CVE-2022-23170 — SysAid - Okta SSO integration - was found vulnerable to XML External Entity Injection vulnerability

Critical CVSS 9.8

SysAid - Okta SSO integration - was found vulnerable to XML External Entity Injection vulnerability. Any SysAid environment that uses the Okta SSO integration might be vulnerable. An unauthenticated attacker could exploit the XXE vulnerability by sending a malformed POST request to the identity provider endpoint. An attacker can extract the identity provider endpoint by decoding the SAMLRequest parameter's value and searching for the AssertionConsumerServiceURL parameter's value. It often allows an attacker to view files on the application server filesystem and interact with any back-end or external systems that the application can access. In some situations, an attacker can escalate an XXE attack to compromise the underlying server or other back-end infrastructure by leveraging the XXE vulnerability to perform server-side request forgery (SSRF) attacks.

Matched remediation archetype

XML external entity and unsafe XML processing

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

Check exposure

  • Inventory XML parsers used by APIs, file imports, office or image formats, identity protocols, feeds, and background jobs.
  • Determine whether document type declarations, external entities, XInclude, schemas, or network resolvers are enabled.
  • Map parser filesystem and network access and the sensitivity of documents it processes.

Remediate safely

  • Configure each parser to reject document type declarations and disable external entity, XInclude, and network resolution features.
  • Prefer a data format or hardened parser that does not support external resolution, and apply input size and depth limits.
  • Update affected XML libraries and centralize secure parser construction so callers cannot silently override it.
