Multiple vulnerabilities have been reported in Bugzilla, which can be exploited by malicious users to gain knowledge of sensitive information, or conduct cross-site scripting and SQL injection attacks.

1) Under certain circumstances, an error message disclosing the database password is returned when the SQL server is stopped, and the web server is still running.

This security issue affects versions 2.17.1 through 2.17.7.

2) A privileged user able to grant membership to some groups (usually administrators) can bypass the administrative controls and grant membership to groups other than the ones, which the user has privileges for.

This vulnerability affects versions 2.17.1 through 2.17.7.

3) When Bugzilla is configured to hide certain products from users, it is still possible to gain knowledge of the names of these products via the "duplicates.cgi" and "buglist.cgi" CGI scripts.

This issue affects all versions prior to 2.16.6 and 2.18rc1.

4) Input passed to several administration CGI scripts is not properly sanitised before being returned to users. This can be exploited to execute arbitrary HTML and script code in a administrative user's browser session in context of an affected site.

The following CGI scripts are vulnerable:
* editcomponents.cgi
* editgroups.cgi
* editmilestones.cgi
* editproducts.cgi
* editusers.cgi
* editversions.cgi

This vulnerability affects all versions prior to 2.16.6 and 2.18rc1.

5) When a user is prompted to login when attempting to view a chart, the user's login ID and password are included as part of the image URL. This may disclose the information in web server log files.

This security issue affects versions 2.17.5 through 2.17.7.

6) An input validation error in "editusers.cgi" can be exploited by a malicious, privileged user to manipulate SQL queries by injecting arbitrary SQL code into the "query" parameter.

Successful exploitation requires that the user has privileges to grant membership to any group (usually administrators).

This vulnerability affects all versions prior to 2.16.6 and 2.18rc1.

Solution
The vulnerabilities have been addressed in versions 2.16.6 and 2.18rc1.
