Microsoft Windows LocalSystem privilege escalation
| win-localsystem-privilege-escalation (41880) |  High Risk |
Description:
Microsoft Windows could allow a local authenticated attacker to gain elevated privileges, caused by an error when executing code in the security context of the NetworkService or LocalService accounts. An attacker could exploit this vulnerability via IIS (using ISAPI filters and extensions or ASP.NET code running in full trust), SQL Server (when administrative privileges are granted to load and run code), and the Microsoft Distributed Transaction Coordinator (MSDTC) service, to gain access to resources in processes that are also running as NetworkService or LocalService, and possibly execute arbitrary code with LocalSystem privileges.
Platforms Affected:
- Microsoft, Windows 2003 Server x64
- Microsoft, Windows 2003 Server SP2 Itanium
- Microsoft, Windows 2003 Server SP2 x64
- Microsoft, Windows 2003 Server SP2
