GLSA-200801-11 : CherryPy: Directory traversal vulnerability

high Nessus Plugin ID 30116

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200801-11 (CherryPy: Directory traversal vulnerability)

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.
Impact :

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.
Workaround :

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

Solution

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'
