TITLE:
Bugzilla Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA18979

VERIFY ADVISORY:
http://secunia.com/advisories/18979/

CRITICAL:
Moderately critical

IMPACT:
Cross Site Scripting, Manipulation of data, Exposure of sensitive
information

WHERE:
>From remote

SOFTWARE:
Bugzilla 2.x
http://secunia.com/product/396/

DESCRIPTION:
Some vulnerabilities have been reported in Bugzilla, which can be
exploited by malicious users to conduct SQL injection attacks, and by
malicious people to disclose sensitive information and conduct script
insertion attacks.

1) Input passed to the "whinedays" parameter in "editparams.cgi"
isn't properly sanitised before being used in a SQL query. This can
be exploited to manipulate SQL queries by injecting arbitrary SQL
code.

Successful exploitation requires administrative privileges.

The vulnerability has been reported in versions prior to  2.20.1 and
2.22rc1 (from version 2.17.1).

2) The problem is that some RSS readers decodes encoded HTML in feed
titles. This can be exploited to inject arbitrary HTML and script
code, which will be executed in a user's RSS readers session in
context of an affected site when the malicious user data is viewed.

The vulnerability has been reported in versions 2.20rc1 through 2.20
and 2.21.1.

3) The problem is that users may send login requests to an incorrect
web site when the URL contains a double slash in the path name.

Successful exploitation requires that the login page is a
subdirectory of the web root and that the subdirectory is a
resolvable address on the user's network.

The vulnerability has been reported in versions prior to  2.20.1 and
2.22rc1 (from version 2.19.3).

SOLUTION:
Update to version 2.18.5 or 2.20.1.
