Technical Details for CVE-2024-43582

Vulnerability Analysis

This vulnerability is a high-severity use-after-free issue within the Remote Desktop Protocol (RDP) on certain versions of Microsoft Windows. The improper handling of objects in memory can result in code execution.

Root Cause

The issue stems from improper memory management in the RDP server’s handling of certain types of network packets, resulting in a use-after-free condition.

Attack Vector

The vulnerability is exploitable remotely over the network without authentication, making it a critical vector for attackers, particularly in exposed RDP environments.

Detection Methods for CVE-2024-43582

Indicators of Compromise

Unusual network traffic on port 3389
Unexpected RDP connections
Presence of suspicious processes or files indicating remote access

Detection Strategies

Network traffic analysis tools should be tuned to detect anomalies in RDP protocol negotiations. Endpoint detection systems should monitor for unexpected changes in system processes and registry keys related to RDP service.

Monitoring Recommendations

Implement real-time monitoring to capture unusual login attempts. SentinelOne’s advanced behavioral analytics can identify deviations indicative of exploitation attempts.

How to Mitigate CVE-2024-43582

Immediate Actions Required

Disable RDP if not necessary in your environment
Restrict access to RDP using network-level authentication
Enable firewalls to block unauthorized RDP connections

Patch Information
