Notability date July 2009 Email injection is a security vulnerability that can occur in Internet application software applications that are used to send email messages. It is the email equivalent of HTTP Header Injection . Like SQL injection attacks, this vulnerability is one of a general class of vulnerabilities that occur when one programming language is embedded within another. When a form is added to a World Wide Web Web page that submits data to a Web application, a malicious user may exploit the MIME format to append additional information to the message being sent, such as a new list of recipients or a completely different message body. Because the MIME format uses a carriage return to delimit the information in a message, and only the raw message determines its eventual destination, adding carriage returns to submitted form data can allow a simple guestbook to be used to send thousands of messages at once. A malicious spam electronic spammer could use this tactic to send large numbers of messages anonymously. More information on this topic, including examples and ways to avoid the vulnerability, can be found at the http www.damonkohler.com 2008 12 email injection.html SecurePHP Wiki .

An injection port is a medical device used for the administration of insulin or other physician approved medicine into the subcutaneous tissue the tissue layer just below the skin . The device is similar to Infusion set infusion sets used by Insulin pump insulin pumps , except it is configured to receive a syringe instead of a tubing system. An injection port is usually a disposable device applied by the patient and worn for period of 3 5 days. When giving shots via an injection port, the needle stays above the surface of the skin. Medication is delivered via a short, soft cannula . An injection port can be used in conjunction with multiple daily injections of insulin by people with diabetes. It can also be used for the subcutaneous administration of any other physician prescribed medication Applying, Wearing and Using Injection ports are usually applied by the patient. The device comes with a needle surrounded by a soft cannula . The needle and cannula are manually inserted into the patient s tissue. Immediately after insertion the needle is removed and the cannula remains below the surface of the skin. Ports are usually worn on the abdomen, but can also be worn on other areas such as the buttocks, thigh or arm. Typical injection ports are worn for 3 5 days and then replaced with another port. Insulin is injected via a syringe into the injection port. Medication immediately flows through the device s cannula into the subcutaneous tissue layer.
