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 is different from CVSS.

VPR Score: 8.9


Arbitrary code can be executed on the remote host through Microsoft Office.


The version of Microsoft Office installed on the remote host has multiple vulnerabilities :

- The path used for loading external libraries is not securely restricted. An attacker could exploit this by tricking a user into opening an Office file in a directory that contains a malicious DLL, resulting in arbitrary code execution. (CVE-2011-0107)

- An unspecified code execution vulnerability exists in Office. A remote attacker could exploit this by tricking a user into opening a maliciously crafted Office file. (CVE-2011-0977)


Microsoft has released a set of patches for Office XP, 2003, and 2007.
