"The remote host is affected by the vulnerability described in GLSA-200411-32
(phpBB: Remote command execution)

    phpBB contains a vulnerability in the highlighting code and several
    vulnerabilities in the username handling code.
  
Impact :

    An attacker can exploit the highlighting vulnerability to access the
    PHP exec() function without restriction, allowing them to run arbitrary
    commands with the rights of the web server user (for example the apache
    user). Furthermore, the username handling vulnerability might be abused
    to execute SQL statements on the phpBB database."
