From remote

Impact:

Cross Site Scripting, Spoofing, Exposure of sensitive information

Solution Status:

Vendor Patch

CVE Reference(s):

Description


Multiple vulnerabilities have been reported in Bugzilla, which can be exploited by malicious, local users to gain access to potentially sensitive information and by malicious users to disclose potentially sensitive information, conduct script insertion and spoofing attacks.

1) Input passed via patch attachments is not properly sanitised before being viewed in "Raw Unified" mode. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when the malicious data is being viewed.

Successful exploitation of this vulnerability requires the victim to use Internet Explorer or Safari browsers.

2) Two errors when handling certain URLs during creation or editing of a bug and custom searches can be exploited to disclose the existence of a confidential group and its name.

3) An input sanitation error when processing attachment descriptions can be exploited to inject email headers when a flagmail notification is sent.

4) Insecure handling of temporary files for uploaded attachments can be exploited by local users to disclose the contents.

The vulnerabilities are reported in versions 3.4.11 and prior, 3.5.1 through 3.6.5, 3.7.1 through 4.0.1, and 4.1.1 through 4.1.2.


Solution:
Update to version 3.4.12, 3.6.6, or 4.1.3 (please see the vendor's advisory for details).
