Descriptions

sapi/cgi/cgi_main.c in PHP before 5.3.12 and 5.4.x before 5.4.2, when configured as a CGI script (aka php-cgi), does not properly handle query strings that lack an = (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.

sapi/cgi/cgi_main.c en PHP antes de v5.3.12 y v5.4.x antes de v5.4.2, cuando se configura como un script CGI (también conocido como php-cgi), no maneja correctamente las cadenas de consulta que carecen de un carácter = (signo igual), lo que permite a atacantes remotos ejecutar código arbitrario mediante la colocación de línea de comandos en la cadena de consulta, relacionado con el fallo de saltarse cierto php_getopt para el caso de la 'd'.
