Zope is vulnerable to a file inclusion vulnerability when exposing RestructuredText functionalities to untrusted users.

2.  Impact Information


Zope is an application server that can be used to build content management systems, intranets, portals or other custom applications.


Zope honors file inclusion directives in RestructuredText objects by default.


An attacker could exploit the vulnerability by sending malicious input that would be interpreted in a RestructuredText Zope object, potentially resulting in the execution of arbitrary Zope code with the rights of the Zope server.

3.  Resolution Information


There is no known workaround at this time.


All Zope users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose net-zope/zope
