Adobe Connect Input Validation Flaws Let Remote Users Conduct Clickjacking and Cross-Site Scripting Attacks
Severity Rating: High
Systems Affected:
  • Adobe Connect versions 9.6.1 and before
Description
Several vulnerabilities were reported in Adobe Connect and can be exploited by remote attackers to conduct click-jacking attacks and cross-site scripting attacks. The vulnerabilities reported are as follows:
 
·         A vulnerability exists that can allow a remote user to hijack a target user's mouse clicks to take actions on the site acting as the target user.
 
·         A vulnerability exists because the software does not properly filter HTML code from user-supplied input before displaying the input. A remote user can cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Adobe Connect software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
