CVE-2024-41107 Information

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. In such environments this can result in a complete compromise of the resources owned and/or accessible by a SAML enabled user-account.

Affected users are recommended to disable the SAML authentication plugin by setting the \saml2.enabled\ global setting to alse\ or upgrade to version 4.18.2.2 4.19.1.0 or later which addresses this issue.
