Summary

A security flaw has been discovered in Tecnick TCExam up to 16.6.0. Affected is the function F_xml_export_users of the file admin/code/tce_xml_users.php of the component XML Export. Performing a manipulation results in cross site scripting. Remote exploitation of the attack is possible. There are still doubts about whether this vulnerability truly exists. Upgrading to version 16.6.1 is able to address this issue. The patch is named 899b5b2fa09edfe16043f07265e44fe2022b7f12. It is suggested to upgrade the affected component. When the vendor was informed about another security issue, he identified and fixed this flaw during analysis. He doubts the impact of this: "However, this is difficult to justify as security issue. It requires to be administrator to both create and consume the exploit. Administrators can do pretty much anything in the platform, so I don't see the point of this from a security perspective." This is reflected by the CVSS vector.
