CVE-2024-47908: Ivanti Cloud Services Appliance RCE Flaw

CVE-2024-47908 Overview

CVE-2024-47908 is an operating system command injection vulnerability in the administrative web console of Ivanti Cloud Services Appliance (CSA) versions prior to 5.0.5. A remote, authenticated attacker holding administrative privileges can inject arbitrary operating system commands and achieve remote code execution on the underlying appliance. The flaw is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command. Ivanti published a coordinated security advisory documenting the issue and the fixed version.

Critical Impact
Successful exploitation grants full remote code execution on the Ivanti CSA appliance, exposing sensitive traffic, credentials, and connected internal systems to compromise.

Affected Products

Ivanti Cloud Services Appliance (CSA) versions before 5.0.5
Deployments exposing the admin web console to authenticated administrative users
Environments using CSA as a gateway between managed endpoints and Ivanti management servers

Technical Details for CVE-2024-47908

Vulnerability Analysis

The vulnerability resides in the administrative web console of Ivanti CSA. Input supplied through administrator-accessible functionality is passed to an operating system shell without sufficient neutralization of shell metacharacters. An authenticated administrator can therefore append or embed additional commands that execute in the context of the appliance service account.

The issue is tracked under CWE-78, the standard weakness for OS command injection. Because Ivanti CSA brokers communication between managed devices and internal management infrastructure, code execution on the appliance provides an attacker with a pivot into segmented enterprise networks. The public EPSS estimate of 22.331% places this CVE in the 97th percentile for probability of exploitation activity, indicating elevated interest despite the required authentication.

Root Cause

The root cause is improper neutralization of user-controlled input that is later incorporated into a system command string. The console concatenates administrator input into a command executed by the underlying shell, rather than using safe process invocation with parameterized arguments. Any character with shell meaning, such as ;, |, &, or backticks, is interpreted by the shell rather than treated as literal data.

Attack Vector

Exploitation requires network access to the CSA admin web console and valid administrator credentials. An attacker with those prerequisites, obtained through credential theft, phishing, or reuse of previously leaked credentials, submits a crafted value to a vulnerable console parameter. The injected payload runs on the appliance with the privileges of the web console process, enabling command execution, file access, and lateral movement.

No public proof-of-concept exploit is currently listed for this CVE. Refer to the Ivanti Security Advisory for vendor-confirmed technical scope.

Detection Methods for CVE-2024-47908

Indicators of Compromise

Unexpected child processes such as sh, bash, nc, curl, or wget spawned by the CSA web console service
Outbound network connections from the CSA appliance to unfamiliar hosts, especially over non-standard ports
New or modified files in web-accessible directories, cron paths, or /tmp on the appliance
Administrator logins from atypical source addresses immediately preceding suspicious process activity

Detection Strategies

Monitor CSA admin web console access logs for requests containing shell metacharacters (;, |, &, backticks, $())
Correlate administrative session activity with process execution telemetry on the appliance host
Alert on any interactive shell or scripting interpreter launched as a child of the web server process
Baseline normal administrator command patterns and flag deviations for review

Monitoring Recommendations

Forward CSA syslog, authentication, and process telemetry to a centralized SIEM or data lake for retention and correlation
Track privileged account use on Ivanti management infrastructure and alert on new admin sessions from unrecognized geolocations
Review appliance configuration changes and audit trails on a recurring cadence

How to Mitigate CVE-2024-47908

Immediate Actions Required

Upgrade Ivanti Cloud Services Appliance to version 5.0.5 or later without delay
Restrict network access to the CSA admin web console to trusted management networks only
Enforce multi-factor authentication for all administrator accounts and rotate credentials suspected of exposure
Audit CSA logs for signs of prior exploitation before and after applying the patch

Patch Information

Ivanti addressed CVE-2024-47908 in Cloud Services Appliance version 5.0.5. Administrators should follow the remediation guidance in the Ivanti Security Advisory for CVE-2024-47908 and CVE-2024-11771. Confirm the running version after upgrade and validate that no legacy CSA instances remain reachable.

Workarounds

Limit admin console reachability through firewall access control lists or a bastion host
Segment the CSA appliance from general user networks to reduce credential exposure paths
Disable or remove administrator accounts that are no longer required and enforce least privilege for remaining accounts

bash

# Example: restrict CSA admin console access to a management subnet
iptables -A INPUT -p tcp --dport 443 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
