CVE-2024-11772: Ivanti Cloud Services Appliance RCE Flaw

CVE-2024-11772 Overview

CVE-2024-11772 is a command injection vulnerability [CWE-77] in the administrator web console of Ivanti Cloud Services Appliance (CSA) versions prior to 5.0.3. A remote authenticated attacker holding admin privileges can inject operating system commands through the console to achieve remote code execution on the appliance. Ivanti disclosed the issue alongside CVE-2024-11639 and CVE-2024-11773 in a coordinated advisory.

Critical Impact
Successful exploitation grants attackers arbitrary command execution on the CSA host, compromising confidentiality, integrity, and availability of the appliance and any downstream systems it manages.

Affected Products

Ivanti Cloud Services Appliance (CSA) versions before 5.0.3
Deployments exposing the CSA administrator web console
Environments using CSA as a gateway for Ivanti EPM or related products

Technical Details for CVE-2024-11772

Vulnerability Analysis

CVE-2024-11772 stems from insufficient neutralization of special elements used in an OS command [CWE-77] within the CSA administrator web console. The console accepts input that is passed to an underlying shell or command interpreter without adequate sanitization. An authenticated admin can append shell metacharacters to legitimate console parameters, causing the appliance to execute attacker-supplied commands under the privileges of the web service account.

The attack requires network reachability to the admin console and valid administrator credentials. Because CSA typically runs with elevated service privileges, injected commands can pivot to system-level actions such as reading configuration secrets, modifying appliance state, or establishing persistent access.

Root Cause

The root cause is improper input validation and unsafe construction of shell commands from user-controlled data in administrative endpoints. Instead of using parameterized system calls or strict allow-lists, the affected code paths concatenate input into command strings interpreted by a shell, permitting characters such as ;, |, &&, and backticks to break out of the intended command context.

Attack Vector

The attack vector is network-based and requires prior admin authentication. An attacker who has stolen or otherwise obtained admin credentials, or who chains this issue with an authentication bypass such as CVE-2024-11639, submits a crafted request to a vulnerable admin console endpoint. The injected payload executes on the appliance operating system with service-level privileges, enabling full remote code execution.

No public proof-of-concept exploit is currently listed for this CVE, and it is not present on the CISA Known Exploited Vulnerabilities catalog. The EPSS score of 7.703% (94.038 percentile) indicates elevated relative exploitation likelihood compared to the broader CVE population. See the Ivanti Security Advisory for vendor technical details.

Detection Methods for CVE-2024-11772

Indicators of Compromise

Unexpected child processes spawned by the CSA web server process, particularly shells such as /bin/sh, /bin/bash, or utilities like curl, wget, nc, and python.
Outbound network connections from the CSA appliance to unfamiliar external hosts shortly after admin console activity.
New or modified files in web-accessible directories, cron entries, or systemd units on the CSA appliance.
Admin console access log entries containing shell metacharacters (;, |, `, $() in request parameters.

Detection Strategies

Review CSA web console access and audit logs for administrator sessions issuing requests containing suspicious characters or unusually long parameter values.
Correlate admin authentication events with subsequent process execution telemetry on the appliance to detect command injection chains.
Alert on any process creation where the parent is the CSA web service and the child is a shell interpreter or network utility.

Monitoring Recommendations

Forward CSA syslog, web server, and authentication logs to a centralized SIEM for retention and correlation.
Monitor administrator account usage for logins from unexpected source IPs, off-hours activity, or high-frequency configuration changes.
Track appliance file integrity for changes to /etc, web root, and scheduled task locations.

How to Mitigate CVE-2024-11772

Immediate Actions Required

Upgrade Ivanti CSA to version 5.0.3 or later as specified in the vendor advisory.
Restrict network access to the CSA administrator web console to trusted management networks or VPN only.
Rotate all CSA administrator credentials and audit admin account inventory for unused or shared accounts.
Review CSA logs for indicators of prior exploitation and investigate any suspicious admin activity.

Patch Information

Ivanti addressed CVE-2024-11772 in Cloud Services Appliance version 5.0.3. Refer to the Ivanti Security Advisory for CVE-2024-11639, CVE-2024-11772, and CVE-2024-11773 for upgrade instructions and release notes.

Workarounds

Block internet exposure of the CSA admin console by placing it behind a firewall or reverse proxy with source IP restrictions.
Enforce multi-factor authentication and strong password policies for all administrative accounts.
Segment the CSA appliance from sensitive internal systems to limit blast radius of a compromise.

bash

# Example firewall restriction limiting CSA admin console access to a management subnet
iptables -A INPUT -p tcp --dport 443 -s 10.10.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
