Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Bugzilla is vulnerable to cross-site scripting, script injection, and |
| 19 |
request forgery. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Bugzilla is a bug tracking system used to allow developers to more |
| 25 |
easily track outstanding bugs in products. |
| 26 |
|
| 27 |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
The vulnerabilities identified in Bugzilla are as follows: |
| 39 |
|
| 40 |
* Frederic Buclin and Gervase Markham discovered that input passed to |
| 41 |
various fields throughout Bugzilla were not properly sanitized before |
| 42 |
being sent back to users (CVE-2006-5453). |
| 43 |
|
| 44 |
* Frederic Buclin and Josh "timeless" Soref discovered a bug when |
| 45 |
viewing attachments in diff mode that allows users not of the |
| 46 |
"insidergroup" to read attachment descriptions. Additionally, it was |
| 47 |
discovered that the "deadline" field is visible to users who do not |
| 48 |
belong to the "timetrackinggroup" when bugs are exported to XML |
| 49 |
(CVE-2006-5454). |
| 50 |
|
| 51 |
* Gavin Shelley reported that Bugzilla allows certain operations to |
| 52 |
be performed via HTTP GET and HTTP POST requests without verifying |
| 53 |
those requests properly (CVE-2006-5455). |
| 54 |
|
| 55 |
* Max Kanat-Alexander discovered that input passed to |
| 56 |
showdependencygraph.cgi is not properly sanitized before being |
| 57 |
returned to users (CVE-2006-5453). |
| 58 |
|
| 59 |
Impact |
| 60 |
====== |
| 61 |
|
| 62 |
An attacker could inject scripts into the content loaded by a user's |
| 63 |
browser in order to have those scripts executed in a user's browser in |
| 64 |
the context of the site currently being viewed. This could include |
| 65 |
gaining access to privileged session information for the site being |
| 66 |
viewed. Additionally, a user could forge an HTTP request in order to |
| 67 |
create, modify, or delete bugs within a Bugzilla instance. Lastly, an |
| 68 |
unauthorized user could view sensitive information about bugs or bug |
| 69 |
attachments. |
| 70 |
|
| 71 |
Workaround |
| 72 |
========== |
| 73 |
|
| 74 |
There is no known workaround at this time. |
| 75 |
|
| 76 |
Resolution |
| 77 |
========== |
| 78 |
|
| 79 |
All Bugzilla users should upgrade to the latest version: |
| 80 |
|
| 81 |
# emerge --sync |
| 82 |
# emerge --ask --oneshot --verbose ">=www-apps/bugzilla-2.18.6" |
| 83 |
