CVE-2024-49600: Dell Power Manager Privilege Escalation

CVE-2024-49600 Overview

Dell Power Manager (DPM) contains an improper access control vulnerability affecting versions prior to 3.17. This security flaw allows a low privileged attacker with local access to the system to potentially exploit the vulnerability, resulting in arbitrary code execution and elevation of privileges. The vulnerability stems from inadequate access control mechanisms within the Dell Power Manager application, enabling unauthorized privilege escalation on affected systems.

Critical Impact

A local attacker with low privileges can exploit this improper access control flaw to execute arbitrary code and escalate privileges to gain elevated system access on Dell systems running vulnerable Power Manager versions.

Affected Products

• Dell Power Manager versions prior to 3.17
• Systems running Dell Power Manager with default configurations
• Enterprise and consumer Dell systems utilizing DPM for power management

Technical Details for CVE-2024-49600

Vulnerability Analysis

This vulnerability is classified as an improper access control issue (CWE-284), which occurs when the Dell Power Manager application fails to properly restrict access to privileged functionality or resources. The flaw allows attackers who already have local access with low-level privileges to bypass security controls and execute code with elevated permissions.

The attack requires local access to the target system but does not require user interaction, making it particularly dangerous in enterprise environments where users may have limited local accounts. Once exploited, an attacker can achieve full compromise of the affected system's confidentiality, integrity, and availability.

Root Cause

The root cause of CVE-2024-49600 lies in improper access control mechanisms within Dell Power Manager. The application fails to adequately validate or enforce permission boundaries, allowing low-privileged users to access functionality or resources that should be restricted to higher privilege levels. This design flaw enables privilege escalation through the exploitation of inadequate authorization checks within the DPM service or application components.

Attack Vector

The attack vector for this vulnerability is local, meaning an attacker must have existing access to the target system. The exploitation path involves:

1. Initial Access: Attacker gains local access to a system running a vulnerable version of Dell Power Manager (prior to version 3.17)
2. Privilege Abuse: The attacker leverages the improper access control flaw to access restricted functionality within the DPM application
3. Code Execution: Through the access control bypass, the attacker can execute arbitrary code
4. Privilege Escalation: The executed code runs with elevated privileges, granting the attacker higher-level system access

The vulnerability can be exploited through the Dell Power Manager service or application components that fail to properly validate user permissions before executing privileged operations. Detailed technical exploitation information is available in the Dell Security Advisory DSA-2024-439.

Detection Methods for CVE-2024-49600

Indicators of Compromise

• Unexpected process spawning from Dell Power Manager service with elevated privileges
• Anomalous access patterns to Dell Power Manager configuration files or registry keys
• Suspicious child processes launched by DpmService.exe or related DPM executables
• Unusual privilege escalation events correlated with Dell Power Manager activity

Detection Strategies

• Monitor for privilege escalation events originating from Dell Power Manager processes using EDR solutions
• Implement application control policies to detect unauthorized code execution within DPM contexts
• Configure Windows Event Log monitoring for process creation events (Event ID 4688) associated with Dell Power Manager
• Deploy behavioral detection rules to identify access control bypass attempts targeting DPM components

Monitoring Recommendations

• Enable detailed logging for Dell Power Manager service activities
• Monitor system integrity and file system changes in Dell Power Manager installation directories
• Implement real-time alerting for privilege escalation attempts on systems with DPM installed
• Conduct regular vulnerability assessments to identify systems running vulnerable DPM versions

How to Mitigate CVE-2024-49600

Immediate Actions Required

• Update Dell Power Manager to version 3.17 or later immediately on all affected systems
• Audit all systems in your environment to identify installations of Dell Power Manager prior to version 3.17
• Implement the principle of least privilege to minimize the impact of potential exploitation
• Consider temporarily restricting local access to systems running vulnerable DPM versions until patching is complete

Patch Information

Dell has released a security update addressing this vulnerability in Dell Power Manager version 3.17. Organizations should apply this update immediately to remediate the improper access control vulnerability. The official security advisory and patch information is available at Dell Security Advisory DSA-2024-439.

Workarounds

• Restrict local user access to systems running Dell Power Manager until the patch can be applied
• Implement application whitelisting to prevent unauthorized code execution in the context of DPM
• Monitor Dell Power Manager processes closely for anomalous behavior using endpoint security solutions
• Consider temporarily disabling Dell Power Manager on critical systems if the functionality is not essential

# Verify Dell Power Manager version on Windows systems
wmic product where "name like 'Dell Power Manager%%'" get name, version

# Check for DPM service status
sc query "DpmService"

# After patching, verify the updated version is installed
