CVE-2012-2311

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.

sapi/cgi/cgi_main.c de PHP anteriores a 5.3.13 y 5.4.x anteriores a 5.4.3, si está configurado como un script CGI (php-cgi), no maneja apropiadamente cadenas de petición que contienen una secuencia %3D pero ningún = (signo igual). Lo que permite a atacantes remotos ejecutar código arbitrario colocando opciones de comandos en la cadena de petición. Relacionado con la falta de supresión de un determinado php_getopt para el caso 'd'. NOTA: esta vulnerabilidad se debe a una solución incompleta de CVE-2012-1823.
