Summary
The Red Hat Satellite /unattended/provision API endpoint in Foreman is vulnerable to an authentication bypass due to a semantic logic flaw in host_verifier.rb. The application verifies the database state of a provisioning token rather than its actual presence in the incoming HTTP request.
Risk Assessment
Because a host actively undergoing provisioning has an unexpired token in the database, the valid_host_token? method evaluates to true, granting access to the kickstart template even without a token in the URL.
Recommendation
Update Foreman/Satellite to a patched version that correctly verifies the token's presence in the HTTP request.
Other vulnerabilities in Foreman
See all- CVE-2015-5246High
The LDAP Authentication functionality in Foreman might allow remote attackers with knowledge of old passwords to gain access via vectors involving the password lifetime period in Active Directory.
- CVE-2016-4996High
In Foreman before 6.2, when the SSH service is enabled on discovered nodes, discovery-debug displays the root password in plaintext in the system journal during login.
- CVE-2015-5152High
Foreman versions from 1.1 to before 1.9.0-RC1 do not redirect HTTP requests to HTTPS when the require_ssl setting is enabled. This allows remote attackers to obtain user credentials via a man-in-the-middle attack.
- CVE-2017-7505High
Foreman since version 1.5 is vulnerable to an incorrect authorization check, allowing users with user management permissions assigned to certain organizations to perform all operations granted by these permissions on administrator user objects outside their scope.
- CVE-2016-4475High
The Organization and Locations APIs and UIs in Foreman before 1.11.4 and 1.12.x before 1.12.0-RC3 allow remote authenticated users to bypass organization and location restrictions, enabling (a) reading, (b) editing, or (c) deleting arbitrary organizations or locations.
- CVE-2013-0210High
The smart proxy Puppet run API in Foreman before 1.2.0 allows remote attackers to execute arbitrary commands via vectors related to escaping and Puppet commands.
- CVE-2013-0171High
Foreman before 1.1 allows remote attackers to execute arbitrary code via a crafted YAML object to the (1) fact or (2) report import API.
- CVE-2012-5648High
Multiple SQL injection vulnerabilities in Foreman before 1.0.2 allow remote attackers to execute arbitrary SQL commands via unspecified parameters in search.rb or puppetclass.rb, related to the search mechanism.
- CVE-2026-96659Critical
A flaw in Foreman allows an authenticated user with low-level Viewer permissions to cause unauthorized information disclosure by submitting requests to template preview endpoints. The user can access sensitive data such as host root passwords. Under insecure configurations with Safemode disabled, the flaw may also allow arbitrary command execution as the Foreman system account.
- CVE-2026-107203Medium
An incorrect authorization flaw has been found in network interface handling in the Foreman package. The domain and subnet interface API checks only that the caller holds a host permission, but does not apply the search limit on that permission. A low-privileged attacker can read interfaces of hosts they are not allowed to view, and if they have edit permissions, they can modify those interfaces.
Original NVD description (English source)
A flaw was found in Foreman. The Red Hat Satellite /unattended/provision API endpoint is vulnerable to an authentication bypass due to a semantic logic flaw in host_verifier.rb. The application verifies the database state of a provisioning token rather than its actual presence in the incoming HTTP request. Because a host actively undergoing provisioning has an unexpired token in the database, the server's valid_host_token? method evaluates to true, granting access to the kickstart template even if the requester provides no token at all in the URL.
