Technical description

Microweber CMS through 2.0.20 contains a server-side template injection vulnerability that allows authenticated administrators to achieve arbitrary OS command execution by injecting Twig expressions into mail templates. Attackers can exploit the unsandboxed Twig environment in TwigView::render(), which lacks SandboxExtension or a SecurityPolicy, to inject malicious expressions such as filter('system') into mail template bodies stored unsanitized in the database, causing automatic payload execution on each subsequent application event that triggers a mail dispatch.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
