Concrete CMS (formerly concrete5) versions 8.5.6 and below and version 9.0.0 allow local IP importing causing the system to be vulnerable toa. SSRF attacks on the private LAN servers by reading files from the local LAN. An attacker can pivot in the private LAN and exploit local network appsandb.

Concrete CMS (formerly concrete5) versions below 8.5.7 has a SSRF mitigation bypass using DNS Rebind attack giving an attacker the ability to fetch cloud IAAS (ex AWS) IAM keys.To fix this Concrete CMS no longer allows downloads from the local network and specifies the validated IP when downloading rather than relying on DNS.Discoverer: Adrian Tiron from FORTBRIDGE ( https://www.fortbridge.co.uk/ )The Concrete CMS team gave this a CVSS 3.1 score of 3.5 AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:N/A:N . Please note that Cloud IAAS provider mis-configurations are not Concrete CMS vulnerabilities. A mitigation for this vulnerability is to make sure that the IMDS configurations are according to a cloud provider's best practices.This fix is also in Concrete version 9.0.0 Concrete CMS (antes concrete5) versiones anteriores a 8.5.7, presentan una omisión de mitigación de tipo SSRF usando un ataque DNS Rebind dando a un atacante la capacidad de conseguir claves IAM en la nube IAAS (ex AWS). Para corregir esto Concrete CMS ya no permite descargas desde la red local y especifica la IP comprobada cuando descarga en lugar de confiar en DNS.Discoverer: Adrian Tiron de FORTBRIDGE ( https://www.fortbridge.co.uk/ ).El equipo de Concrete CMS dio a esto una puntuación CVSS 3.1 de 3.5 AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:N/A:N . Por favor, tenga en cuenta que los errores de configuración de los proveedores de Cloud IAAS no son vulnerabilidades concretas de CMS. • https://documentation.concretecms.org/developers/introduction/version-history/857-release-notes https://hackerone.com/reports/1369312 • CWE-918: Server-Side Request Forgery (SSRF) •

A SSRF issue was discovered in Concrete CMS through 8.5.5. Users can access forbidden files on their local network. A user with permissions to upload files from external sites can upload a URL that redirects to an internal resource of any file type. The redirect is followed and loads the contents of the file from the redirected-to server. Files of disallowed types can be uploaded. • https://documentation.concretecms.org/developers/introduction/version-history/856-release-notes https://hackerone.com/reports/1102105 • CWE-918: Server-Side Request Forgery (SSRF) •
