Overview

CVE-2023-20229 is a high-severity vulnerability. It was published on August 16, 2023 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

A vulnerability in the CryptoService function of Cisco Duo Device Health Application for Windows could allow an authenticated, local attacker with low privileges to conduct directory traversal attacks and overwrite arbitrary files on an affected system.

This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by executing a directory traversal attack on an affected host. A successful exploit could allow an attacker to use a cryptographic key to overwrite arbitrary files with SYSTEM-level privileges, resulting in a denial of service (DoS) condition or data loss on the affected system.

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.
