DESCRIPTION:
Multiple vulnerabilities have been discovered in the Minishop plugin
for gpEasy CMS, which can be exploited by malicious users to conduct
script insertion attacks.

1) Input passed via the "cat" and "catdesc" parameters to
Admin_Minishop (when "cmd" is set to "addcat") 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 when the malicious
data is being viewed.

2) Input passed via the "item", "itemdesc", and "itemprice"
parameters to Admin_Minishop (when "cmd" is set to "additem") 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 when the malicious
data is being viewed.

Successful exploitation of the vulnerabilities requires the "Admin
Minishop" permission.

The vulnerabilities are confirmed in version 1.5. Other versions may
also be affected.

SOLUTION:
No official solution is currently available.

PROVIDED AND/OR DISCOVERED BY:
