Jobberbase 2.0 – Multiple Vulnerabilities
Jobberbase: http://www.jobberbase.com/ Version: 2.0 By Ross Marks: http://www.rossmarks.co.uk 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="https://www.exploit-db.com/exploits/40351/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 ** notes ** admin change password page don't need old password, no csrf token just a simple POST request. admin password stored in md5 format unsalted cookies do NOT have "secure" or "HTTPonly" flags enabled no csrf anywhere |
