CVE-2022-23170 Detail

Current Description

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.

Base Score:  9.8 CRITICAL
Vector:  CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

NVD Analysts use publicly available information to associate vector strings and CVSS scores. We also display any CVSS information provided within the CVE List from the CNA.

Note: It is possible that the NVD CVSS may not match that of the CNA. The most common reason for this is that publicly available information does not provide sufficient detail or that information simply was not available at the time the CVSS vector string was assigned.
