Js sandbox causing errors

[Blatzar]

Describe the bug

9e254cc seems to have caused issues with eval_in_node()

Without modifications it gives NameError: name 'path' is not defined

Editing https://github.com/vn-ki/anime-downloader/blob/master/anime_downloader/util.py#L402 to os.path will result in error below

To reproduce

anime -ll DEBUG dl "hunter x hunter" --provider animekisa -c 2

Wow you still get different errors.. You don't seem to have the path one at all.

[Blatzar]

@LiteracyFanatic any ideas how to solve this?

[LiteracyFanatic]

Here's what I've got so far. Adding from os import path resolves the error you found. I'm not really sure why that's necessary; I'll have to do some reading. However, this still doesn't work properly because the value from the js is being returned incorrectly. Here's the raw js run through a formatter.

eval = console.log;
eval(
  (function (p, a, c, k, e, d) {
    while (c--)
      if (k[c])
        p = p.replace(new RegExp("\\b" + c.toString(a) + "\\b", "g"), k[c]);
    return p;
  })(
    'n.1q={1p:"",q:"c",1o:"3://r.2.1/i/1n/6.1m",1l:[{b:"3://r.2.1:1k/d/1j/c.p",q:"c/p",}],};9 o=m.1i("1h");o.1g=l(){n.1f();k.1e("3://8.2.1/6");1d 1c};$(m).1b(l(){1a($(k).a()<19){$("#5").4("b","3://j.2.1/18.7");$("#5").4("h","g");$("#5").4("a","17")}16{$("#5").4("b","3://j.2.1/15.7");$("#5").4("h","g");$("#5").4("a","14")}});9 13="3://8.2.1/6";9 f=\'<e 12="3://8.2.1/f-6.7" 11=0 10=0 z=0 y=x w=v u=t s></e>\';',
    36,
    63,
    "|com|mp4upload|https|attr|aa1fa793|x50ng81bqkhy|html|www|var|width|src|video||IFRAME|embed|260|height||cdn|window|function|document|player|dl|mp4|type|www6|allowfullscreen|360|HEIGHT|494|WIDTH|NO|SCROLLING|MARGINHEIGHT|MARGINWIDTH|FRAMEBORDER|SRC|link|620|2bb|else|310|1bb|670|if|ready|false|return|open|pause|onclick|download|getElementById|sgx36fq3z3b4quuo3owaezyqj5pyyuhzwv76gqblwefm4ky4kzzdvpy4|282|sources|jpg|01239|poster|title|source".split(

  )
);

Which can be rewritten like this:

let p = 'n.1q={1p:"",q:"c",1o:"3://r.2.1/i/1n/6.1m",1l:[{b:"3://r.2.1:1k/d/1j/c.p",q:"c/p",}],};9 o=m.1i("1h");o.1g=l(){n.1f();k.1e("3://8.2.1/6");1d 1c};$(m).1b(l(){1a($(k).a()<19){$("#5").4("b","3://j.2.1/18.7");$("#5").4("h","g");$("#5").4("a","17")}16{$("#5").4("b","3://j.2.1/15.7");$("#5").4("h","g");$("#5").4("a","14")}});9 13="3://8.2.1/6";9 f=\'<e 12="3://8.2.1/f-6.7" 11=0 10=0 z=0 y=x w=v u=t s></e>\';';
let a = 36;
let c = 63;
let k = "|com|mp4upload|https|attr|aa1fa793|x50ng81bqkhy|html|www|var|width|src|video||IFRAME|embed|260|height||cdn|window|function|document|player|dl|mp4|type|www6|allowfullscreen|360|HEIGHT|494|WIDTH|NO|SCROLLING|MARGINHEIGHT|MARGINWIDTH|FRAMEBORDER|SRC|link|620|2bb|else|310|1bb|670|if|ready|false|return|open|pause|onclick|download|getElementById|sgx36fq3z3b4quuo3owaezyqj5pyyuhzwv76gqblwefm4ky4kzzdvpy4|282|sources|jpg|01239|poster|title|source".split("|");

while (c--) {
    if (k[c]) {
        p = p.replace(new RegExp("\\b" + c.toString(a) + "\\b", "g"), k[c]);
    }
}

console.log(p);

And evaluates to this:

player.source = {
  title: "",
  type: "video",
  poster: "https://www6.mp4upload.com/i/01239/x50ng81bqkhy.jpg",
  sources: [

      type: "video/mp4",
    },
  ],
};
var dl = document.getElementById("download");
dl.onclick = function () {
  player.pause();
  window.open("https://www.mp4upload.com/x50ng81bqkhy");
  return false;
};
$(document).ready(function () {
  if ($(window).width() < 670) {
    $("#aa1fa793").attr("src", "https://cdn.mp4upload.com/1bb.html");
    $("#aa1fa793").attr("height", "260");
    $("#aa1fa793").attr("width", "310");
  } else {
    $("#aa1fa793").attr("src", "https://cdn.mp4upload.com/2bb.html");
    $("#aa1fa793").attr("height", "260");
    $("#aa1fa793").attr("width", "620");
  }
});
var link = "https://www.mp4upload.com/x50ng81bqkhy";
var embed =
  '<IFRAME SRC="https://www.mp4upload.com/embed-x50ng81bqkhy.html" FRAMEBORDER=0 MARGINWIDTH=0 MARGINHEIGHT=0 SCROLLING=NO WIDTH=494 HEIGHT=360 allowfullscreen></IFRAME>';

I believe there is an issue related to the use of console.log and eval that is keeping the actual value we want from being returned properly. I'll need to do a bit more digging to figure out for sure what's going on.

[LiteracyFanatic]

I've added a preliminary fix. There's more work to be done to make sure all the other sites work as well, but this should be usable as is if you need it now.
