Description
A security flaw has been discovered in AstrBotDevs AstrBot up to 4.22.1. This affects the function create_template of the file astrbot/dashboard/routes/t2i.py of the component Dashboard API. The manipulation results in improper neutralization of special elements used in a template engine. The attack can be executed remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
A server-side template injection vulnerability has been identified in AstrBotDevs AstrBot, affecting versions through 4.22.1. The issue arises in the Dashboard API, specifically within the 'create_template' function of 'astrbot/dashboard/routes/t2i.py'. This vulnerability allows authenticated users to create and update text-to-image (T2I) templates without any content validation or sanitization. The injected templates, which can include malicious Jinja2 payloads, are sent to a remote rendering endpoint for processing. Exploitation of this vulnerability could lead to unauthorized code execution or information disclosure on the rendering server.
It is recommended to sanitize template content by removing or escaping Jinja2 expressions before storage. Using Jinja2's SandboxedEnvironment on the rendering server can prevent code execution. Additionally, implementing a template allowlist and validating template content before storage can help mitigate the vulnerability.
