<p>
|
|
CherryPy does not sanitize the session id, provided as a cookie value,
|
|
in the FileSession._get_file_path() function before using it as part of
|
|
the file name.
|
|
</p>

<impact type="normal">
|
|
<p>
|
|
A remote attacker could exploit this vulnerability to read and possibly
|
|
write arbitrary files on the web server, or to hijack valid sessions,
|
|
by providing a specially crafted session id. This only affects
|
|
applications using file-based sessions.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Disable the "FileSession" functionality by using "PostgresqlSession" or
|
|
"RamSession" session management in your CherryPy application.
|
|
</p>
|
|
</workaround>

All CherryPy 2.2 users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-python/cherrypy-2.2.1-r2"</code>
|
|
<p>
|
|
All CherryPy 3.0 users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-python/cherrypy-3.0.2-r1"</code>
