Description

When searching the file list using SFTP, an error occurs when the file name or directory name contains a backslash.

An error occurs when calling the javascript JSON.parse() function, and for this reason, the entire file list is not displayed in the Devices menu (Alt+Ctrl+Shift).

Temporarily removing the backslash from the file name or directory name is effective, but I think that special characters should be escaped.

Attach the tested file name and error location.

1. File name: test\123
2. Error location

 

// guacamole-common-js/src/main/webapp/modules/JSONReader.js
this.getJSON = function getJSON() {
        return JSON.parse(json);
};

 

Thanks.
