High Nessus Plugin ID 51455

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 8.9


Arbitrary code can be executed on the remote host through Microsoft Data Access Components.


The version of Microsoft Data Access Components (MDAC) installed on the remote Windows host is affected by two vulnerabilities, which could allow arbitrary code execution if a user views a specially crafted web page:

- A buffer overflow in the Open Database Connectivity (ODBC) API used by third-party applications can be triggered by an overly long Data Source Name (DSN) argument. (CVE-2011-0026)

- A failure of MDAC to correctly allocate memory when handling internal data structures in ActiveX Data Objects (ADO) records can be abused to execute arbitrary code. (CVE-2011-0027)


Microsoft has released a set of patches for Windows XP, 2003, Vista, 2008, 7, and 2008 R2.
