CVE-2024-0314: FireEye Central Management XSS Vulnerability

CVE-2024-0314 Overview

CVE-2024-0314 is a reflected cross-site scripting (XSS) vulnerability in FireEye Central Management version 9.1.1.956704. An attacker can inject and modify special HTML elements in the application, causing the browser to render attacker-controlled script in the context of an authenticated administrator. Successful exploitation can lead to session hijacking of Central Management users. The issue is classified under [CWE-79] (Improper Neutralization of Input During Web Page Generation) and requires the target user to interact with a crafted link. Exploitation occurs over the network and does not require prior authentication from the attacker.

Critical Impact
A crafted URL delivered to an authenticated Central Management operator can execute script in the victim's session and enable session hijacking of the security management console.

Technical Details for CVE-2024-0314

Vulnerability Analysis

The vulnerability is a reflected XSS flaw in the web interface of FireEye Central Management. User-supplied input is reflected back into an HTTP response without adequate output encoding. An attacker can craft a URL containing HTML or JavaScript payloads that the application renders inside its own DOM. When an authenticated Central Management operator clicks the link, the injected script executes with the privileges of that session.

Because Central Management aggregates configuration and events for multiple FireEye appliances, hijacking an operator session exposes the security operations workflow itself. The scope change indicated by the CVSS vector reflects that the impact crosses the boundary of the vulnerable component into the browser origin trusted by the user.

Root Cause

The root cause is improper neutralization of input during web page generation [CWE-79]. Specific HTML elements passed as request parameters are echoed into the response body without context-appropriate encoding. Any characters that carry meaning in HTML, such as <, >, ", and ', are preserved, allowing attackers to break out of the intended data context and inject active content.

Attack Vector

Exploitation is network-based and requires user interaction. The attacker crafts a malicious link pointing at the Central Management interface and delivers it to a valid operator through phishing, chat, or a linked resource. When the operator, already authenticated to Central Management, follows the link, the reflected payload executes in the browser. The script can read session tokens, issue authenticated requests, or exfiltrate data from the management console.

No verified public proof-of-concept code is available. For technical context, refer to the INCIBE Security Notice.

Detection Methods for CVE-2024-0314

Indicators of Compromise

HTTP requests to Central Management URLs containing encoded or literal <script>, onerror=, onload=, or javascript: fragments in query parameters.
Referrer headers on Central Management sessions pointing to unfamiliar external domains that immediately precede administrative actions.
Authenticated API calls from an operator session originating from an unexpected client IP or User-Agent within seconds of a suspicious inbound link click.

Detection Strategies

Inspect web server and reverse-proxy access logs for reflected XSS patterns in parameters submitted to the Central Management interface.
Deploy a Content Security Policy (CSP) report endpoint and monitor CSP violation reports generated by the management console.
Correlate email or messaging gateway URL telemetry against known Central Management hostnames to identify targeted lure delivery.

Monitoring Recommendations

Forward Central Management access logs and browser telemetry into a centralized analytics platform to baseline operator behavior and alert on anomalies.
Alert on session token reuse from a second source address within a short window, which is a common signature of session hijacking after XSS.
Track configuration changes and appliance policy pushes made from Central Management and require secondary verification for changes outside change windows.

How to Mitigate CVE-2024-0314

Immediate Actions Required

Restrict administrative access to Central Management 9.1.1.956704 to trusted management networks and jump hosts only.
Instruct operators to avoid clicking external links while authenticated to Central Management and to use dedicated administrative browsers.
Rotate operator credentials and invalidate active sessions if suspicious reflected content or unexpected administrative activity is observed.

Patch Information

No vendor advisory URL is listed in the enriched CVE data for CVE-2024-0314. Operators of FireEye Central Management 9.1.1.956704 should contact Trellix, the current maintainer of the FireEye product line, for a fixed release or hotfix. Consult the INCIBE Security Notice for related vulnerability information across FireEye products.

Workarounds

Place Central Management behind a web application firewall (WAF) configured to block reflected XSS payloads in query strings and form bodies.
Enforce a strict Content Security Policy on the management interface at the reverse proxy to block inline script execution.
Require multi-factor authentication for all Central Management operators and shorten session lifetimes to limit the value of a hijacked cookie.
Segment the management network so that a compromised operator browser cannot reach arbitrary internet destinations that would receive exfiltrated tokens.
