Last modified

CVE-2018-0337 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. A vulnerability in the role-based access-checking mechanisms of Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands on an affected device. The vulnerability exists because the affected software lacks proper input and validation checks for certain file systems. EPSS estimates a 0.31% chance of exploitation in the next 30 days.

Description

A vulnerability in the role-based access-checking mechanisms of Cisco NX-OS Software could allow an authenticated, local attacker to execute arbitrary commands on an affected device. The vulnerability exists because the affected software lacks proper input and validation checks for certain file systems. An attacker could exploit this vulnerability by issuing crafted commands in the CLI of an affected device. A successful exploit could allow the attacker to cause other users to execute unwanted, arbitrary commands on the affected device. Cisco Bug IDs: CSCvd06339, CSCvd15698, CSCvd36108, CSCvf52921, CSCvf52930, CSCvf52953, CSCvf52976.
