Cross-site scripting (XSS) vulnerability in the projax_array_serialize_for_autocomplete function in core/projax_api.php in MantisBT 1.1.0a3 through 1.2.17 allows remote attackers to inject arbitrary web script or HTML via the "profile/Platform" field.

The print_test_result function in admin/upgrade_unattended.php in MantisBT 1.1.0a3 through 1.2.x before 1.2.18 allows remote attackers to obtain database credentials via a URL in the hostname parameter and reading the parameters in the response sent to the URL.

SQL injection vulnerability in the mc_project_get_attachments function in api/soap/mc_project_api.php in MantisBT before 1.2.18 allows remote attackers to execute arbitrary SQL commands via the project_id parameter. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-1609.

Cross-site scripting (XSS) vulnerability in account_sponsor_page.php in MantisBT 1.0.0 through 1.2.15 allows remote authenticated users to inject arbitrary web script or HTML via a project name.

core/email_api.php in MantisBT before 1.2.12 does not properly manage the sending of e-mail notifications about restricted bugs, which might allow remote authenticated users to obtain sensitive information by adding a note to a bug before losing permission to view that bug.

MantisBT before 1.2.12 does not use an expected default value during decisions about whether a user may modify the status of a bug, which allows remote authenticated users to bypass intended access restrictions and make status changes by leveraging a blank value for a per-status setting.

MantisBT before 1.2.9 does not audit when users copy or clone a bug report, which makes it easier for remote attackers to copy bug reports without detection.

The SOAP API in MantisBT before 1.2.9 does not properly enforce the bugnote_allow_user_edit_delete and delete_bug_threshold permissions, which allows remote authenticated users with read and write SOAP API privileges to delete arbitrary bug reports and bug notes.

The mci_check_login function in api/soap/mc_api.php in the SOAP API in MantisBT before 1.2.9 allows remote attackers to bypass authentication via a null password.

MantisBT before 1.2.9 does not properly check permissions, which allows remote authenticated users with manager privileges to (1) modify or (2) delete global categories.
