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.
gpc_api.php in MantisBT 1.2.17 and earlier allows remote attackers to bypass authenticated via a password starting will a null byte, which triggers an unauthenticated bind.
