Technical Details & Description:
================================
A persistant email spoofing web vulnerability has been discovered in the official Trendmirco online-service web-application.
The vulnerability allows an remote attacker to send spoofed emails with injected malicious script codes or changed content.
The persistent vulnerability is located in the `Share your protection` email function. It allows users to promote a product to friends or family.
Remote attackers are able to inject own malicious script codes to the `download url` & `message` values of the `sendEmail` POST method request.
The request method to inject is POST and the attack vector of the vulnerability is located on the application-side of the service. Remote attackers
are able to manipulate the download url source and the message body context. The execution occurs in the email that arrives to the target inbox,
when preparing to share.
The security risk of the application-side web vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 4.6.
Exploitation of the application-side web vulnerability requires a low privileged web-application user account and low or medium user interaction.
Successful exploitation of the vulnerability results in persistent phishing mails, session hijacking, persistent external redirect to malicious
sources and application-side manipulation of affected or connected software module context.
