CVE-2024-34788: Ivanti Endpoint Manager Auth Bypass Flaw

CVE-2024-34788 Overview

CVE-2024-34788 is an improper authentication vulnerability [CWE-287] in the web component of Ivanti Endpoint Manager Mobile (EPMM) prior to version 12.1.0.1. The flaw allows a remote authenticated user with low privileges to access potentially sensitive information [CWE-200]. Ivanti disclosed the issue in its July 2024 security advisory covering multiple EPMM vulnerabilities. The vulnerability affects the confidentiality of data managed by the EPMM web interface but does not impact integrity or availability.

Critical Impact
Authenticated remote attackers can retrieve sensitive information from Ivanti EPMM instances running versions prior to 12.1.0.1 by bypassing authentication controls in the web component.

Affected Products

Ivanti Endpoint Manager Mobile (EPMM) versions prior to 12.1.0.1
Ivanti EPMM web component
On-premises EPMM deployments managing enterprise mobile fleets

Technical Details for CVE-2024-34788

Vulnerability Analysis

The vulnerability resides in the web component of Ivanti EPMM, the on-premises platform used to manage mobile devices across enterprise environments. An authenticated remote attacker can exploit improper authentication logic to retrieve sensitive information that should be restricted. The attack requires network access to the EPMM web interface and valid low-privilege credentials.

Ivanti classifies the issue under [CWE-287: Improper Authentication] combined with [CWE-200: Exposure of Sensitive Information to an Unauthorized Actor]. The confidentiality impact is high, while integrity and availability are not affected. Because EPMM stores device inventory, user data, and mobile configuration profiles, exposed information can support follow-on attacks against managed endpoints.

Root Cause

The root cause is insufficient authentication enforcement within specific endpoints of the EPMM web component. Authorization checks fail to properly restrict access to protected resources, enabling a low-privileged account to reach data outside its intended scope. Ivanti did not publish detailed exploitation internals in the advisory.

Attack Vector

Exploitation occurs over the network against the EPMM administrative or user-facing web interface. The attacker must already possess valid credentials with low privileges. No user interaction is required, and attack complexity is low. Public proof-of-concept code is not currently available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Technical specifics of the vulnerable endpoint have not been disclosed by Ivanti. Refer to the Ivanti Security Advisory July 2024 for vendor guidance.

Detection Methods for CVE-2024-34788

Indicators of Compromise

Unexpected authenticated requests from low-privilege accounts to EPMM administrative endpoints
Access patterns targeting resources outside the authenticated user's assigned scope
Unusual data retrieval volume from the EPMM web component by non-administrative users

Detection Strategies

Review EPMM web server access logs for anomalous URL access by low-privileged accounts
Correlate authentication events with sensitive resource access to identify authorization gaps
Monitor for enumeration behavior such as sequential object identifier access or repeated requests to protected paths

Monitoring Recommendations

Centralize EPMM audit logs and web access logs in a SIEM for continuous analysis
Alert on access from unexpected source IP ranges or outside normal operating hours
Baseline normal administrative activity to surface deviations from established patterns

How to Mitigate CVE-2024-34788

Immediate Actions Required

Upgrade Ivanti EPMM to version 12.1.0.1 or later as directed by the vendor advisory
Audit existing EPMM user accounts and remove unused or unnecessary low-privilege accounts
Rotate credentials for any accounts suspected of unauthorized use prior to patching

Patch Information

Ivanti released fixed versions in the July 2024 EPMM Security Advisory. Administrators should apply version 12.1.0.1 or later to remediate CVE-2024-34788. Confirm the patched build is deployed across all EPMM nodes in clustered environments.

Workarounds

Restrict network access to the EPMM web component using firewall rules or VPN requirements
Enforce multi-factor authentication (MFA) on all EPMM accounts to reduce credential abuse risk
Apply least-privilege principles when assigning EPMM administrative roles

bash

# Example: restrict EPMM web interface access with iptables
iptables -A INPUT -p tcp --dport 443 -s 10.0.0.0/8 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP
