What is CVE-2017-12061?
CVE-2017-12061 is a medium-severity cross-site scripting vulnerability in Mantisbt Mantisbt, published on 1 Aug 2017. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
An XSS issue was discovered in admin/install.php in MantisBT before 1.3.12 and 2.x before 2.5.2. Some variables under user control in the MantisBT installation script are not properly sanitized before being output, allowing remote attackers to inject arbitrary JavaScript code, as demonstrated by the $f_database, $f_db_username, and $f_admin_username variables. This is mitigated by the fact that the admin/ folder should be deleted after installation, and also prevented by CSP.
Weakness: CWE-79
