## Overview

Improper Neutralization of Special Elements Used in a Template Engine ('Server-Side Template Injection') in MacroScreenRenderer in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote authenticated attacker holding only the two view permissions of a control-servlet webapp (e.g. CATALOG_VIEW and OFBTOOLS_VIEW on /catalog, held by OFBiz's own shipped order-entry clerk role) to execute arbitrary operating system commands as the OFBiz service account with a single GET request, by placing an apostrophe followed by FreeMarker expression source in a screen link parameter value, because renderLink concatenates link parameter values verbatim between apostrophes into an unquoted, unescaped template-source string that is compiled and evaluated at render time, allowing the injected expression to reach the allow-listed FlexibleStringExpander.expandString call and, through a runtime-assembled Groovy interpolation, unsandboxed code execution. Users are recommended to upgrade to version 24.09.08, which fixes this issue.
