Description:
Some vulnerabilities have been reported in Bugzilla, which can be exploited by malicious people or malicious users to disclose potentially sensitive information, conduct cross-site scripting, script insertion, and request forgery attacks.
1) Input passed to various fields and when embedded in <h1> and <h2> tags is not properly sanitised before being returned to users. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
2) An error when viewing attachments in "diff" mode allows users, who are not members of "insidergroup", to read the descriptions of all attachments. Additionally, when exporting bugs to the XML format, the "deadline" field is also visible for users, who are not member of the "timetrackinggroup" group. This can be exploited to gain knowledge of potentially sensitive information.
3) Bugzilla allows users to perform certain sensitive actions via HTTP GET and POST requests without verifying the user's request properly. This can be exploited to e.g. modify, delete, or create user accounts, parameters, or products.
4) Input passed to showdependencygraph.cgi is not properly sanitised before being returned to users. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Solution:
Update to version 2.18.6, 2.20.3, 2.22.1, or 2.23.3.
NOTE: Vulnerability #3 is fixed in versions 2.22.1 and 2.23.3 only.
