TITLE

Microsoft Windows Netlogon Remote Protocol (MS-NRPC) uses insecure AES-CFB8 initialization vector

Trust: 0.8

sources: CERT/CC: VU#490028

DESCRIPTION

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. See Microsoft Technical Security Notifications. The Microsoft Windows Netlogon Remote Protocol (MS-NRPC) reuses a known, static, zero-value initialization vector (IV) in AES-CFB8 mode. plural Microsoft Windows The product contains an elevation of privilege vulnerability. Both Microsoft Windows and Microsoft Windows Server are products of Microsoft Corporation. Microsoft Windows is an operating system for personal devices. Microsoft Windows Server is a server operating system. Netlogon is a service used to register all SRV resource records for domain controllers. The following products and versions are affected: Microsoft Windows Server 2008 R2 SP1, Windows Server 2012, Windows Server 2012 R2, Windows Server 2016, Windows Server 2019, Windows Server 1903, Windows Server 1909, Windows Server 2004. A flaw was found in the way samba handled file and directory permissions. (CVE-2020-14318) A null pointer dereference flaw was found in Samba's winbind service. This flaw allows a local user to crash the winbind service, causing a denial of service. The highest threat from this vulnerability is to system availability. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-1472). 8) - aarch64, noarch, ppc64le, s390x, x86_64 3. The following packages have been upgraded to a later upstream version: samba (4.13.3).

This update provides the corresponding update for Ubuntu 14.04 ESM. Original advisory details: Tom Tervoort discovered that the Netlogon protocol implemented by Samba incorrectly handled the authentication scheme. This update fixes the issue by changing the "server schannel" setting to default to "yes", instead of "auto", which will force a secure netlogon channel. This may result in compatibility issues with older devices. A future update may allow a finer-grained control over this setting. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 ESM: samba 2:4.3.11+dfsg-0ubuntu0.14.04.20+esm9 In general, a standard system update will make all the necessary changes. See the following link for examples: https://www.samba.org/samba/security/CVE-2020-1472.html In addition, this update adds additional server checks for the protocol attack in the client-specified challenge to provide some protection when 'server schannel = no/auto' and avoid the false-positive results when running the proof-of-concept exploit. Description: Red Hat Gluster Storage is a software only scale-out storage solution that provides flexible and affordable unstructured data storage. It unifies data storage and infrastructure, increases performance, and improves availability and manageability to meet enterprise-level storage challenges. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied
