Medium CVSS 6.7

A vulnerability in Cisco Spaces Connector could allow an authenticated, local attacker to elevate privileges and execute arbitrary commands on the underlying operating system as root. This vulnerability is due to insufficient restrictions during the execution of specific CLI commands. An attacker could exploit this vulnerability by logging in to the Cisco Spaces Connector CLI as the spacesadmin user and executing a specific command with crafted parameters. A successful exploit could allow the attacker to elevate privileges from the spacesadmin user and execute arbitrary commands on the underlying operating system as root.

Command, code, expression, and template injection

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted values to process execution, interpreters, evaluators, template engines, dynamic imports, and administrative scripting features.
  • Determine whether the affected path is reachable across each trust boundary and which service account or host privilege it inherits.
  • Review configuration for optional execution features, unsafe compatibility modes, and shell invocation.

Remediate safely

  • Replace string-built commands or evaluated code with fixed operations and structured argument APIs that do not invoke a shell.
  • Use strict allowlists for operation identifiers and reject unexpected input before it reaches any interpreter.
  • Update the affected component and add inert regression tests covering metacharacters, encoding variants, and alternate request paths.
