CVE-2024-3084 Overview
CVE-2024-3084 is a reflected cross-site scripting (XSS) vulnerability in PHPGurukul Emergency Ambulance Hiring Portal 1.0. The flaw resides in the Hire an Ambulance page, where unsanitized user input is rendered back to the browser. Attackers can inject malicious script payloads through the Patient Name, Relative Name, Relative Phone Number, City, State, or Message parameters. Exploitation requires user interaction, typically luring a victim into loading a crafted URL or submitting a manipulated form. The vulnerability has been publicly disclosed and assigned identifier VDB-258677 by VulDB.
Critical Impact
Successful exploitation allows attackers to execute arbitrary JavaScript in a victim's browser session, enabling session token theft, credential harvesting, and phishing pivots against portal users.

Technical Details for CVE-2024-3084
Vulnerability Analysis
The vulnerability is a stored/reflected cross-site scripting weakness classified under [CWE-79]. The Hire an Ambulance page accepts multiple user-controlled fields and echoes them back into HTML responses without proper output encoding. Any script payload submitted in the affected parameters is interpreted by the victim's browser in the origin context of the portal.
Because the flaw requires user interaction, an attacker typically delivers a weaponized link or a pre-filled form to a target. Once the victim submits or loads the crafted request, the injected JavaScript executes, granting the attacker access to Document Object Model (DOM) content, cookies not marked HttpOnly, and any authenticated actions the user can perform.
Root Cause
The root cause is missing input sanitization and output encoding on form parameters processed by the Hire an Ambulance page. The application concatenates raw request data into HTML output rather than encoding characters such as <, >, and ". Absence of a Content Security Policy (CSP) header amplifies the impact by allowing inline script execution.
Attack Vector
Exploitation occurs over the network without authentication but requires the victim to interact with attacker-controlled content. A remote attacker crafts a malicious URL or HTML form that submits JavaScript through one of the affected fields. When the portal renders the field back to the user, the payload executes with the privileges of the victim's session. Refer to the GitHub XSS Vulnerability Documentation and VulDB entry #258677 for reproduction details.
Detection Methods for CVE-2024-3084
Indicators of Compromise
- Web server access logs containing <script>, onerror=, javascript:, or URL-encoded equivalents (%3Cscript%3E) in POST bodies or query strings targeting the Hire an Ambulance endpoint.
- Unexpected outbound requests from user browsers to attacker-controlled domains shortly after visits to the ambulance portal.
- Session cookies from portal users appearing in external referer logs or threat intelligence feeds.
Detection Strategies
- Deploy a web application firewall (WAF) rule set that flags HTML and JavaScript metacharacters in the Patient Name, Relative Name, Relative Phone Number, City, State, and Message parameters.
- Instrument the portal with runtime application self-protection (RASP) or logging that captures raw request payloads for the affected form.
- Correlate authentication anomalies, such as session reuse from new IP addresses, with recent form submissions containing suspicious characters.
Monitoring Recommendations
- Enable browser-side reporting via a Content-Security-Policy-Report-Only header to identify script violations against the portal.
- Aggregate portal access logs into a central analytics platform and alert on anomalous parameter lengths or encoded scripts.
- Review referer headers and administrator sessions for signs of stolen tokens or hijacked accounts.
How to Mitigate CVE-2024-3084
Immediate Actions Required
- Restrict public access to the Hire an Ambulance form using network controls or authentication until a fix is applied.
- Apply server-side input validation that rejects HTML control characters in the affected parameters.
- Enforce output encoding using functions such as htmlspecialchars($input, ENT_QUOTES, 'UTF-8') wherever user-supplied data is rendered.
- Set HttpOnly, Secure, and SameSite=Strict attributes on session cookies to limit exploitation impact.
Patch Information
No vendor patch has been published for PHPGurukul Emergency Ambulance Hiring Portal 1.0 as of the last NVD update. Administrators should track the VulDB advisory #258677 and the public disclosure repository for remediation guidance, and consider retiring the application if updates remain unavailable.
Workarounds
- Deploy a WAF signature that blocks requests containing <, >, or JavaScript event handlers in the vulnerable parameters.
- Add a strict Content Security Policy such as Content-Security-Policy: default-src 'self'; script-src 'self' to block inline script execution.
- Sanitize existing database records that may contain injected markup before rendering historical form submissions.
# Example Apache configuration to enforce a restrictive Content Security Policy
Header always set Content-Security-Policy "default-src 'self'; script-src 'self'; object-src 'none'; base-uri 'self'; frame-ancestors 'none'"
Header always set X-Content-Type-Options "nosniff"
Header always set X-Frame-Options "DENY"
Header edit Set-Cookie ^(.*)$ $1;HttpOnly;Secure;SameSite=Strict
