run a specially crafted application on a device on the network. To exploit the vulnerability, an unauthenticated attacker would be required to use MS-NRPC to connect to a domain controller to obtain domain administrator access. Microsoft is addressing the vulnerability in a phased two-part rollout. These updates address the vulnerability by modifying how Netlogon handles the usage of Netlogon secure channels. For guidelines on how to manage the changes required for this vulnerability and more information on the phased rollout, see How to manage the changes in Netlogon secure channel connections associated with CVE-2020-1472 (updated September 28, 2020). When the second phase of Windows updates become available in Q1 2021, customers will be notified via a revision to this security vulnerability. If you wish to be notified when these updates are released, we recommend that you register for the security notifications mailer to be alerted of content changes to this advisory.

CVSS: 6.5EPSS: 0%CPEs: 17EXPL: 0CVE-2019-14907 – samba: Crash after failed character conversion at log level 3 or above
https://notcve.org/view.php?id=CVE-2019-14907
All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with "log level = 3" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless). Todas las versiones de samba 4.9.x anteriores a 4.9.18, 4.10.x anteriores a 4.10.12 y 4.11.x anteriores a 4.11.5, presentan un problema donde si se configura con "log level = 3" (o superior), la cadena obtenida desde el cliente, luego de una conversión de caracteres fallida, es impresa. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00055.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14907 https://lists.debian.org/debian-lts-announce/2021/05/msg00023.html https://lists.debian.org/debian-lts-announce/2023/09/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4ACZVNMIFQGGXNJPMHAVBN3H2U65FXQY https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GQ6U65I2K23YJC4FESW477WL55TU3PPT https: • CWE-125: Out-of-bounds Read •

CVSS: 6.1EPSS: 0%CPEs: 13EXPL: 1CVE-2019-3870
https://notcve.org/view.php?id=CVE-2019-3870
A vulnerability was found in Samba from version (including) 4.9 to versions before 4.9.6 and 4.10.2. During the creation of a new Samba AD DC, files are created in a private subdirectory of the install location. This directory is typically mode 0700, that is owner (root) only access. However in some upgraded installations it will have other permissions, such as 0755, because this was the default before Samba 4.8. Within this directory, files are created with mode 0666, which is world-writable, including a sample krb5.conf, and the list of DNS names and servicePrincipalName values to update. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-3870 https://bugzilla.samba.org/show_bug.cgi?id=13834 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6354GALK73CZWQKFUG7AWB6EIEGFMF62 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JTJVFA3RZ6G2IZDTVKLHRMX6QBYA4GPA https://support.f5.com/csp/article/K20804356 https://www.samba.org/samba/security/CVE-2019-3870.html https://www.synology.com/security/advisory/Synology_SA_19 • CWE-276: Incorrect Default Permissions •
