Summary
CVE-2016-0099 is a high-severity Classic Buffer Overflow (CWE-120) vulnerability in Microsoft Windows Server 2008. Its CVSS base score is 7.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); ranked in the top 2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The vulnerability is an elevation of privilege flaw in the Secondary Logon Service of Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8.1, Windows Server 2012 Gold and R2, Windows RT 8.1, and Windows 10 Gold and 1511. It stems from improper processing of request handles and is tracked as CWE-120, carrying a CVSS 3.1 base score of 7.8.
Local authenticated users can exploit the issue by running a crafted application on an affected system, resulting in the ability to gain higher privileges on the host. The attack requires no user interaction beyond executing the malicious code and does not need network access.
Microsoft addressed the vulnerability in security bulletin MS16-032, which supplies patches for the listed Windows versions; administrators should apply the updates according to the bulletin guidance. Public exploit code for the flaw has been published on Exploit-DB.
The issue enables straightforward local privilege escalation on unpatched systems and has been publicly demonstrated since its disclosure in March 2016.
