Absolute path traversal vulnerability in steps/mail/sendmail.inc in Roundcube Webmail before 0.7.3 and 0.8.x before 0.8.6 allows remote attackers to read arbitrary files via a full pathname in the _value parameter for the generic_message_footer setting in a save-perf action to index.php, as exploited in the wild in March 2013.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
