eval

gistfile1.txt

The line that raises a red flag for "Code Injection" vulnerability is:

javascript
Copy code
return eval(c.substring(token.length, c.length));
The use of eval() is dangerous, especially when it is working with data that can be manipulated by an attacker, such as cookie values. In this case, an attacker can set a malicious cookie named "pluto" which, when processed by the getWindowIdList() function, will execute arbitrary code via the eval() function.

To fix this, you should remove the eval() function and parse the cookie value in a safe manner. Assuming that the value after "pluto=" in the cookie is a JSON array, you can use JSON.parse() to safely convert the string to an array:

javascript
Copy code
function getWindowIdList() {
    var token = "pluto=";

    var ca = document.cookie.split(';');

    for(var i=0; i<ca.length; i++) {
        var c = eatSpacesFromFront(ca[i]);

        if (c.indexOf(token) != -1) {
            try {
                return JSON.parse(c.substring(token.length, c.length));
            } catch (e) {
                console.error("Error parsing pluto cookie:", e);
            }
        }
    }

    return [];
}
By using JSON.parse(), you safely convert the cookie value to an array without risking code execution. Always remember to avoid eval() wherever possible due to its inherent security risks.
