Denial of Service Vulnerability in Cisco Unified Communications Products

CVE-2023-20259

Summary

A vulnerability exists within an improperly secured API endpoint across various Cisco Unified Communications Products. An unauthenticated remote attacker could exploit this flaw by sending a specially crafted HTTP request. This could result in excessive CPU utilization, leading to potential delays in call processing and affecting access to the web-based management interface. This API is not meant for device management and its exploitation could result in a denial of service condition. Fortunately, once the attack ceases, the affected devices are designed to recover automatically without needing manual intervention.
