<title>Ruby: CGI::Session creates files insecurely</title>
|
|
<synopsis>
|
|
When used for CGI scripting, Ruby creates session files in /tmp with the
|
|
permissions of the default umask. Depending on that umask, local users may
|
|
be able to read sensitive data stored in session files.

Ruby is an Object Oriented, interpreted scripting language used for many
|
|
system scripting tasks. It can also be used for CGI web applications.

The CGI::Session::FileStore implementation (and presumably
|
|
CGI::Session::PStore), which allow data associated with a particular
|
|
Session instance to be written to a file, writes to a file in /tmp with no
|
|
regard for secure permissions. As a result, the file is left with whatever
|
|
the default umask permissions are, which commonly would allow other local
|
|
users to read the data from that session file.

|

|
|
Depending on the default umask, any data stored using these methods could
|
|
be read by other users on the system.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
By changing the default umask on the system to not permit read access to
|
|
other users (e.g. 0700), one can prevent these files from being readable by
|
|
other users.
|
|

All Ruby users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge sync
|
|
|
|
# emerge -pv ">=dev-lang/ruby-your_version"
|
|
# emerge ">=dev-lang/ruby-your_version"</code>
