Readme

# CVE-2024-44623
In [SPX-GC](https://github.com/TuomoKu/SPX-GC) 1.3.0v and below versions, user-controlled input was passed in the exec function of the child_process module without any sanitization, leading to unauthenticated blind remote code execution.

## Vulnerability
In [/routes/routes-api.js](https://github.com/TuomoKu/SPX-GC/blob/65f284f4b9dad4e8c694dd9de0086238c4f7d2b9/routes/routes-api.js#L37-L39), user input received from file param and passed into exec function of child_process leads to unauthenticated blind RCE

## Blind RCE
Blind Remote Code Execution (RCE) in web applications occurs when an attacker can execute arbitrary code on a server without immediate feedback or direct knowledge of the results. This vulnerability often arises from improper user input handling and can be exploited through mechanisms like command execution.
