CVE-2025-11067: Visitor Management System XSS Vulnerability

CVE-2025-11067 Overview

CVE-2025-11067 is a reflected cross-site scripting (XSS) vulnerability in Projectworlds Visitor Management System 1.0. The flaw resides in the Add Visitor Page component, specifically in the /myform.php script. Attackers can inject malicious script payloads through the Name parameter, which the application renders back to users without proper sanitization or output encoding.

The issue is classified under [CWE-79] (Improper Neutralization of Input During Web Page Generation). Remote exploitation is possible over the network, though it requires high privileges and user interaction. The exploit has been publicly disclosed, raising the likelihood of opportunistic abuse against exposed deployments.

Critical Impact
Successful exploitation enables execution of attacker-controlled JavaScript in the browser context of an authenticated visitor management user, enabling session theft, credential capture, or unauthorized actions.

Affected Products

Technical Details for CVE-2025-11067

Vulnerability Analysis

The Projectworlds Visitor Management System accepts visitor registration data through the /myform.php endpoint. The Name field submitted through the Add Visitor form is processed and rendered without sufficient input validation or contextual output encoding. An attacker submitting a crafted payload containing HTML or JavaScript can trigger script execution when the value is reflected in the application interface.

Because the application handles visitor records viewed by administrative users, the injected payload runs within the browser session of a privileged operator. This exposes session cookies, authentication tokens, and any actions the user is authorized to perform through the management console.

Root Cause

The root cause is missing neutralization of special characters in user-supplied input before it is embedded in HTML output. The application fails to apply either input sanitization at the server boundary or context-aware output encoding when rendering the Name field. This aligns with the [CWE-79] weakness pattern for reflected XSS.

Attack Vector

Exploitation requires network access to the application and an authenticated session with permission to submit visitor entries. The attacker submits a payload through the Name parameter of /myform.php. The stored or reflected value executes when a user renders the affected view. User interaction is required to trigger the payload, which limits the practical severity but does not eliminate risk in shared administrative environments.

The vulnerability mechanism is documented in the public GitHub Issue Tracker and the VulDB entry #326106. No verified proof-of-concept code is republished here.

Detection Methods for CVE-2025-11067

Indicators of Compromise

HTTP POST requests to /myform.php containing <script>, onerror=, onload=, or encoded variants in the Name parameter
Web server access logs showing unusual URL-encoded characters (%3C, %3E, %22) submitted to the Add Visitor form
Outbound requests from administrator browsers to unfamiliar domains shortly after loading visitor records

Detection Strategies

Deploy a web application firewall (WAF) rule set that inspects Name form fields for HTML tag patterns and JavaScript event handlers
Enable server-side logging of all POST parameters submitted to /myform.php and alert on payloads matching XSS signatures
Perform authenticated dynamic application security testing (DAST) against the Add Visitor workflow to confirm exposure

Monitoring Recommendations

Monitor administrator sessions for anomalous cookie access patterns or unexpected DOM modifications
Correlate visitor record submissions with subsequent administrator activity to identify potential payload triggers
Track outbound network connections from browser processes on workstations used to manage the application

How to Mitigate CVE-2025-11067

Immediate Actions Required

Restrict network exposure of the Visitor Management System to trusted internal networks only
Audit user accounts with access to the Add Visitor page and remove unnecessary privileges
Review historical visitor records for previously submitted payloads and purge malicious entries
Implement a WAF rule blocking HTML and JavaScript patterns in the Name parameter until a patched build is available

Patch Information

No vendor patch has been published in the referenced advisories at the time of writing. Consult the VulDB submission #659652 and the upstream Projectworlds repository for updated releases. Organizations dependent on this application should evaluate migration to an actively maintained alternative.

Workarounds

Apply server-side input validation that rejects or encodes <, >, ", ', and & characters in the Name field
Add a Content Security Policy (CSP) header that disallows inline script execution to reduce payload viability
Set the HttpOnly and Secure flags on session cookies to limit script-based theft
Require administrators to use isolated browser profiles when accessing the application

bash

# Example nginx configuration to add a restrictive Content Security Policy
add_header Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self';" always;
add_header X-XSS-Protection "1; mode=block" always;
add_header X-Content-Type-Options "nosniff" always;
