STIX 2.1

Exploitation Summary

EIP tracks 1 public exploit for CVE-2024-41107. PoCs published by d0rb. A Nuclei detection template is also available.

AI-analyzed exploit summary The repository contains a functional Python exploit for CVE-2024-41107, which targets an authentication bypass vulnerability in Apache CloudStack's SAML implementation. The exploit generates unsigned SAML responses to gain unauthorized access to user accounts.

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