According to its self-reported version number, the detected Joomla! application is affected by multiple vulnerabilities :
A flaw exists in the JFilterInput::isFileSafe() function due to improper validation of file types and extensions of uploaded files before placing them in a user-accessible path. An unauthenticated, remote attacker can exploit this issue, by uploading a specially crafted file using an alternative PHP extension and then requesting it, to execute arbitrary code with the privileges of the web service. Note that this issue affects versions 3.0.0 to 3.6.4. (CVE-2016-9836)
An information disclosure vulnerability exists in the Beez3 com_content article layout override due to inadequate access control list (ACL) checks. An authenticated, remote attacker can exploit this to disclose restricted content. Note that this issue affects versions 3.0.0 to 3.6.4. (CVE-2016-9837)
A privilege escalation vulnerability exists due to improper validation of form data before storing it in the session. An authenticated, remote attacker can exploit this, via a specially crafted request, to modify existing user accounts, such as resetting credentials or group assignments. (CVE-2016-9838)
Note that the scanner has not tested for these issues but has instead relied only on the application’s self-reported version number.
