The vulnerability is caused by the application improperly validating uploaded files via e.g. the image upload functionality of the CKEditor, which can be exploited to execute arbitrary PHP code by uploading a PHP file with e.g. an appended ".jpg" file extension. Successful exploitation requires that the web server is not configured to handle the mime-types for files with e.g. a ".jpg" or ".gif" extension. ====================================================================== 5) Solution Update to version 3.0.01. ====================================================================== 6) Time Table 04/08/2011 - Requested security contact. 04/08/2011 - Vendor provides security contact. 06/08/2011 - Vendor notified. 23/09/2011 - Vendor releases version 3.0. 01/10/2011 - Vendor notified of incomplete fixes and additional vulnerabilities. 24/11/2011 - Additional details provided to the vendor. 13/12/2011 - Requested status update. 29/12/2011 - Requested status update. 15/01/2012 - Vendor releases version 3.0.01. 20/04/2012 - Public disclosure. ====================================================================== 7) Credits Discovered by Secunia Research. ====================================================================== 8) References The Common Vulnerabilities and Exposures (CVE) project has not currently assigned a CVE identifier for the vulnerability. ====================================================================== 9) About Secunia Secunia offers vulnerability management solutions to corporate customers with verified and reliable vulnerability intelligence relevant to their specific system configuration: https://www.flexera.com/advisories/business_solutions/ Secunia also provides a publicly accessible and comprehensive advisory database as a service to the security community and private individuals, who are interested in or concerned about IT-security.advisories/ Secunia believes that it is important to support the community and to do active vulnerability research in order to aid improving the security and reliability of software in general: https://www.flexera.com/about-us/secunia-research/advisories/ Secunia regularly hires new skilled team members.
