Overview

CVE-2021-1257 is a high-severity vulnerability. It was published on January 20, 2021 and has a CVSS 3.1 base score of 8.8 (HIGH).

Technical description

A vulnerability in the web-based management interface of Cisco DNA Center Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack to manipulate an authenticated user into executing malicious actions without their awareness or consent. The vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a web-based management user to follow a specially crafted link. A successful exploit could allow the attacker to perform arbitrary actions on the device with the privileges of the authenticated user. These actions include modifying the device configuration, disconnecting the user's session, and executing Command Runner commands.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
