Some vulnerabilities have been reported in Hot Links SQL, which can be exploited by malicious people to disclose sensitive information or conduct cross-site scripting and SQL injection attacks.

1) A vulnerability is caused due to the scripts "dlback.php" (PHP version) and "dlback.cgi" (CGI version) respectively can be accessed without proper authentication. This can be exploited to download the latest created database backup.

Example:
http://[host]/dlback.php?dl=fullback

2) Input passed to the "id" parameter in report.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

3) Input passed to the "id" parameter in report.php is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

4) Input passed to the "id" parameter in report.cgi is not properly sanitised before being used in SQL queries. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

Vulnerabilities #2 and #3 are reported in the PHP version of Hot Links SQL. Vulnerability #4 is reported in the CGI version of Hot Links SQL.
