PostNuke 0.75/0.76 DL - 'viewdownload.php' SQL Injection
source: https://www.securityfocus.com/bid/14636/info
PostNuke is prone to an SQL injection vulnerability. This issue is due to a lack of sufficient sanitization of user-supplied input.
Successful exploitation could result in a compromise of the application, disclosure or modification of data, or may permit an attacker to exploit vulnerabilities in the underlying database implementation.
