CVE-2019-15975Public exploitNetwork attack vector

Administrative authentication bypass via forged session token

Published Jan 6, 2020 · Updated Nov 15, 2024

Authentication bypass in Cisco Data Center Network Manager before 11.3(1) allows remote attackers to gain administrative REST API access. The REST API accepts session tokens encrypted with a static key shared across installations, allowing attackers to forge a valid token. Network access to the REST API is sufficient; a forged token permits arbitrary administrative API actions without valid credentials.
