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 remote web server is hosting MantisBT, an open source bug tracking application written in PHP.

Versions of MantisBT prior to 1.2.18 are affected by the following vulnerabilities :

  - Multiple input validation errors exist that could allow cross-site scripting attacks. (CVE-2014-7146, CVE-2014-9271,  CVE-2014-9280, CVE-2014-9281)

  - An unspecified errors exist that could allow SQL injection attacks. (CVE-2014-9089)

  - Two unspecified errors exist that could allow information disclosure attacks. (CVE-2014-8553, CVE-2014-8988)

  - An error exists in the file 'gpc_api.php' that could allow an attacker to bypass authentication protections by using a password that starts with a NULL byte.(CVE-2014-6387)

  - An error exists in the 'XML Import/Export' plugin that could allow unauthorized attackers to upload XML files or obtain sensitive information. (CVE-2014-8598)

  - An error exists related to the CAPTCHA protection mechanism and the parameter 'public_key' that could allow security bypasses. (CVE-2014-9117)

According to its version number, the MantisBT application hosted on the remote web server is 1.2.x prior to 1.2.18. It is, therefore, affected by the following vulnerabilities :

  - Multiple input-validation errors exist that could allow     cross-site scripting attacks. (CVE-2014-7146,     CVE-2014-8986, CVE-2014-8987, CVE-2014-9269,     CVE-2014-9270, CVE-2014-9271, CVE-2014-9272,     CVE-2014-9280, CVE-2014-9281)

  - Two unspecified errors exist that could allow SQL     injection attacks. (CVE-2014-8554, CVE-2014-9089)

  - Three unspecified errors exist that could allow     information disclosure attacks. (CVE-2014-8553,     CVE-2014-8988, CVE-2014-9279)

  - An error exists in the file 'core/string_api.php' that     could allow open redirect attacks. (CVE-2014-6316)

  - An error exists in the file 'gpc_api.php' that could     allow an attacker to bypass authentication protections     by using a password that starts with a NULL byte.
    (CVE-2014-6387)

  - An error exists in the 'XML Import/Export' plugin that     could allow unauthorized attackers to upload XML files     or obtain sensitive information. (CVE-2014-8598)

  - An error exists related to the CAPTCHA protection     mechanism and the parameter 'public_key' that could     allow security bypasses. (CVE-2014-9117)

Note that Nessus has not attempted to exploit this issue but has instead relied only on the application's self-reported version number.

Multiple security issues have been found in the Mantis bug tracking system, which may result in phishing, information disclosure, CAPTCHA bypass, SQL injection, cross-site scripting or the execution of arbitrary PHP code.
