1) Local path disclosure - change any variable to an array and in most cases it will tell you the local path where the application is installed
    eg. http://example.com/api/api.php?action=getJobs&type[]=0&category=0&count=5&random=1&days_behind=7&response=js
    returns: Array to string conversion in <b>/var/www/jobberbase/_lib/class.Job.php</b>
 
2) Open redirect - when submitting an application can change "Referer:" header to anything and will redirect there
 
3) reflect XSS in username - http://example.com/admin/
        eg. "><script>alert(1)</script>
    reflect XSS in search: http://example.com/search/|<img src="x" onError="alert(1)">/
 
4) persistant XSS on admin backend homepage
        create a job and give the URL:
        " onhover="alert(1)
    persistant XSS - admin add to category name (no protection)
 
5) unrestricted file upload
    upload CV accepts any filetype appends _ uniqueid() to filename
    eg. "file.php" becomes "file_<uniqueid>.php"
    uniquid in in insecure method for generating random sequences and is based on microtime
    if the server is using an older version of PHP a null byte can be used 
    ie. "test.php%00.php" would be uploaded as "test.php"
 
6) code execution race condition:
    if the admin has chosen to not store uploaded CV's 
    they are first moved from /tmp to the writable /upload directory before being unlinked
    this gives a brief window of opportunity for an attacker to run http://example.com/uploads/file.php before it is deleted
 
7) SQL injection in http://example.com/api/api.php?action=getJobs&type=0&category=0&count=5&random=1&days_behind=7&response=js
    days_behind parameter is vulnerable
