CVE-2018-15379 — Cisco Prime Infrastructure security vulnerability

Critical CVSS 9.8

A vulnerability in which the HTTP web server for Cisco Prime Infrastructure (PI) has unrestricted directory permissions could allow an unauthenticated, remote attacker to upload an arbitrary file. This file could allow the attacker to execute commands at the privilege level of the user prime. This user does not have administrative or root privileges. The vulnerability is due to an incorrect permission setting for important system directories. An attacker could exploit this vulnerability by uploading a malicious file by using TFTP, which can be accessed via the web-interface GUI. A successful exploit could allow the attacker to run commands on the targeted application without authentication.

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.
