The vulnerability allows a remote user to list or overwrite files on the device.
The vulnerability exists due to insufficient validation of user-supplied input in a certain REST API endpoint of Cisco Data Center Network Manager (DCNM) Software. A remote user can send a specially crafted HTTP request to the system and list of overwrite arbitrary files on the system.
6) Improper Authorization (CVE-ID: CVE-2020-3540)
CWE-ID: CWE-285 - Improper Authorization
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote user to gain access to otherwise restricted functionality.
The vulnerability exists due to insufficient authorization checks in the web-based management interface of Cisco Data Center Network Manager (DCNM). A remote authenticated user can gain access to administrative functionality and view, modify, and delete data without proper authorization.
7) Improper Authorization (CVE-ID: CVE-2020-3539)
CWE-ID: CWE-285 - Improper Authorization
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green
