Weakness (CWE)
CWE-1336: Improper Neutralization of Special Elements Used in a Template Engine
The product uses a template engine to insert or process externally-influenced input, but it does not neutralize or incorrectly neutralizes special elements or syntax that can be interpreted as template expressions or other code directives when processed by the engine.
More detail
In some cases, XSS-style attacks can work, which can obscure the root cause if the developer does not closely investigate the root cause of the error.
Template engines can be used on the server or client, so both "sides" could be affected by injection. The mechanisms of attack or the affected technologies might be different, but the mistake is fundamentally the same.
How to prevent it (2 mitigations)
-
Architecture and Design
Choose a template engine that offers a sandbox or restricted mode, or at least limits the power of any available expressions, function calls, or commands.
-
Implementation
Use the template engine's sandbox or restricted mode, if available.
