Описание
Banks generates meaningful LLM prompts using a template language that makes sense. Prior to 2.4.2, banks uses jinja2.Environment() (unsandboxed) to render prompt templates. Applications that pass user-supplied strings as the template argument to Prompt() are vulnerable to Server-Side Template Injection (SSTI), which can lead to Remote Code Execution (RCE) on the host system. This vulnerability is fixed in 2.4.2.
A flaw was found in banks. This vulnerability, known as Server-Side Template Injection (SSTI), allows a remote attacker to achieve Remote Code Execution (RCE) on the host system. This occurs when applications using banks pass user-supplied strings directly as template arguments to the Prompt() function, which then renders these templates in an unsandboxed environment.
Отчет
This Important flaw in the banks library allows remote code execution through Server-Side Template Injection (SSTI). The vulnerability arises when applications using banks pass unsanitized, user-supplied strings directly as template arguments to the Prompt() function, which then renders these templates in an unsandboxed environment. Exploitation requires the application to pass user-controlled data into Prompt() template function, which is not a standard procedure - limiting the attack's overall complexity.
Меры по смягчению последствий
To mitigate this issue, applications utilizing the banks library should avoid passing user-controlled data into Prompt() sink. This prevents malicious input from being interpreted as template code, thereby reducing the risk of Server-Side Template Injection and subsequent remote code execution. Recommended to update to patched version.
