CVE-2024-20490

Cleartext credential disclosure via tech-support log

Published Oct 2, 2024 · Updated Oct 2, 2024

Information disclosure in affected Cisco NDFC and Cisco NDO releases allows local users with a tech support file to read HTTP proxy credentials. An internal logging function writes configured HTTP proxy server administrator credentials in clear text into a log bundled in generated tech support files. Exploitation requires access to a generated support file; the disclosed credentials permit administration of the proxy used for external connectivity.
