Bugzilla LDAP Injection / Directory Browsing

Change Mirror Download
Summary
=======

Bugzilla is a Web-based bug-tracking system used by a large number of
software projects. The following security issues have been discovered
in Bugzilla:

* When the user logs in using LDAP, the username is not escaped
before being passed to LDAP which could potentially lead to LDAP
injection.

* Extensions are not protected against directory browsing by default
and users can view the source code of templates used by the
extensions. These templates may contain sensitive data.

All affected installations are encouraged to upgrade as soon as
possible.


Vulnerability Details
=====================

Class: LDAP Injection
Versions: 2.12 to 3.6.10, 3.7.1 to 4.0.7, 4.1.1 to 4.2.2,
4.3.1 to 4.3.2
Fixed In: 3.6.11, 4.0.8, 4.2.3, 4.3.3
Description: When the user logs in using LDAP, the username is not
escaped when building the uid=$username filter which is
used to query the LDAP directory. This could potentially
lead to LDAP injection.

CVE Number: CVE-2012-3981

Class: Directory Browsing
Versions: 2.23.2 to 3.6.10, 3.7.1 to 4.0.7, 4.1.1 to 4.2.2,
4.3.1 to 4.3.2
Fixed In: 4.0.8, 4.2.3, 4.3.3
Description: Extensions are not protected against directory browsing
and users can access the source code of the templates
which may contain sensitive data.
Directory browsing is blocked in Bugzilla 4.3.3 only,
because it requires a configuration change in the Apache
httpd.conf file to allow local .htaccess files to use
Options -Indexes. To not break existing installations,
this fix has not been backported to stable branches.
The access to templates is blocked for all supported
branches except the old 3.6 branch, because this branch
doesn't have .htaccess in the bzr repository and cannot
be fixed easily for existing installations without
potentially conflicting with custom changes.
