Description:
Several vulnerabilities were reported in Joomla!. A remote user can obtain potentially sensitive information on the target system. A remote user can conduct cross-site scripting attacks.
A remote user can exploit a cache access control flaw to view potentially sensitive information from forms on the target system [CVE-2017-9933]. Versions 1.7.3 and after are affected.
The software does not properly filter HTML code and validate CSRF tokens from user-supplied input before displaying the input [CVE-2017-9934]. 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 Joomla! 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. Versions 1.7.3 and after are affected.
The software does not properly filter multibyte characters in HTML code from user-supplied input before displaying the input [CVE-2017-7985]. 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 Joomla! 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. Versions 1.5.0 through 3.6.5 are affected.
