"The remote web server contains a PHP application that is affected by
multiple vulnerabilities.");
  script_set_attribute(attribute:"description", value:
"According to its banner, the remote host is running a version of phpBB
that suffers from multiple flaws:

  - A Path Disclosure Vulnerability
    A remote attacker can cause phpBB to reveal its installation
    path via a direct request to the script 'db/oracle.php'.

  - A Cross-Site Scripting Vulnerability
    The application does not properly sanitize user input before
    using it in 'privmsg.php' and 'viewtopic.php'.

  - A Privilege Escalation Vulnerability
    In 'session.php' phpBB resets the 'user_id' value when an 
    autologin fails; it does not, however, reset the 'user_level' 
    value, which remains as the account that failed the autologin.
    Since the software uses the 'user_level' parameter in some 
    cases to control access to privileged functionality, this flaw
    allows an attacker to view information, and possibly even 
    perform tasks, normally limited to administrators. 

  - SQL Injection Vulnerabilities
    The DLMan Pro and LinksLinks Pro mods, if installed, reportedly 
    fail to properly sanitize user input to the 'file_id' parameter
    of the 'dlman.php' script and the 'id' parameter of the
    'links.php' script respectively before using it in a SQL 
    query. This may allow an attacker to pass malicious input
    to database queries.");
