CVE-2018-0392 — A vulnerability in the CLI of Cisco Policy Suite could allow an authenticated, local attacker to access files owned by another user

Medium CVSS 5.5

A vulnerability in the CLI of Cisco Policy Suite could allow an authenticated, local attacker to access files owned by another user. The vulnerability is due to insufficient access control permissions (i.e., World-Readable). An attacker could exploit this vulnerability by logging in to the CLI. An exploit could allow the attacker to access potentially sensitive files that are owned by a different user. Cisco Bug IDs: CSCvh18087.

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.
