CVE-2024-0316 Overview
CVE-2024-0316 is an improper cleanup vulnerability affecting FireEye Endpoint Security version 5.2.0.958244. The flaw resides in exception handling logic tied to the containment_notify/preview parameter. An unauthenticated remote attacker can send multiple crafted request packets to this parameter to trigger a service outage. The weakness is classified under CWE-460: Improper Cleanup on Thrown Exception and produces a denial of service condition against the endpoint protection service.
Critical Impact
Remote, unauthenticated attackers can disrupt the availability of FireEye Endpoint Security by repeatedly invoking the vulnerable parameter, degrading host protection during the outage window.
Affected Products
- FireEye Endpoint Security version 5.2.0.958244

Technical Details for CVE-2024-0316
Vulnerability Analysis
The vulnerability stems from how FireEye Endpoint Security handles exceptions raised while processing requests to the containment_notify/preview endpoint. When the application throws exceptions during request handling, resources are not released or reset to a clean state. Repeated requests accumulate residual state or consume resources tied to the unhandled exception path. The result is a Denial of Service that affects only the availability of the affected service, not confidentiality or integrity. The attack requires no authentication, no user interaction, and can be initiated over the network with low complexity.
Root Cause
The root cause is improper cleanup on thrown exception ([CWE-460]). When the containment_notify/preview handler encounters an exception, it does not properly release allocated resources, reset object state, or restore invariants. Each malformed or abusive request leaves the service in a degraded state until availability is exhausted.
Attack Vector
An attacker reaches the vulnerable endpoint over the network without credentials. By issuing multiple request packets targeting the containment_notify/preview parameter, the attacker forces the service into repeated exception paths. After enough iterations, the FireEye Endpoint Security service becomes unresponsive and protection on managed hosts is interrupted.
No public proof-of-concept code is available for CVE-2024-0316. Technical details are referenced in the INCIBE Security Notice.
Detection Methods for CVE-2024-0316
Indicators of Compromise
- Repeated HTTP requests targeting the containment_notify/preview parameter from a single or distributed source
- Unexpected restarts, crashes, or unresponsiveness in the FireEye Endpoint Security service
- Gaps in endpoint telemetry coinciding with bursts of inbound requests to the management interface
Detection Strategies
- Inspect web and proxy logs for high-frequency or anomalous requests to containment_notify/preview
- Correlate FireEye Endpoint Security service health events with network traffic spikes to the management endpoint
- Alert on patterns matching exception-triggering payloads sent to FireEye management URIs
Monitoring Recommendations
- Monitor service availability metrics for the FireEye Endpoint Security process and HTTP listeners
- Track source IP addresses generating repeated requests to FireEye management endpoints
- Capture full request/response telemetry on the FireEye management interface for forensic review
How to Mitigate CVE-2024-0316
Immediate Actions Required
- Restrict network access to the FireEye Endpoint Security management interface using firewall ACLs or segmentation
- Identify all hosts running version 5.2.0.958244 and prioritize them for upgrade
- Apply rate limiting on inbound requests to containment_notify/preview at upstream proxies or WAFs
Patch Information
No vendor advisory URL is published in the enriched CVE data. Administrators should consult the vendor (Trellix, the current maintainer of the former FireEye Endpoint Security product line) for an updated build that supersedes 5.2.0.958244. Reference the INCIBE Security Notice on multiple vulnerabilities in FireEye products for vendor coordination details.
Workarounds
- Place the FireEye Endpoint Security management interface behind a VPN or jump host to remove direct internet exposure
- Deploy WAF rules that block or throttle anomalous requests targeting containment_notify/preview
- Allowlist only known management subnets at the network boundary until a patched version is deployed
# Example firewall restriction limiting access to the management interface
iptables -A INPUT -p tcp --dport 443 -s 10.0.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
