CVE-2025-20308

Root command execution via crafted CLI parameters

Published Jul 2, 2025 · Updated Feb 26, 2026

OS command injection in Cisco Spaces Connector 3 allows local users with spacesadmin access to execute arbitrary commands as root. A specific, undisclosed Connector CLI command applies insufficient restrictions to crafted parameters before operating-system command execution. Exploitation requires local authentication as the high-privilege spacesadmin user and grants root-level access to read or modify data, with no reported service interruption.
