CVE-2024-20440 (GCVE-0-2024-20440)
Vulnerability from cvelistv5 – Published: 2024-09-04 16:28 – Updated: 2025-04-01 21:47Summary
A vulnerability in Cisco Smart Licensing Utility could allow an unauthenticated, remote attacker to access sensitive information.
This vulnerability is due to excessive verbosity in a debug log file. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to obtain log files that contain sensitive data, including credentials that can be used to access the API.
