SAML XXE Vulnerability in Morpheus

CVE-2022-31261 · HIGH Severity

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

An XXE issue was discovered in Morpheus through 5.2.16 and 5.4.x through 5.4.4. A successful attack requires a SAML identity provider to be configured. In order to exploit the vulnerability, the attacker must know the unique SAML callback ID of the configured identity source. A remote attacker can send a request crafted with an XXE payload to invoke a malicious DTD hosted on a system that they control. This results in reading local files that the application has access to.
