Concrete5 is prone to a stored cross-site scripting (XSS) vulnerability.

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
The vulnerability exists because config/concrete.php allows uploads (by administrators) of SVG files that may contain HTML data with a SCRIPT element.

Successful exploitation would allow an authenticated attacker to store malicious code inside the application which is then being executed when browsing to an affected site.

Affected Versions:
Concrete5 through version 8.4.3.

Update to version 8.4.4 or later.
