statics-server Cross-site Scripting vulnerability
An XSS in statics-server <= 0.0.9 can be used via injected iframe in the filename when statics-server displays directory index in the browser. Statics-server does not implement any HTML escaping when displays directory index in the browser. Variable v is used in <a href> element without escaping, which allows to embed HTML <iframe> tag with src attribute points to another HTML file in the directory. This file can contain malicious JavaScript code, which will be executed:
// ./node_modules/statics-server/index.js, line 18:
if(fs.lstatSync(staticPath).isDirectory()){
var files=fs.readdirSync(staticPath);
var lis='';
files.forEach((v,i)=>{
if(fs.lstatSync(path.resolve(staticPath,v)).isDirectory()){
lis+=`<li><a href="${req.url}${v}/">${v}/</a></li>`;
}else {
lis+=`<li><a href="${req.url}${v}">${v}</a></li>`
}
});
