1.缺陷描述
Multiple SQL Injection, Cross-Site Scripting (XSS) and Information
Disclosure vulnerabilities were identified within Concrete5 version
5.4.2.1
注意: Only a select few vulnerabilities are outlined in this
disclosure, many other vulnerabilities were discovered. Due to time
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.

lastResponse, (select count(timestamp) from btSurveyResults where
btSurveyResults.bID = btSurvey.bID and btSurveyResults.cID =
CollectionVersions.cID) as numberOfResponses ' .
