Two Cross-Site Scripting vulnerabilities have been discovered in Alkacon's OpenCMS affecting version 16, which could allow a user with sufficient privileges to create and modify web pages through the admin panel, can execute malicious JavaScript code, after inserting code in the “title” field.
Fixes

Solution

The Cross-Site Scripting vulnerability through the “title” field has been fixed in version 17. However, the vendor has stated that the Cross-Site Scripting vulnerability through images in .svg format will not be fixed because filtering the JavaScript code of .svg files could bring unwanted effects.


Workaround

No workaround given by the vendor.
