Medium CVSS 5.5

A vulnerability in the CLI of Cisco IOS XE Software could allow an authenticated, low-privileged, local attacker to access WLAN configuration details including passwords. This vulnerability is due to improper privilege checks. An attacker could exploit this vulnerability by using the show and show tech wireless CLI commands to access configuration details, including passwords. A successful exploit could allow the attacker to access configuration details that they are not authorized to access.

Matched remediation archetype

Privilege escalation and unsafe privilege management

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

Check exposure

  • Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
  • Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
  • Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.

Remediate safely

  • Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
  • Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
  • Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
