Descriptions

sapi/cgi/cgi_main.c in PHP before 5.3.13 and 5.4.x before 5.4.3, when configured as a CGI script (aka php-cgi), does not properly handle query strings that contain a %3D sequence but no = (equals sign) character, which allows remote attackers to execute arbitrary code by placing command-line options in the query string, related to lack of skipping a certain php_getopt for the 'd' case. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-1823.

CWE-ID Nom de la faiblesse Source
CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

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.

/* Apache Magica by Kingcope */ /* gcc apache-magika.c -o apache-magika -lssl */ /* This is a code execution bug in the combination of Apache and PHP. On Debian and Ubuntu the vulnerability is present in the default install of the php5-cgi package. When the php5-cgi package is installed on Debian and Ubuntu or php-cgi is installed manually the php-cgi binary is accessible under /cgi-bin/php5 and /cgi-bin/php. The vulnerability makes it possible to execute the binary because this binary has a security check enabled when installed with Apache http server and this security check is circumvented by the exploit. When accessing the php-cgi binary the security check will block the request and will not execute the binary. In the source code file sapi/cgi/cgi_main.c of PHP we can see that the security check is done when the php.ini configuration setting cgi.force_redirect is set and the php.ini configuration setting cgi.redirect_status_env is set to no. This makes it possible to execute the binary bypassing the Security check by setting these two php.ini settings. Prior to this code for the Security check getopt is called and it is possible to set cgi.force_redirect to zero and cgi.redirect_status_env to zero using the -d switch. If both values are set to zero and the request is sent to the server php-cgi gets fully executed and we can use the payload in the POST data field to execute arbitrary php and therefore we can execute programs on the system. apache-magika.c is an exploit that does exactly the prior described. It does support SSL. /* Affected and tested versions PHP 5.3.10 PHP 5.3.8-1 PHP 5.3.6-13 PHP 5.3.3 PHP 5.2.17 PHP 5.2.11 PHP 5.2.6-3 PHP 5.2.6+lenny16 with Suhosin-Patch Affected versions PHP prior to 5.3.12 PHP prior to 5.4.2 Unaffected versions PHP 4 - getopt parser unexploitable PHP 5.3.12 and up PHP 5.4.2 and up Unaffected versions are patched by CVE-2012-1823. */ /* . /'\rrq rk . // \\ . .x.//fco\\-|- '//cmtco\\zt //6meqrg.\\tq //_________\\' EJPGQO apache-magica.c by Kingcope */ #include <stdio.h> #include <stdlib.h> #include <unistd.h> #include <getopt.h> #include <sys/types.h> #include <stddef.h> #include <openssl/rand.h> #include <openssl/ssl.h> #include <openssl/err.h> #include <netdb.h> #include <sys/socket.h> #include <netinet/in.h> typedef struct { int sockfd;
