phpwcms 1.2.5-DEV and earlier, and 1.1 before RC4, allows remote attackers to execute arbitrary code via a crafted argument to the nome_evento parameter to phpwcms_code_snippets/mail_file_form.php and (2) sample_ext_php/mail_file_form.php, which is processed by the render_PHPcode function.

CRLF injection vulnerability in (1) include/inc_act/act_formmailer.php and possibly (2) sample_ext_php/mail_file_form.php in phpwcms 1.2.5-DEV and earlier, and 1.1 before RC4, allows remote attackers to modify HTTP headers and send spam e-mail via a spoofed HTTP Referer (HTTP_REFERER).
