CVE-2024-30879: Rageframe Reflected XSS Vulnerability

CVE-2024-30879 Overview

CVE-2024-30879 is a reflected Cross-Site Scripting (XSS) vulnerability in RageFrame2 version 2.6.43. The flaw resides in the image cropping function, where the boxId parameter accepts attacker-supplied input without proper sanitization. Remote attackers can craft a malicious URL that injects arbitrary HTML or JavaScript into the response. When a victim loads the crafted link, the injected script executes in the victim's browser session. The weakness is categorized as [CWE-79] Improper Neutralization of Input During Web Page Generation.

Critical Impact
Successful exploitation allows attackers to execute arbitrary scripts in the victim's browser, enabling session theft, credential harvesting, and sensitive information disclosure within the RageFrame2 administrative interface.

Affected Products

RageFrame2 version 2.6.43
Deployments exposing the image cropping functionality
Web applications built on the vulnerable RageFrame2 release

Technical Details for CVE-2024-30879

Vulnerability Analysis

The vulnerability is a reflected XSS flaw within RageFrame2's image cropping component. User-controlled data supplied through the boxId parameter is echoed back into the rendered HTML response without encoding or validation. An attacker crafts a URL containing a JavaScript payload inside boxId and delivers it to a target. When the victim loads the link while authenticated, the browser interprets the injected markup as part of the trusted application. The script executes under the origin of the RageFrame2 instance, inheriting the victim's session context and DOM access. Attackers can read cookies that lack the HttpOnly flag, exfiltrate CSRF tokens, perform actions on behalf of the user, and pivot into further administrative functions. Because the attack requires user interaction with a crafted link, delivery typically occurs through phishing, chat, or forum posts targeting authenticated administrators.

Root Cause

The root cause is missing output encoding on the boxId request parameter before it is reflected into the HTML response generated by the image cropping handler. RageFrame2 2.6.43 does not apply contextual escaping or input validation on this parameter, violating secure output handling practices for user-supplied data.

Attack Vector

Exploitation is network-based and requires user interaction. The attacker constructs a URL referencing the image cropping endpoint with a malicious payload in the boxId parameter. The victim must click or load the link while browsing the vulnerable RageFrame2 instance. No authentication is required to craft the URL, but a privileged victim session magnifies impact. Public technical details are tracked in the RageFrame2 GitHub Issue #114 Discussion.

Detection Methods for CVE-2024-30879

Indicators of Compromise

HTTP requests to RageFrame2 image cropping endpoints containing boxId parameter values with <script>, onerror=, javascript:, or URL-encoded equivalents
Web server access logs showing unusually long or encoded boxId query strings referred from external domains
Browser console errors or Content Security Policy violation reports originating from image cropping pages

Detection Strategies

Deploy a web application firewall (WAF) rule that inspects the boxId parameter for HTML tags and JavaScript event handlers
Enable server-side request logging that captures full query strings for the image cropping endpoint and alert on reflected payload patterns
Review referrer headers to identify victims clicking crafted links from untrusted sources

Monitoring Recommendations

Forward RageFrame2 web server and application logs to a centralized analytics platform for query-string anomaly detection
Monitor administrative accounts for session anomalies, including unexpected IP changes or concurrent sessions following link clicks
Alert on Content Security Policy violation reports that reference inline script execution on cropping pages

How to Mitigate CVE-2024-30879

Immediate Actions Required

Restrict access to the RageFrame2 administrative interface using IP allowlisting or VPN until a patched release is deployed
Instruct administrators and content editors to avoid clicking RageFrame2 links received from untrusted sources
Deploy WAF signatures that block script tags and event handlers in the boxId query parameter

Patch Information

No vendor patch is referenced in the current NVD record for RageFrame2 2.6.43. Monitor the RageFrame2 GitHub repository for upstream fixes and upgrade when a release addressing the reflected XSS flaw becomes available.

Workarounds

Apply a reverse-proxy filter that strips or encodes HTML metacharacters from the boxId parameter before requests reach RageFrame2
Enforce a strict Content Security Policy that disallows inline scripts and restricts script sources to trusted origins
Set HttpOnly and Secure flags on session cookies to limit the impact of successful script injection

bash

# Example NGINX rule to block script payloads in the boxId parameter
if ($args ~* "boxId=[^&]*(<|%3C)\s*script") {
    return 403;
}
