Froxlor: Stored XSS in DNS TXT Record Content Allows Customer-to-Admin Account Takeover

CVSS 3.1

8.7High

Official description

Froxlor is open source server administration software. Prior to 2.3.8, DNS TXT record content accepted by lib/Froxlor/Api/Commands/DomainZones.php can contain HTML special characters, lib/Froxlor/UI/Callbacks/Text.php returns the content from Text::wordwrap without HTML escaping, and templates/Froxlor/table/table.html.twig renders the callback result with the raw filter. An authenticated customer with DNS editor access can store JavaScript-bearing content in a TXT record. When an administrator views the affected domain's DNS configuration, the payload executes automatically in the administrator's browser session, which can expose session data or perform privileged panel actions. This issue is fixed in version 2.3.8.
