CherryPy: Directory traversal vulnerability CherryPy is vulnerable to a directory traversal that could allow attackers to read and write arbitrary files. cherrypy 2008-01-27 2008-01-27 204829 remote 2.2.1-r2 3.0.2-r1 3.0.2-r1

CherryPy is a Python-based, object-oriented web development framework.

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.

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.

Disable the "FileSession" functionality by using "PostgresqlSession" or "RamSession" session management in your CherryPy application.

All CherryPy 2.2 users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=dev-python/cherrypy-2.2.1-r2"

All CherryPy 3.0 users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=dev-python/cherrypy-3.0.2-r1" CVE-2008-0252 rbu rbu p-y
