CVE-2024-5717: Logsign Unified SecOps Platform RCE Vulnerability

CVE-2024-5717 Overview

CVE-2024-5717 is a command injection vulnerability in Logsign Unified SecOps Platform that allows remote attackers to execute arbitrary code as root. The flaw resides in the HTTP API, where a user-supplied string is passed to a system call without proper validation. While the endpoint requires authentication, the existing authentication mechanism can be bypassed, effectively lowering the barrier to exploitation. The issue was reported through the Trend Micro Zero Day Initiative as ZDI-CAN-24165 and maps to [CWE-78] OS Command Injection.

Critical Impact
Successful exploitation grants root-level remote code execution on the security operations platform itself, exposing collected logs, detections, and downstream integrations to attacker control.

Affected Products

Logsign Unified SecOps Platform (versions prior to 6.4.8)
Deployments exposing the HTTP API to untrusted networks
On-premises Logsign installations running as root

Technical Details for CVE-2024-5717

Vulnerability Analysis

The vulnerability is a classic OS command injection in the HTTP API of Logsign Unified SecOps Platform. An attacker sends a crafted request containing shell metacharacters or additional command tokens inside a parameter that the backend concatenates into a system call. Because the platform process runs as root, the injected commands execute with full privileges on the underlying host.

Authentication is nominally required to reach the vulnerable endpoint. However, the ZDI advisory notes that the existing authentication mechanism can be bypassed, making the vulnerability reachable by unauthenticated network attackers in practice. This combination yields high impact to confidentiality, integrity, and availability of the SecOps platform.

Compromise of a SecOps platform is particularly damaging. Attackers gain access to aggregated logs, detection rules, and integration credentials that reach into the rest of the environment.

Root Cause

The root cause is missing input validation on a user-supplied string before it is passed to a system call. The API handler does not enforce an allow-list, does not escape shell metacharacters, and does not use a safe process execution API that separates arguments from the command interpreter.

Attack Vector

Exploitation is performed over the network against the HTTP API. The attacker first bypasses authentication using the weakness in the login mechanism, then submits a request whose parameter contains shell metacharacters chained to the intended command. The server executes the resulting string in a shell context, running attacker commands as root. No user interaction is required.

See the Zero Day Initiative Advisory ZDI-24-617 for the technical write-up.

Detection Methods for CVE-2024-5717

Indicators of Compromise

Unexpected child processes of the Logsign platform service (for example, sh, bash, curl, wget, python, nc) spawned by the HTTP API worker.
New outbound network connections initiated by the Logsign host to unfamiliar IP addresses shortly after HTTP API requests.
Modifications to system files, cron entries, or authorized_keys created by the Logsign service account (root).
HTTP API access log entries containing shell metacharacters such as ;, |, `, $(, or URL-encoded equivalents.

Detection Strategies

Alert on any process execution where the parent is the Logsign HTTP API service and the child is a shell, scripting interpreter, or network utility.
Inspect web access logs for authentication-bypass patterns followed by API calls containing command separators.
Correlate authentication events with subsequent privileged process activity on the same host to surface bypass-then-execute sequences.

Monitoring Recommendations

Forward Logsign platform host telemetry, including process, file, and network events, to your SIEM or data lake for behavioral analysis.
Baseline the normal process tree of the Logsign service and alert on deviations, particularly root-level shell activity.
Monitor egress from the Logsign server for reverse-shell patterns and beaconing.

How to Mitigate CVE-2024-5717

Immediate Actions Required

Upgrade Logsign Unified SecOps Platform to version 6.4.8 or later, per the Logsign Version 6.4.8 Release Notes.
Restrict network reachability of the HTTP API to trusted management networks only.
Rotate credentials, API tokens, and integration secrets stored on or accessible to the Logsign server, assuming potential compromise.
Review host and platform logs for the indicators listed above and initiate incident response if matches are found.

Patch Information

Logsign addressed the command injection and the authentication bypass in Logsign Unified SecOps Platform version 6.4.8. Administrators should apply this release or later. Refer to the vendor release notes for upgrade prerequisites and post-upgrade validation steps.

Workarounds

Place the HTTP API behind a reverse proxy or VPN that enforces strong authentication and source IP allow-listing.
Block access to the vulnerable API endpoints at the network perimeter until the patch is applied.
Run the Logsign service under a lower-privileged account where supported, to reduce blast radius from any residual command injection.

bash

# Example: restrict Logsign HTTP API to a management CIDR using iptables
iptables -A INPUT -p tcp --dport 443 -s 10.10.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
