4. *Vulnerability Description*



SQL injection is a code injection technique that exploits a security

vulnerability occurring in the database layer of an application. The

vulnerability is present when user input is either incorrectly filtered for

string literal escape characters embedded in SQL statements or user input

is not strongly typed and thereby unexpectedly executed.



For additional information, please look at the references [1] and [2].

7. *Credits*



This vulnerability was discovered by Ryan Dewhurst ( ryan -at- bonsai-sec.com ).





8. *Technical Description*



A SQL injection vulnerability was found in the dispatch.php script, more

specifically in the $user_id variable. The vulnerability can be triggered by

logging into Achievo and browsing to:



/dispatch.php?atknodetype=reports.weekreport&atkaction=report&nameswitch=name&userid=%27&functionlevelswitch=all&startdate[day]=6&startdate[month]=7&startdate[year]=2009&enddate[day]=17&enddate[month]=7&enddate[year]=2009&showstatus=all&outputType=0&atkorderby=period



Which will generate a syntax error in the database. The following is

the corresponding piece of code:



classweekreport.inc:128-134

function get_employee($user_id)

{

    $db = &atkGetDb();

    $sql = "SELECT * FROM person WHERE status='active' AND id='$user_id'";

    $record = $db->getrows($sql);

    return $record[0];

}
