CVE-2016-0100: Windows Vista and Server 2008 library loading flaw allows privilege escalation

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 19 September 2026. Confidence: medium.

high priorityCVSS 8.4 with local no-auth vector and high EPSS percentile, though no confirmed active exploitation or KEV listing.

What it is

Microsoft Windows Vista SP2 and Server 2008 SP2 mishandle library loading, failing to properly validate input when loading libraries. A local user can exploit this with a crafted application to gain elevated privileges on the affected system.

Impact

An attacker who runs a crafted application locally can gain privileges, potentially achieving full control of confidentiality, integrity, and availability on the host.

Attack surface

The vulnerability is reached locally by executing a crafted application; no authentication or user interaction beyond running the application is required per the CVSS vector (AV:L/PR:N/UI:N).

Exploitation

Not listed in CISA KEV and no public exploit references are tagged; EPSS indicates a high probability of exploitation activity (0.58, 99th percentile), but the record does not confirm active exploitation.

What to do

• Apply Microsoft security bulletin MS16-025 for Windows Vista SP2 and Server 2008 SP2.
• Restrict execution of untrusted applications and binaries on affected systems.
• Enforce least privilege so users cannot run arbitrary code with elevated rights.
• Monitor for and block known malicious library loading patterns where feasible.
• Plan migration off end-of-support Windows Vista and Server 2008 platforms.

Detection

• Monitor process creation for unexpected or suspicious child processes spawned from user-writable directories.
• Audit DLL/library load events for unsigned or unusual paths on Vista and Server 2008 hosts.
• Review Windows security event logs for privilege escalation indicators such as token elevation anomalies.
• Track execution of newly written binaries in user-writable locations that may attempt library hijacking.
