Last modified

CVE-2020-3365 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. A vulnerability in the directory permissions of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, remote attacker to perform a directory traversal attack on a limited set of restricted directories. The vulnerability is due to a flaw in the logic that governs directory permissions. EPSS estimates a 1.61% chance of exploitation in the next 30 days.

Description

A vulnerability in the directory permissions of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an authenticated, remote attacker to perform a directory traversal attack on a limited set of restricted directories. The vulnerability is due to a flaw in the logic that governs directory permissions. An attacker could exploit this vulnerability by using capabilities that are not controlled by the role-based access control (RBAC) mechanisms of the software. A successful exploit could allow the attacker to overwrite files on an affected device.
