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: 5.5
Synopsis
A Microsoft Office application installed on the remote host is affected by multiple vulnerabilities.
Description
The versions of Microsoft Word and Excel installed on the remote host are missing a security update. They are, therefore, affected by multiple vulnerabilities :
- A security bypass vulnerability exists in Excel due to improper handling of formatted inline macros that are attached to objects within a workbook. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted workbook, to execute macros outside the constraints of the Macro Security Model. (CVE-2002-0616)
- A security bypass vulnerability exists in Excel due to improper handling of macros in a workbook when it is opened through a hyperlink associated with a drawing shape in another workbook. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted workbook, to execute macros outside the constraints of the Macro Security Model.
(CVE-2002-0617)
- A flaw exists in the Macro Security Model in Excel due to a failure to correctly detect the presence of HTML scripting within an Excel workbook that contains an XSL stylesheet. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted file, to execute arbitrary HTML scripts.
(CVE-2002-0618)
- A flaw exists in Word when opening Mail Merge documents that have been saved in HTML format. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted document, to execute arbitrary VBA code in Access. (CVE-2002-0619)
Solution
Microsoft has released a set of patches for Excel 2000, Excel 2002, and Word 2002.
