Status:

Published

Exploitation-Technique:

Remote

Severity:

High

Details:

A HTML Inject & a File Include vulnerabilit is detected on TreasonSMS IPhone application. The vulnerability allows an
remote attacker to include malicious persistent script codes on application-side of the iphone. This possible way allows the

jailbreaked the vulnerability exploitation can also result full controll of the affected IPhone. The Bug is located in the
input fields of the Message Sending & Message Output. An attacker can scan the victim on walkthrough because the ip
