DESCRIPTION:
SmOk3 has reported a vulnerability in e107, which can be exploited to

script code can be included in "login name/author", which will be
executed in a user's browser session in context of a vulnerable site
when a malicious article or news posting is viewed.

Successful exploitation requires that the malicious person is logged
in as a guest user.
