Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2017-12419 impacting mantisbt mantisbt. Evaluated with CVSS Base Score of 4.9 (MEDIUM).

Original NVD Description

Source: NIST NVD
If, after successful installation of MantisBT through 2.5.2 on MySQL/MariaDB, the administrator does not remove the 'admin' directory (as recommended in the "Post-installation and upgrade tasks" section of the MantisBT Admin Guide), and the MySQL client has a local_infile setting enabled (in php.ini mysqli.allow_local_infile, or the MySQL client config file, depending on the PHP setup), an attacker may take advantage of MySQL's "connect file read" feature to remotely access files on the MantisBT server.
