TITLE

Cisco NX-OS Authorization vulnerabilities in software

Trust: 0.8

sources: JVNDB: JVNDB-2019-002448

DESCRIPTION

A vulnerability in the user account management interface of Cisco NX-OS Software could allow an authenticated, local attacker to gain elevated privileges on an affected device. The vulnerability is due to an incorrect authorization check of user accounts and their associated Group ID (GID). An attacker could exploit this vulnerability by taking advantage of a logic error that will permit the use of higher privileged commands than what is necessarily assigned. A successful exploit could allow an attacker to execute commands with elevated privileges on the underlying Linux shell of an affected device. Nexus 7000 and 7700 Series Switches are affected in versions prior to 6.2(22), 8.2(3), and 8.3(2). Nexus 3000 Series Switches are affected in versions prior to 7.0(3)I7(4). Nexus 3500 Platform Switches are affected in versions prior to 7.0(3)I7(4). Nexus 3600 Platform Switches are affected in versions prior to 7.0(3)F3(5). Nexus 9000 Series Switches-Standalone are affected in versions prior to 7.0(3)I7(4). Nexus 9500 R-Series Line Cards and Fabric Modules are affected in versions prior to 7.0(3)F3(5). Cisco NX-OS There is an authorization vulnerability in the software.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Cisco NX-OS Software is prone to local privilege-escalation vulnerability. This issue is being tracked by Cisco Bug IDs CSCvi53896, CSCvk70990, CSCvm35213, and CSCvm35215
