CVE-2025-20161 is a command injection vulnerability affecting Cisco Nexus 3000 and 9000 Series Switches in standalone NX-OS mode. An authenticated, local attacker with Administrator credentials can exploit insufficient validation during the software upgrade process by installing a crafted image. This allows for arbitrary command execution on the underlying operating system with root privileges, though the CVSS score of 5.1 indicates a medium severity with low impact on confidentiality and high impact on integrity. There is currently no public exploit code available, no evidence of active exploitation, and minimal community discussion or media coverage.
