Descriptions

Multiple CRLF injection vulnerabilities in PHPMailer before 5.2.14 allow attackers to inject arbitrary SMTP commands via CRLF sequences in an (1) email address to the validateAddress function in class.phpmailer.php or (2) SMTP command to the sendCommand function in class.smtp.php, a different vulnerability than CVE-2012-0796.

Múltiples vulnerabilidades de inyección CRLF en PHPMailer en versiones anteriores a 5.2.14 permite a atacantes inyectar comandos SMTP arbitrarios a través de secuencias CRLF en (1) una dirección de correo electrónico de la función validateAddress en class.phpmailer.php o (2) un comando SMTP de la función sendCommand en class.smtp.php, una vulnerabilidad diferente a CVE-2012-0796.

Takeshi Terada discovered a vulnerability in PHPMailer, a PHP library for email transfer, used by many CMSs. The library accepted email addresses and SMTP commands containing line breaks, which can be abused by an attacker to inject messages.
