What is CVE-2024-34070?
CVE-2024-34070 is a critical cross-site scripting vulnerability in Froxlor, published on 10 May 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
Froxlor is open source server administration software. Prior to 2.1.9, a Stored Blind Cross-Site Scripting (XSS) vulnerability was identified in the Failed Login Attempts Logging Feature of the Froxlor Application. An unauthenticated User can inject malicious scripts in the loginname parameter on the Login attempt, which will then be executed when viewed by the Administrator in the System Logs. By exploiting this vulnerability, the attacker can perform various malicious actions such as forcing the Administrator to execute actions without their knowledge or consent. For instance, the attacker can force the Administrator to add a new administrator controlled by the attacker, thereby giving the attacker full control over the application. This vulnerability is fixed in 2.1.9.
