Overview |
The "Email-Template" module has no file type validation and a remote
attacker could lead the admin
to create a especially crafted malicious email template that allows the
remote attacker to compromise
the entire system.

WorkAround |
The Admin has the capabilities to create and a "Email-Template" that would
be stored in the directory:
Since the module doesn't have any file type validation the admin can upload
any arbitrary file type,
so a remote attacker can gain access by just leading the (already logged-in)
admin to and a specially
crafted (malicious) website that truth a Cross-site Request Forgery make the
admin automatically create
a email template.
This could lead to a remote attacker to gain access and further more
compromise the entire system.

Proof Of Concept|
ChX Security will not release any proof of concept.

By the moment there is no official solution provided by the vendor(s)...
