2) Input passed to the "prenumber" and "nextnumber" parameters in "news.php" is not properly verified before being used in a loop statement. This can be exploited to consume a large amount of CPU and memory resources on a vulnerable system.
3) Input passed to the username and password in the administration login is not properly sanitised before being used in a SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.
It is also possible to disclose the full path to "usercheck.php" by accessing it with invalid input.
The vulnerabilities have been reported in version 0.0.4. Other versions may also be affected.
Solution: Edit the source code to ensure that input is properly sanitised and verified.
