CVE-2009-0080

Status: ModifiedMedium (6.9)—💥 Exploit

The ThreadPool class in Windows Vista Gold and SP1, and Server 2008, does not properly implement isolation among a set of distinct processes that (1) all run under the NetworkService account or (2) all run under the LocalService account, which allows local users to gain privileges by leveraging incorrect thread ACLs to access the resources of one of the processes, aka "Windows Thread Pool ACL Weakness Vulnerability."

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
