Multiple vulnerabilities have been reported in BugTracker.NET, which can be exploited by malicious users to conduct SQL injection attacks and by malicious people to conduct cross-site scripting attacks.

1) Input passed to the "pcd" parameter in edit_bug.aspx, "bug_id" parameter in edit_comment.aspx, "default_name" parameter in edit_customfield.aspx, and "id" parameter in edit_user_permissions2.aspx is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

2) Input passed via the "qu_id" parameter to bugs.aspx, "row_id" parameter to delete_query.aspx, "us_id" and "new_project" parameters to edit_bug.aspx, and "bug_list" parameter to massedit.aspx is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

The vulnerabilities are reported in version 3.4.4. Other versions may also be affected.

Solution
Update to version 3.4.5.
