ISS X-Force Database: php-phpinfo-long-array-xss(25702): PHP phpinfo() long array cross-site scripting

PHP phpinfo() long array cross-site scripting

php-phpinfo-long-array-xss (25702)

Medium Risk

Description:

PHP is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the php_print_gpcse_array() function. A remote attacker could exploit this vulnerability on affected PHP-based Web applications using an array value larger than 4096 bytes to execute script in a victim's Web browser within the security context of the hosting Web site, allowing the attacker to steal the victim's cookie-based authentication credentials.
