Horizon Alert
Summary of the vulnerability and why it matters
This vulnerability affects Microsoft Windows XP and Server 2003 operating systems. A flaw in the NDProxy.sys kernel component allows local users to gain elevated privileges on a system. Such a compromise could lead to significant business risk if an attacker gains control over critical systems or sensitive data.
- Vulnerable Windows kernel component
- Allows local privilege escalation
- Threatens system control and data
Attack Path
How an attacker could exploit the issue
This vulnerability allows for privilege escalation on affected Windows systems when exploited by a local attacker. The exploitation occurs through a crafted application that targets a weakness in the NDProxy.sys kernel driver. Successful exploitation could grant an attacker elevated access, enabling them to perform actions with higher privileges than they would normally have.
- Local user access required.
- Crafted application triggers elevation.
- Attacker gains system control.
Live Threat
Current exploitation, exposure, and threat context
This vulnerability impacts Microsoft Windows XP and Server 2003 operating systems. It allows local users to gain elevated privileges through a crafted application. The potential for damage includes unauthorized access and control over affected systems.

Priority actions
Operational Fix
Recommended remediation, mitigation, and detection steps
This vulnerability impacts Microsoft Windows XP and 2003 Server operating systems, potentially allowing local users to gain elevated privileges. This elevation of privilege could enable an attacker to execute arbitrary code with kernel-level permissions. The risk extends to systems that have not been updated with vendor-provided security patches, potentially affecting data integrity and system availability.
- Identify all affected Windows XP and 2003 Server assets.
- Limit local access to systems.
- Apply vendor security updates and verify installation.
