CVE-2024-43244: Houzez Theme Reflected XSS Vulnerability

CVE-2024-43244 Overview

CVE-2024-43244 is a reflected Cross-Site Scripting (XSS) vulnerability in the Houzez WordPress theme developed by favethemes. The flaw stems from improper neutralization of user-supplied input during web page generation [CWE-79]. All versions of Houzez up to and including 3.2.4 are affected.

An attacker can craft a malicious URL containing JavaScript payloads. When a victim clicks the link, the script executes in the victim's browser session under the context of the vulnerable site. The vulnerability requires user interaction and operates over the network without authentication.

Critical Impact
Successful exploitation allows attackers to execute arbitrary JavaScript in a victim's browser, enabling session hijacking, credential theft, and content manipulation on real estate websites running the Houzez theme.

Affected Products

favethemes Houzez WordPress theme versions up to and including 3.2.4
WordPress sites using the Houzez real estate theme distributed via ThemeForest
Installations that have not applied the vendor patch released after version 3.2.4

Technical Details for CVE-2024-43244

Vulnerability Analysis

The vulnerability is a reflected XSS issue tracked under [CWE-79], Improper Neutralization of Input During Web Page Generation. The Houzez theme accepts user-supplied parameters and reflects them into HTTP responses without applying proper output encoding or input sanitization.

Reflected XSS issues differ from stored XSS because the malicious payload is delivered through a crafted request rather than persisted in the database. The attacker must convince a victim to interact with the malicious link. Because Houzez is widely deployed for real estate listing sites, the population of potential victims includes property buyers, agents, and site administrators.

The scope is marked as changed in the CVSS vector, indicating the impact extends beyond the vulnerable component to other browser security contexts. Confidentiality, integrity, and availability impacts are each rated low.

Root Cause

The root cause is missing or insufficient sanitization of HTTP request parameters before they are written into the rendered HTML response. User-controlled input flows from the request directly into the DOM, allowing HTML and JavaScript syntax to break out of the intended data context.

Attack Vector

Exploitation is performed over the network and requires user interaction. An attacker constructs a URL with a payload embedded in a vulnerable parameter, then delivers it via phishing email, social media, or a malicious referrer. When the victim loads the URL, the server reflects the payload into the response and the browser executes the injected script.

Detection Methods for CVE-2024-43244

Indicators of Compromise

HTTP requests to Houzez theme endpoints containing URL-encoded <script>, onerror=, onload=, or javascript: tokens in query parameters
Unusual outbound requests from user browsers to attacker-controlled domains shortly after visiting Houzez-powered sites
Web server access logs showing reflected parameter values containing HTML entities or angle brackets
Browser console errors or content security policy violations originating from Houzez theme pages

Detection Strategies

Inspect WordPress access logs for query strings containing script tags, event handlers, or encoded JavaScript payloads targeting Houzez routes
Deploy a web application firewall ruleset that flags reflected parameter content matching XSS signatures
Monitor referrer headers for suspicious links pointing to Houzez endpoints with long, encoded query strings
Correlate user-reported phishing emails with subsequent traffic to Houzez-powered domains

Monitoring Recommendations

Enable verbose HTTP request logging on the WordPress front-end and retain logs for at least 90 days
Track failed Content Security Policy (CSP) violations reported by browsers via report-uri endpoints
Alert on anomalous spikes in 200 responses to parameterized Houzez URLs containing non-printable characters
Review WordPress user session activity for unexpected administrator actions following the visit timestamp of a suspicious URL

How to Mitigate CVE-2024-43244

Immediate Actions Required

Update the Houzez theme to a version released after 3.2.4 that contains the vendor's official patch
Audit WordPress administrator and editor accounts for unauthorized changes if Houzez has been exposed to untrusted traffic
Rotate session cookies and require password resets for privileged users on affected sites
Notify site users about phishing risk and advise caution with unsolicited links to the property site

Patch Information

favethemes has released a fixed version addressing the reflected XSS issue. Site administrators must update the Houzez theme through the official vendor channel or the ThemeForest update mechanism. Consult the Patchstack Vulnerability Report for the fixed version number and release notes.

Workarounds

Deploy a web application firewall with XSS signature rules in front of the WordPress site until the patch can be applied
Implement a strict Content Security Policy that disallows inline scripts and restricts script sources to trusted origins
Set the HttpOnly and SameSite=Strict flags on session cookies to reduce session theft risk
Temporarily disable affected Houzez features or restrict access to the vulnerable endpoints via server configuration

bash

# Example Content Security Policy header for nginx
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; frame-ancestors 'self'; base-uri 'self';";
add_header X-Content-Type-Options "nosniff";
add_header X-Frame-Options "SAMEORIGIN";
