Summary

Microsoft Windows XP Professional SP2, Vista, and Server 2003 and 2008 does not properly assign activities to the (1) NetworkService and (2) LocalService accounts, which might allow context-dependent attackers to gain privileges by using one service process to capture a resource from a second service process that has a LocalSystem privilege-escalation ability, related to improper management of the SeImpersonatePrivilege user right, as originally reported for Internet Information Services (IIS), aka Token Kidnapping.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
