An issue was discovered in PHPMailer before 5.2.22. PHPMailer's msgHTML method applies transformations to an HTML document to make it usable as an email message body. One of the transformations is to convert relative image URLs into attachments using a script-provided base directory. If no base directory is provided, it resolves to /, meaning that relative image URLs get treated as absolute local file paths and added as attachments. To form a remote vulnerability, the msgHTML method must be called, passed an unfiltered, user-supplied HTML document, and must not set a base directory. • https://www.exploit-db.com/exploits/43056 https://github.com/cscli/CVE-2017-5223 http://kalilinux.co/2017/01/12/phpmailer-cve-2017-5223-local-information-disclosure-vulnerability-analysis http://www.securityfocus.com/bid/95328 https://github.com/PHPMailer/PHPMailer/blob/master/SECURITY.md • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The isMail transport in PHPMailer before 5.2.20 might allow remote attackers to pass extra parameters to the mail command and consequently execute arbitrary code by leveraging improper interaction between the escapeshellarg function and internal escaping performed in the mail function in PHP. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-10033. El transporte isMail en PHPMailer en versiones anteriores a 5.2.20 podrían permitir a atacantes remotos pasar parámetros extra al comando de correo y consecuentemente ejecutar código arbitrario aprovechando una interacción inapropiada entre la función escapeshellarg y un escape interno realizado en la función mail en PHP. NOTA: esta vulnerabilidad existe debido a una incorrecta reparación de CVE-2016-10033. • https://www.exploit-db.com/exploits/42221 https://www.exploit-db.com/exploits/40969 https://www.exploit-db.com/exploits/40986 http://openwall.com/lists/oss-security/2016/12/28/1 http://packetstormsecurity.com/files/140286/PHPMailer-Remote-Code-Execution.html http://packetstormsecurity.com/files/140350/PHPMailer-Sendmail-Argument-Injection.html http://seclists.org/fulldisclosure/2016/Dec/81 http://www.rapid7.com/db/modules/exploit/multi/http/phpmailer_arg_injection http://www.securityfocus& • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') •

The mailSend function in the isMail transport in PHPMailer before 5.2.18 might allow remote attackers to pass extra parameters to the mail command and consequently execute arbitrary code via a \" (backslash double quote) in a crafted Sender property. La función mailSend en el transporte isMail en PHPMailer en versiones anteriores a 5.2.18 podrían permitir a atacantes remotos pasar parámetros extra al comando mail y consecuentemente ejecutar código arbitrario a través de una \" (barra invertida comillas dobles) en una propiedad Sender manipulada. PHPMailer version 5.2.17 suffers from a remote code execution vulnerability. • https://www.exploit-db.com/exploits/41962 https://www.exploit-db.com/exploits/42024 https://www.exploit-db.com/exploits/41996 https://www.exploit-db.com/exploits/40974 https://www.exploit-db.com/exploits/42221 https://www.exploit-db.com/exploits/40970 https://www.exploit-db.com/exploits/40968 https://www.exploit-db.com/exploits/40969 https://www.exploit-db.com/exploits/40986 https://github.com/opsxcq/exploit-CVE-2016-10033 https://github.com/GeneralTesler/CVE- • CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') •

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. • http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177130.html http://lists.fedoraproject.org/pipermail/package-announce/2016-February/177139.html http://www.debian.org/security/2015/dsa-3416 http://www.openwall.com/lists/oss-security/2015/12/04/5 http://www.openwall.com/lists/oss-security/2015/12/05/1 http://www.securityfocus.com/bid/78619 https://github.com/PHPMailer/PHPMailer/commit/6687a96a18b8f12148881e4ddde795ae477284b0 https://github.com/PHPMailer/PHPMailer/releases/tag& • CWE-20: Improper Input Validation •
