ESA-2016-096: EMC Celerra, VNX1, VNX2 and VNXe SMB NTLM Authentication Weak Nonce Vulnerability
-BEGIN PGP SIGNED MESSAGE- Hash: SHA256 ESA-2016-096: EMC Celerra, VNX1, VNX2 and VNXe SMB NTLM Authentication Weak Nonce Vulnerability EMC Identifier: ESA-2016-096 CVE Identifier: CVE-2016-0917 Severity Rating: CVSS v3 Base Score: 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) Affected products: EMC Software: EMC VNX2 Operating Environment for File versions prior to 8.1.9.155 EMC Software: EMC VNX1 Operating Environment for File versions prior to 7.1.80.3 EMC Software: EMC VNXe3200 Operating Environment prior to 3.1.5.8711957 EMC Software: EMC VNXe3100/3150/3300 Operating Environment prior to 2.4.4.22638 EMC Software: EMC Celerra (all supported versions) Summary: SMB implementation in EMC Celerra, VNX1, VNX2, and VNXe are affected by an NTLM authentication weak nonce vulnerability that may potentially be exploited by malicious users to compromise the affected system. Details: An unauthenticated remote attacker may potentially exploit the NTLM challenge-response authentication protocol causing the server to generate duplicate challenges/nonces to potentially access the SMB service of the target system under the credentials of an authorized user. Depending on the privileges of the user, the attacker may be able to obtain and modify files on the target system and execute arbitrary code. This issue is similar to the Microsoft Windows SMB implementation issue that is described under CVE-2010-0231 (https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2010-0231). Resolution: The following releases contain resolutions for this issue: EMC VNX2 Operating Environment for File 8.1.9.155 EMC VNX1 Operating Environment for File 7.1.80.3 EMC VNXe3200 Operating Environment 3.1.5.8711957 EMC VNXe3100/3150/3300 Operating Environment 2.4.4.22638 Dell EMC recommends all customers upgrade at the earliest opportunity. There is currently no plan to release fixes for EMC Celerra based on the current support lifecycle of the product. Workaround: Customers that are unable to upgrade should use Kerberos authentication instead of NTLM. Link to remedies: Registered EMC Support customers can download EMC VNX2, VNX1, and VNXe software from the EMC Online Support web site at https://support.emc.com.
