CVE-2024-20531 — Cisco Identity Services Engine security vulnerability

Medium CVSS 6.5

A vulnerability in the API of Cisco ISE could allow an authenticated, remote attacker to read arbitrary files on the underlying operating system of an affected device and conduct a server-side request forgery (SSRF) attack through an affected device. To exploit this vulnerability, the attacker would need valid Super Admin credentials. This vulnerability is due to improper handling of XML External Entity (XXE) entries when parsing XML input. An attacker could exploit this vulnerability by sending a crafted API request to an affected device. A successful exploit could allow the attacker to read arbitrary files on the underlying operating system or conduct an SSRF attack through the affected device.

Matched remediation archetype

Server-side request forgery and unintended proxying

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

Check exposure

  • Inventory server-side URL fetchers, webhooks, importers, previews, redirects, proxies, and protocol handlers reachable from untrusted input.
  • Map egress paths to internal services, metadata endpoints, loopback, private address space, and privileged control planes.
  • Review DNS resolution, redirect, proxy, credential-forwarding, and URL parsing behavior without requesting sensitive targets.

Remediate safely

  • Replace arbitrary destinations with named integrations or a strict allowlist of schemes, hosts, ports, and paths.
  • Resolve and validate every destination and redirect hop, then enforce egress policy independently of application checks.
  • Remove ambient credentials and sensitive headers from fetchers; apply response size, time, and content limits.
