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

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 1.0% , percentile 62: FIRST’s model estimates a 1.0% chance of exploitation activity in the next 30 days, higher than 62% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.
- Only applies if your dependency tree includes froxlor/froxlor (Composer (PHP)) < 2.1.9, fixed in 2.1.9 . Check your lockfile, including transitive dependencies.

## What it is

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.

## Affected packages

- Composer (PHP) `froxlor/froxlor` < 2.1.9 → fixed: 2.1.9

## Affected products (CVE record)

- froxlor Froxlor: < 2.1.9

## Severity

- GitHub_M CVSS 3.1: 9.7 `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.6 `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.97% probability of exploitation activity in the next 30 days; percentile 62.
