CWE-1336
AllowedImproper Neutralization of Special Elements Used in a Template Engine
Abstraction: Base · Status: Incomplete
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.

Title
Quest Foglight for Databases renderTemplateString Server-Side Template Injection Remote Code Execution Vulnerability
Summary
Quest Foglight for Databases renderTemplateString Server-Side Template Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Quest Foglight for Databases. Authentication is required to exploit this vulnerability.
The specific flaw exists within the renderTemplateString method. The issue results from the lack of proper validation of a user-supplied string before processing it with the template engine. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-29889.

Title
Polyaxon through 2.16.4 Server-Side Template Injection via Unsandboxed Jinja2 Engine
Summary
Polyaxon through 2.16.4 renders operation specification fields with an unsandboxed Jinja2 environment during server-side run preparation, allowing authenticated users to execute arbitrary code. Attackers can submit runs with Jinja2 payloads in queue, namespace, conditions, presets, or dependencies fields to execute operating system commands in the scheduler process context, exposing database credentials and service tokens.

Title
Backstage: Improper input validation in TechDocs MkDocs configuration
Summary
Backstage is an open framework for building developer portals. Prior to 1.14.6 and from 1.15.0 until 1.15.4, the @backstage/plugin-techdocs-node package insufficiently validates mkdocs.yml supplied by an authenticated user who can register or modify a TechDocs source. Unsafe Python YAML tags, markdown_extensions names and configuration, theme options, and extra_templates values can reach the documentation generator and cause unintended code execution. The resulting impact is limited to the files, credentials, network access, and other resources available to the TechDocs backend or build container. This issue is fixed in versions 1.14.6 and 1.15.4.

Title
Apache OFBiz: Authenticated Code Execution Vulnerability
Summary
Improper Neutralization of Special Elements Used in a Template Engine ('Server-Side Template Injection') in Apache OFBiz 24.09 before 24.09.08 on all platforms allows a remote authenticated attacker holding only a stock non-administrative account to execute arbitrary operating system commands as the OFBiz process user, by using the updateLayoutImage event, which writes DataResource fields with no permission check, to retype an attacker-created DataResource as an FTL template evaluating its own primary key, then using the resulting FreeMarker evaluation to plant an OFBiz Form Widget whose use-when attribute runs unsandboxed Groovy. Users are recommended to upgrade to version 24.09.08, which fixes this issue.

Title
Zammad: AI Agent template sanitizer bypass leads to remote code execution
Summary
Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, a security filter that protects Zammad's AI Agent configuration can be bypassed by entering specially crafted text into one of an AI Agent's fields. An administrator with permission to create or edit AI Agents could exploit this to run arbitrary commands on the server that hosts Zammad, potentially reading, modifying, or destroying all data stored on that server. No interaction from other users is needed; the malicious code runs automatically the next time the affected AI Agent processes a ticket. This issue is fixed in version 7.1.2.

Summary
In Eclipse Ditto versions [1.3.0, 3.9.6], the ImplicitThingCreationMessageMapper of the connectivity service builds a CreateThing command by substituting placeholder values (e.g. {{ header:device_id }}) resolved from inbound message headers into a pre-configured JSON "thing" template as raw, un-escaped strings, and then parses the resulting string as JSON. Because the placeholder engine performs no JSON escaping and is unaware of the surrounding JSON string context, a resolved value containing a double-quote character can break out of its string and inject additional JSON structure.
When a connection is configured to use this mapper with a template that reflects a header whose value a publishing device can control (for example an MQTT 5 user property, an AMQP 1.0 application property, or a Kafka record header), an attacker able to publish on that connection can inject an inline _policy object. The inline policy overrides the administrator-configured policyId, letting the attacker assign an arbitrary access-control policy to the newly created digital twin — gaining full read/write access to it and potentially revoking the legitimate owner's access, with no administrator interaction.
Exploitation requires all of the following: the connection uses the (non-default) ImplicitThingCreation mapper; its template reflects an attacker-controllable header; and, for the policy-override impact, the connection's authorization subjects are permitted to create policies (the default). Deployments that restrict the connection's subjects to thing creation only via the entity-creation configuration are not affected by the policy-override impact.

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.
