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.

Synopsis

An application installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The Microsoft Office application, Office Web Apps, or SharePoint Server installed on the remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities :

- An arbitrary code execution vulnerability exists in Microsoft Outlook due to improper parsing of email messages. An unauthenticated, remote attacker can exploit this, via a specially crafted email message, to execute arbitrary code. (CVE-2017-0106)

- An information disclosure vulnerability exists in Microsoft Office due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted Excel file, to disclose the contents of memory.
(CVE-2017-0194)

- A cross-site scripting (XSS) vulnerability exists in Office Web Apps Server due to improper validation of input before returning it to users. An authenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2017-0195)

- An arbitrary code execution vulnerability exists in Microsoft Office due to improper validation of input before loading dynamic link library (DLL) files. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted Office document, to execute arbitrary code. (CVE-2017-0197)

- An arbitrary code execution vulnerability exists in Microsoft Office and Windows WordPad due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted file, to execute arbitrary code. Note that this vulnerability is being utilized to spread the Petya ransomware. (CVE-2017-0199)

- A security feature bypass vulnerability exists in Microsoft Office due to improper parsing of file formats. An unauthenticated, remote attacker can exploit this, by convincing a user into opening a specially crafted file, to bypass security features.
(CVE-2017-0204)

- A spoofing vulnerability in Microsoft Outlook due to improper validation of input passed via HTML tags. An unauthenticated, remote attacker can exploit this, by sending an email with specific HTML tags, to display a malicious authentication prompt and gain access to a user's authentication information or login credentials.
(CVE-2017-0207)

- An unspecified flaw exists in Microsoft Office in the Encapsulated PostScript (EPS) filter that allows an attacker to have an unspecified impact. (CVE-2017-2605)
