CVE-2024-39703 Overview
CVE-2024-39703 is an authenticated command injection vulnerability in ThreatQuotient ThreatQ before version 5.29.3. Authenticated users can execute arbitrary operating system commands by sending a crafted request to a vulnerable API endpoint. The flaw is classified under CWE-77: Improper Neutralization of Special Elements used in a Command. ThreatQ is a threat intelligence platform deployed in security operations and industrial environments, which is why CISA published ICS Advisory ICSA-24-352-01 covering this issue. Successful exploitation gives an attacker code execution in the context of the ThreatQ application backend.
Critical Impact
Authenticated attackers can execute arbitrary commands on the ThreatQ host, compromising confidentiality, integrity, and availability of threat intelligence data.
Affected Products
- ThreatQuotient ThreatQ versions prior to 5.29.3
- ThreatQ platform deployments used in enterprise threat intelligence workflows
- ThreatQ deployments in industrial control system (ICS) environments referenced by CISA advisory ICSA-24-352-01

Technical Details for CVE-2024-39703
Vulnerability Analysis
The vulnerability is a command injection flaw exposed through an API endpoint in the ThreatQ application. An authenticated user submits a crafted request whose parameter values are passed into an operating system command without sufficient neutralization of shell metacharacters. As a result, attacker-controlled input is interpreted by the underlying shell, and injected commands execute with the privileges of the ThreatQ backend process. Because the attack path is network-reachable and requires only low-privilege authentication, any compromised or malicious platform user can pivot to full host command execution.
Root Cause
The root cause is improper neutralization of special elements used in a command ([CWE-77]). An API handler concatenates or passes user-supplied input into a system command invocation without escaping, allow-listing, or using a safe argument-array execution API. ThreatQuotient addressed the issue in ThreatQ 5.29.3.
Attack Vector
The attack vector is network-based against the ThreatQ API. An attacker who holds valid platform credentials, or who has hijacked a session, sends a crafted HTTP request to the vulnerable endpoint. Payload data embeds shell metacharacters or command separators that are executed by the underlying host. No user interaction is required. See the vendor ticket at ThreatQ Helpdesk Ticket 10367 and the CISA ICS Advisory ICSA-24-352-01 for vendor-provided technical detail.
No public proof-of-concept has been released. A verified exploit code sample is not available, so exploitation mechanics are described in prose only.
Detection Methods for CVE-2024-39703
Indicators of Compromise
- Unexpected child processes spawned by the ThreatQ web application or API service, such as sh, bash, python, curl, or wget.
- Outbound network connections initiated by the ThreatQ backend to unknown or non-intelligence-feed destinations.
- API request logs containing shell metacharacters such as ;, |, `, $(, or newline-encoded payloads in parameter values.
- New or modified files under ThreatQ application directories that were not produced by a legitimate upgrade.
Detection Strategies
- Correlate ThreatQ API access logs with process execution telemetry on the host to identify authenticated sessions that precede shell activity.
- Alert on any child process of the ThreatQ application user that is not part of a documented baseline.
- Monitor authentication events for low-privilege accounts that suddenly issue high-volume or malformed API requests.
Monitoring Recommendations
- Forward ThreatQ application, web server, and host process logs to a central analytics platform for correlation and retention.
- Baseline normal ThreatQ API usage per account and alert on deviations in endpoints called, payload sizes, or request rates.
- Track egress traffic from the ThreatQ host and alert on connections that do not match known threat intelligence feed endpoints.
How to Mitigate CVE-2024-39703
Immediate Actions Required
- Upgrade ThreatQ to version 5.29.3 or later as directed by ThreatQuotient.
- Rotate credentials for all ThreatQ platform users and any integration API tokens after patching.
- Review authentication and API logs from before the patch for signs of exploitation, focusing on low-privilege accounts issuing crafted requests.
- Restrict network reachability of the ThreatQ management interface to trusted administrative networks only.
Patch Information
ThreatQuotient fixed CVE-2024-39703 in ThreatQ 5.29.3. Refer to the ThreatQ Helpdesk Ticket 10367, the CISA ICS Advisory ICSA-24-352-01, and ThreatQ Vulnerability Management guidance for upgrade instructions and additional remediation detail.
Workarounds
- Enforce least privilege on ThreatQ accounts and remove unused or inactive platform users until the upgrade is applied.
- Place the ThreatQ API behind a reverse proxy or web application firewall configured to block requests containing shell metacharacters in unexpected parameters.
- Require multi-factor authentication for all ThreatQ user logins to reduce the risk of credential-based access to the vulnerable endpoint.
- Segment the ThreatQ host so it cannot initiate arbitrary outbound connections beyond known threat intelligence feed providers.
