IMPACT:
Cross Site Scripting, Exposure of sensitive information

WHERE:

SOFTWARE:
eyeOS 0.x

DESCRIPTION:
Ryan McGeehan has discovered a vulnerability and a security issue in
eyeOS, which can be exploited by malicious users to conduct script
insertion attacks and by malicious people to disclose sensitive
information.

1) Input passed to the "motd" parameter in "desktop.php" in eyeBoard
isn't properly sanitised before being used. This can be exploited to
inject arbitrary HTML and script code, which will be executed in
another user's browser session in context of an affected site when
the malicious user data is viewed.

2) The problem is that user credentials are stored in the file
"usrinfo.xml" inside the web root. This can be exploited to disclose
usernames and encrypted passwords.

The vulnerability and the security issue have been confirmed in
version 0.8.4. Prior versions may also be affected.

SOLUTION:
Update to version 0.8.5.

NOTE: Security issue #2 has been fixed by adding a configuration
option for the location of user credentials. Please read the security
manual for more information.
