A critical command injection vulnerability (CVE-2024-20432, CVSS 9.9) in Cisco Nexus Dashboard Fabric Controller allows authenticated low-privileged attackers to execute arbitrary commands via the REST API or web UI, granting network-admin privileges on managed devices. Affected versions are 12.0.0 through 12.2.1, and Cisco has released a fix in version 12.2.2. The vendor states there are no available workarounds for this flaw.
A vulnerability in the REST API and web UI of Cisco Nexus Dashboard Fabric Controller (NDFC) could allow an authenticated, low-privileged, remote attacker to perform a command injection attack against an affected device. This vulnerability is due to improper user authorization and insufficient validation of command arguments. An attacker could exploit this vulnerability by submitting crafted commands to an affected REST API endpoint or through the web UI. A successful exploit could allow the attacker to execute arbitrary commands on the CLI of a Cisco NDFC-managed device with network-admin privileges. Note: This vulnerability does not affect Cisco NDFC when it is configured for storage area network (SAN) controller deployment. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
