CVE-2023-20259
CVSS 3.1 Score 7.5 of 10 (high)
Details
Summary
CVE-2023-20259 is a vulnerability affecting multiple Cisco Unified Communications Products. An unauthenticated, remote attacker can exploit this issue by sending a maliciously crafted HTTP request to a specific API endpoint. This vulnerability, resulting from improper API authentication and incomplete request validation, could lead to high CPU utilization, causing delays in call processing and impacting access to the web-based management interface. Although this API is not typically used for device management and unlikely to be employed in normal operations, a successful attack could result in a denial of service condition. Upon exploit termination, the device recovers automatically.
