DESCRIPTION:
Gjoko Krstic has discovered a weakness and multiple vulnerabilities
in phlyMail Lite, which can be exploited by malicious users to
conduct script insertion attacks and by malicious people to conduct
spoofing attacks.

1) Input passed via the "go" parameter to frontend/derefer.php is not
properly verified before being used to redirect users. This can be
exploited to redirect a user to an arbitrary website e.g. when a user
clicks a specially crafted link to the affected script hosted on a
trusted domain.

2) Input passed via the "name" and "url" POST parameters to
config.php (when "screen" and "module" is set to "bookmarks") 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.

Successful exploitation of this vulnerability requires administrative
access.

3) Input passed via multiple POST parameters to config.php (when
"action" is set to "users" and "whattodo" is set to "savenewuser") 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.

List of affected scripts and parameters:
http://[host]/config.php?PHM[cellular]&PHM[customer_number]&PHM[email]
http://[host]/config.php?PHM[externalemail]&PHM[fax]&PHM[firstname]&PHM[www]
http://[host]/config.php?PHM[lastname]&PHM[tel_business]&PHM[tel_private]

Successful exploitation of this vulnerability requires administrative
access and "Write" permissions to the "User management" module.

The weakness and vulnerabilities are confirmed in phlyMail Lite
4.03.04. Other versions may also be affected.

SOLUTION:
No official solution is currently available.

PROVIDED AND/OR DISCOVERED BY:
