DESCRIPTION:
Some vulnerabilities have been reported in the vBShout module for
vBulletin, which can be exploited by malicious users to conduct
script insertion attacks and by malicious people to conduct
cross-site scripting attacks.

1) Input passed to the "message" parameter in vbshout.php (when "do"
is set to "archive" and "instanceid" is valid) is not properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and script code in a user's browser session in
context of an affected site.

This vulnerability is reported in versions prior to 6.0.4.

2) Input passed via the "reportreason" and "modnotes" parameters in
Shout Reports is not properly sanitised before being used. This can
be exploited to insert arbitrary HTML and script code, which will be
executed in a user's browser session in context of an affected site
if malicious data is viewed.

This vulnerability is reported in versions prior to 6.0.6.

SOLUTION:
Update to version 6.0.6.

PROVIDED AND/OR DISCOVERED BY:
1) Avram Marius Gabriel.
2) Reported by the vendor.
