multiple SQL injection vulnerabilities :
   

  - Multiple SQL injection vulnerabilities exist due to
    improper sanitization of user-supplied input passed via
    the 'Username' field, the 'action' parameter, and the
    'polloptions' parameter. A remote attacker can exploit
    this issue to manipulate SQL queries, resulting in the
    disclosure of sensitive information and modification of
    data. (CVE-2005-2580)

  - A SQL injection vulnerabilities exists due to improper
    sanitization of user-supplied input passed via the 'uid'
    parameter. A remote attacker can exploit this issue to
    manipulate SQL queries, resulting in the disclosure of
    sensitive information and modification of data.
    (CVE-2005-2697)

  - A SQL injection vulnerabilities exists due to improper
    sanitization of user-supplied input passed via the 'fid'
    parameter in the member.php script. A remote attacker
    can exploit this issue to manipulate SQL queries,
    resulting in the disclosure of sensitive information and
    modification of data. (CVE-2005-2778)

Note that the application is reportedly affected by several additional
SQL injection vulnerabilities. However, Nessus has not
tested for the additional vulnerabilities.");
