CVE-2025-23460: RWS Enquiry Plugin XSS Vulnerability

CVE-2025-23460 Overview

CVE-2025-23460 is a Reflected Cross-Site Scripting (XSS) vulnerability affecting the RWS Enquiry And Lead Follow-up WordPress plugin developed by rhizomaticweb. This vulnerability allows attackers to inject malicious scripts into web pages viewed by users, potentially leading to session hijacking, credential theft, or malware distribution through legitimate WordPress installations.

The vulnerability stems from improper neutralization of user-supplied input during web page generation, a classic CWE-79 weakness. When exploited, an attacker can craft malicious URLs that, when clicked by authenticated users, execute arbitrary JavaScript code in the context of the victim's browser session.

Critical Impact
Attackers can execute arbitrary JavaScript in victims' browsers, potentially stealing session cookies, performing actions on behalf of authenticated users, or redirecting users to malicious websites.

Affected Products

RWS Enquiry And Lead Follow-up WordPress plugin version 1.0 and earlier
WordPress sites running the rws-enquiry plugin

Technical Details for CVE-2025-23460

Vulnerability Analysis

This Reflected XSS vulnerability exists in the RWS Enquiry And Lead Follow-up plugin for WordPress. The plugin fails to properly sanitize and encode user-supplied input before reflecting it back in HTTP responses. This allows attackers to inject malicious script content that executes in the context of a victim's browser when they visit a specially crafted URL.

Reflected XSS attacks typically require social engineering to trick users into clicking malicious links. In the context of WordPress plugins like rws-enquiry, this could target site administrators who have elevated privileges, making the potential impact significant.

Root Cause

The root cause of this vulnerability is the failure to implement proper input validation and output encoding for user-controlled parameters. The plugin processes user input and includes it directly in the rendered HTML response without applying appropriate sanitization functions such as esc_html(), esc_attr(), or wp_kses() that WordPress provides for preventing XSS attacks.

This represents a violation of secure coding practices where all untrusted input should be treated as potentially malicious and properly escaped before being rendered in HTML contexts.

Attack Vector

The attack vector involves crafting a malicious URL containing JavaScript payload in one or more vulnerable parameters. The attacker then distributes this URL through phishing emails, social media, or other channels. When a victim clicks the link while authenticated to the WordPress site, the injected script executes with the victim's session privileges.

A typical attack scenario might involve:

Attacker identifies a vulnerable parameter in the plugin's request handling
Attacker constructs a URL with embedded JavaScript payload
Victim is tricked into clicking the malicious link
The plugin reflects the malicious input in the response without sanitization
Victim's browser executes the attacker's JavaScript code

Detection Methods for CVE-2025-23460

Indicators of Compromise

Unusual JavaScript code in URL parameters targeting the rws-enquiry plugin endpoints
User reports of unexpected browser behavior or redirects when accessing plugin pages
Web server logs containing encoded script tags or JavaScript event handlers in query strings
Anomalous outbound connections from client browsers after visiting plugin pages

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block common XSS payload patterns
Configure Content Security Policy (CSP) headers to prevent inline script execution
Monitor web server access logs for suspicious URL patterns containing script tags or encoded payloads
Deploy browser-based XSS protection mechanisms and audit their effectiveness

Monitoring Recommendations

Enable detailed logging for all WordPress plugin activity and HTTP requests
Set up alerts for URLs containing potential XSS payloads targeting the rws-enquiry plugin
Regularly review browser console errors that may indicate blocked XSS attempts
Monitor for unusual user session behavior that could indicate session hijacking

How to Mitigate CVE-2025-23460

Immediate Actions Required

Disable or remove the RWS Enquiry And Lead Follow-up plugin (rws-enquiry) until a patched version is available
Implement a Web Application Firewall (WAF) with XSS filtering rules
Configure strict Content Security Policy (CSP) headers to mitigate XSS impact
Educate administrators about phishing risks and suspicious URLs

Patch Information

At the time of publication, no patch information is available from the vendor. Organizations using the RWS Enquiry And Lead Follow-up plugin should consider removing the plugin or implementing compensating controls until a security update is released. Monitor the Patchstack WordPress Vulnerability Report for updates on available patches.

Workarounds

Deactivate and delete the rws-enquiry plugin from WordPress installations if not essential
Deploy a WAF rule to filter requests containing script tags or JavaScript event handlers
Implement restrictive CSP headers to prevent inline script execution
Limit administrator access to trusted networks only

bash

# Add CSP header in Apache .htaccess as a mitigation measure
Header set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none';"

# Or in nginx configuration
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none';";
