Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

This is a use-after-free vulnerability in Windows Message Queuing. It allows an unauthorized attacker to execute arbitrary code over a network by exploiting a flaw where a program continues to use memory after it has been freed.

Detection Guidance

Detecting this vulnerability requires monitoring for unusual activity in Windows Message Queuing services. Check for unexpected crashes in services.exe or lsass.exe processes. Review Windows Event Logs for Application or System events with Event IDs 1000, 1001, or 1005 which may indicate application crashes. Use Process Explorer or similar tools to inspect memory usage patterns of mqsvc.exe or related services.

Impact Analysis

An attacker could remotely execute malicious code on your system, potentially taking control of it, stealing data, or installing malware. This could lead to system compromise, data breaches, or further network infiltration.

Compliance Impact

This vulnerability allows remote code execution via a use-after-free flaw in Windows Message Queuing, which could lead to unauthorized access or data breaches. Such breaches may violate GDPR's data protection requirements or HIPAA's safeguards for protected health information, depending on the affected system and data involved.

Mitigation Strategies

Apply the latest security updates from Microsoft for Windows Message Queuing components. Disable the Message Queuing service if not required. Monitor network traffic for suspicious activity targeting port 1801.
