Description:
Some vulnerabilities have been reported in AvailScript Jobs Portal Script, which can be exploited by malicious users to conduct SQL injection attacks and compromise a vulnerable system.

1) Input passed to the "jid" parameter in applynow.php is not properly sanitised before being used in an SQL query. This can be exploited to manipulate SQL queries by injecting arbitrary SQL code.

2) A vulnerability is caused due to missing restrictions on what file types users are allowed to upload via the "Edit Image/Logo" functionality. This can be exploited to execute arbitrary PHP code.

Solution:
Filter malicious characters and character sequences using a web proxy.
Edit the source code to ensure that input is properly validated.
