CVE-2024-34070: Froxlor Vulnerable to Blind XSS Leading to Froxlor Application Compromise

Noroxi assessment

Priority: Monitor (action score 38/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.97% (FIRST EPSS); higher than 62% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: froxlor Froxlor 2.1.9.

Low priority for now. Upgrade to froxlor Froxlor 2.1.9 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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.
