Mantisbt : Security Vulnerabilities, CVEs, (Gain Privilege)

CAPTCHA bypass vulnerability in MantisBT before 1.2.19.

MantisBT before 1.2.19 and 1.3.x before 1.3.0-beta.2 does not properly restrict access to /*/install.php, which allows remote attackers to obtain database credentials via the install parameter with the value 4.

bug_report.php in MantisBT before 1.2.18 allows remote attackers to assign arbitrary issues via the handler_id parameter.

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.

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.

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.
