CVE-2017-12251 — Cisco Cloud Services Platform 2100 security vulnerability

Critical CVSS 9.9

A vulnerability in the web console of the Cisco Cloud Services Platform (CSP) 2100 could allow an authenticated, remote attacker to interact maliciously with the services or virtual machines (VMs) operating remotely on an affected CSP device. The vulnerability is due to weaknesses in the generation of certain authentication mechanisms in the URL of the web console. An attacker could exploit this vulnerability by browsing to one of the hosted VMs' URLs in Cisco CSP and viewing specific patterns that control the web application's mechanisms for authentication control. An exploit could allow the attacker to access a specific VM on the CSP, which causes a complete loss of the system's confidentiality, integrity, and availability. This vulnerability affects Cisco Cloud Services Platform (CSP) 2100 running software release 2.1.0, 2.1.1, 2.1.2, 2.2.0, 2.2.1, or 2.2.2. Cisco Bug IDs: CSCve64690.

Matched remediation archetype

Authentication bypass and missing authentication

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

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
