CVE-2024-50677: Oroinc OroPlatform CMS XSS Vulnerability

CVE-2024-50677 Overview

CVE-2024-50677 is a reflected cross-site scripting (XSS) vulnerability in OroPlatform CMS v5.1. The flaw resides in the Search parameter, which fails to sanitize user-supplied input before rendering it in the response. Attackers can craft malicious payloads that execute arbitrary JavaScript or HTML in the victim's browser session. The vulnerability is tracked under CWE-79 (Improper Neutralization of Input During Web Page Generation).

Successful exploitation requires user interaction, typically by tricking a victim into clicking a crafted link. The scope change indicates that an attacker can affect resources beyond the vulnerable component.

Critical Impact
Attackers can execute arbitrary scripts in the browser context of authenticated OroPlatform users, enabling session hijacking, credential theft, and phishing against back-office operators.

Affected Products

OroPlatform CMS version 5.1.0
OroCommerce deployments built on the affected oroinc/oroplatform component
Any downstream application embedding the vulnerable Search functionality

Technical Details for CVE-2024-50677

Vulnerability Analysis

The vulnerability is a reflected XSS flaw affecting the Search parameter in OroPlatform CMS v5.1. When a user submits a search request, the application echoes the parameter value into the rendered HTML response without adequate output encoding or contextual sanitization. An attacker can supply a payload containing HTML or JavaScript that the browser then parses and executes.

Because the attack vector is network-based and requires no privileges, any unauthenticated attacker can craft an exploit URL. The user interaction requirement means the victim must visit the malicious link, typically delivered through phishing, forum posts, or third-party sites. The changed scope reflects that scripts executing in the OroPlatform origin can pivot to other trusted resources loaded by the browser.

Root Cause

The root cause is improper neutralization of input during web page generation, classified as CWE-79. The Search parameter handler in OroPlatform CMS v5.1 concatenates or renders the raw request value into HTML output. The framework does not apply HTML entity encoding or a context-aware templating escape to the parameter before it reaches the DOM.

Attack Vector

An attacker constructs a URL targeting the OroPlatform search endpoint with a JavaScript payload injected into the Search query parameter. The attacker distributes the URL through phishing email, chat, or malicious webpages. When an authenticated administrator or customer opens the link, the browser executes the payload under the OroPlatform origin. The script can then read session cookies not marked HttpOnly, exfiltrate CSRF tokens, submit authenticated requests, or rewrite the DOM to mount a credential phishing overlay.

A public proof of concept is available in the GitHub PoC for CVE-2024-50677 repository. Refer to the PoC and the OroCommerce Application Repository for technical details of the vulnerable code path.

Detection Methods for CVE-2024-50677

Indicators of Compromise

HTTP requests to OroPlatform search endpoints containing <script>, onerror=, onload=, javascript:, or encoded variants in the Search query parameter
Web server access logs showing unusually long or URL-encoded values in the search parameter originating from external referrers
Outbound requests from user browsers to attacker-controlled domains immediately following visits to OroPlatform search URLs
Unexpected session or cookie access patterns from OroPlatform back-office user accounts

Detection Strategies

Deploy Web Application Firewall (WAF) rules that inspect the Search parameter for HTML tags, event handlers, and JavaScript URI schemes
Enable Content Security Policy (CSP) reporting to capture inline script violations attempted through the OroPlatform origin
Correlate reverse-proxy logs with browser telemetry to identify reflected payloads returned in HTTP responses

Monitoring Recommendations

Alert on OroPlatform HTTP 200 responses that contain reflected content matching known XSS payload signatures
Monitor authenticated administrator sessions for anomalous API calls initiated shortly after search interactions
Track referrers landing on /search endpoints from untrusted external domains and flag high-volume campaigns

How to Mitigate CVE-2024-50677

Immediate Actions Required

Inventory all OroPlatform and OroCommerce deployments and identify instances running version 5.1.0
Apply vendor-supplied patches or upgrade to a fixed release once available from oroinc
Restrict access to the OroPlatform back office through IP allowlisting or VPN while remediation is in progress
Rotate administrator session credentials and review recent audit logs for signs of session abuse

Patch Information

At the time of publication, no vendor advisory URL is listed in the NVD entry for CVE-2024-50677. Administrators should monitor the OroCommerce Application Repository and official oroinc release notes for a security update addressing the Search parameter sanitization issue.

Workarounds

Deploy WAF rules that block or sanitize requests containing HTML tags and JavaScript event handlers in the search parameter
Enforce a strict Content Security Policy that disallows inline scripts and restricts script sources to trusted origins
Set the HttpOnly and Secure flags on session cookies to reduce the impact of script execution in the browser
Educate operators and customers to avoid clicking untrusted links pointing to the OroPlatform search endpoint

bash

# Example NGINX rule to block obvious XSS payloads in the search parameter
if ($arg_search ~* "(<script|onerror=|onload=|javascript:)") {
    return 403;
}
