Bugzilla is a Web-based bug-tracking system, used by a large number of
This advisory covers three security issues that have recently been
fixed in the Bugzilla code:
* Users without the "canconfirm" privilege could enter a bug as NEW
or ASSIGNED by using the XML-RPC interface.
* When viewing several bugs at once, there was a Cross-Site Scripting
* The inbound email interface allowed you to set the Reporter via the
text of the email, instead of just using the From header.
All affected installations are encouraged to upgrade as soon as
Class: Unauthorized Bug Change
Description: Users normally need the "canconfirm" privilege to put bugs
in the NEW or ASSIGNED state. However, users were being
allowed to create bugs in the NEW or ASSIGNED state if they
were creating the bug through the XML-RPC interface.
Class: Cross-Site Scripting
Versions: 2.17.2 and higher
Description: When using the "Format for Printing" view of a bug (or
the "Long Format" of a bug list, which is the same thing),
there was a cross-site scripting hole--arbitrary text
from a particular URL parameter could be injected into the
page without filtering.
Class: Account Impersonation (Minor)
Versions: 2.23.4 and higher
Description: By design, email_in.pl always believes the "From" header as
the user making changes or uses that as the reporter of the
bug. However, you could also specify the changer/reporter
in the body of the email and override the "From" header,
possibly bypassing some security checks set up by
administrators against the "From" header.
For most installations this is a minor or inconsequential
issue, as the documentation of email_in.pl already explains
that it does not do any user authentication (it just
believes the "From" header), so installations using it
should not have been expecting user account security
(though they may have had checks against the "From"
header--that is what makes this a security issue).
The fixes for the security bugs mentioned in this advisory are
included in the 3.0.4, 3.1.4, 2.22.4, and 2.20.6 releases. Upgrading
to these releases will protect installations from possible exploits of
