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 “false”, or upgrade to version 4.18.2.2, 4.19.1.0 or later, which addresses this issue.

This repository contains an exploit for the critical vulnerability identified as CVE-2024-41107 in Apache CloudStack. This vulnerability affects versions 4.5.0 through 4.18.2.1 and 4.19.0.0 through 4.19.0.2. The flaw lies within the Security Assertion Markup Language (SAML) authentication mechanism, allowing attackers to submit unsigned SAML responses to gain unauthorized access to user accounts and control over cloud resources.
