Exploitability

CWE

KEV

CWE ID	Description
CWE-190	The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

Attack-Flow Graph

Executive Summary

This vulnerability is an integer overflow or wraparound flaw in the Windows IP Over USB Service. It allows an authorized attacker with local access to elevate their privileges on the system.

Detection Guidance

Detection involves checking for the Windows IP Over USB Service running on affected systems. Use PowerShell: Get-Service -Name 'ipoverusbsvc' to verify service status. Check Windows Event Logs for unusual privilege escalation events in Security or System logs.

Impact Analysis

An attacker could exploit this to gain higher privileges than intended, potentially allowing them to install programs, view or delete data, or create new accounts with full user rights.

Compliance Impact

This vulnerability allows local privilege escalation via an integer overflow in the Windows IP Over USB Service. While not directly tied to data exposure, unauthorized privilege escalation could enable attackers to bypass access controls, potentially leading to unauthorized access to sensitive data. This may impact compliance with GDPR (data protection) and HIPAA (health data privacy) by increasing the risk of data breaches or unauthorized processing.

Mitigation Strategies

Apply the latest Windows security updates from Microsoft Update. Disable the IP Over USB Service if not needed using: Set-Service -Name 'ipoverusbsvc' -StartupType Disabled. Restrict local user permissions to reduce attack surface.
