CVE Descriptions

Safe Mode feature (safe_mode) in PHP 3.0 through 4.1.0 allows attackers with access to the MySQL database to bypass Safe Mode access restrictions and read arbitrary files using "LOAD DATA INFILE LOCAL" SQL statements.

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.

<?php /* source: https://www.securityfocus.com/bid/4026/info PHP's 'safe_mode' feature may be used to restrict access to certain areas of a filesystem by PHP scripts. However, a problem has been discovered that may allow an attacker to bypass these restrictions to gain unauthorized access to areas of the filesystem that are restricted when PHP 'safe_mode' is enabled. In particular, the MySQL client library that ships with PHP fails to properly honor 'safe_mode'.
