The mci_account_get_array_by_id function in api/soap/mc_account_api.php in MantisBT before 1.2.18 allows remote attackers to obtain sensitive information via a (1) mc_project_get_users, (2) mc_issue_get, (3) mc_filter_get_issues, or (4) mc_project_get_issues SOAP request.

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.
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.
MantisBT before 1.2.18 uses the public_key parameter value as the key to the CAPTCHA answer, which allows remote attackers to bypass the CAPTCHA protection mechanism by leveraging knowledge of a CAPTCHA answer for a public_key parameter value, as demonstrated by E4652 for the public_key value 0.
