CVE intelligence and bounded remediation

CVE-2019-15260 — Cisco Aironet 1540 Firmware security vulnerability

Critical CVSS 9.8

A vulnerability in Cisco Aironet Access Points (APs) Software could allow an unauthenticated, remote attacker to gain unauthorized access to a targeted device with elevated privileges. The vulnerability is due to insufficient access control for certain URLs on an affected device. An attacker could exploit this vulnerability by requesting specific URLs from an affected AP. An exploit could allow the attacker to gain access to the device with elevated privileges. While the attacker would not be granted access to all possible configuration options, it could allow the attacker to view sensitive information and replace some options with values of their choosing, including wireless network configuration. It would also allow the attacker to disable the AP, creating a denial of service (DoS) condition for clients associated with the AP.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

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

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
