A remote code execution vulnerability exists in the way that affected Microsoft Office Services and Web Apps parse content in specially crafted files. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2013-3889.

Mitigating Factors

Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors may be helpful in your situation:

  • In a web-based attack scenario, an attacker could host a website that contains a specially crafted Office file that is used to attempt to exploit this vulnerability. In addition, compromised websites and websites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit these websites. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes users to the attacker’s website, and convince them to open the specially crafted Office file.
  • An attacker who successfully exploited this vulnerability could gain the same user rights as the current user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

Workarounds

Workaround refers to a setting or configuration change that does not correct the underlying vulnerability but would help block known attack vectors before you apply the update. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality:

  • Do not open Office files that you receive from untrusted sources or that you receive unexpectedly from trusted sources

    Do not open Office files that you receive from untrusted sources or that you receive unexpectedly from trusted sources. This vulnerability could be exploited when a user opens a specially crafted file.

FAQ

What is the scope of the vulnerability? 
This is a remote code execution vulnerability.

What causes the vulnerability? 
The vulnerability is caused when affected versions of Microsoft Office Services and Web Apps do not properly handle objects in memory while parsing specially crafted Office files.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could cause arbitrary code to run in the security context of the current user. If the current user is logged on with administrative user rights, an attacker could take complete control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

How could an attacker exploit the vulnerability? 
This vulnerability requires that a user open a specially crafted Office file with an affected version of Microsoft Excel software.

In an email attack scenario, an attacker could exploit the vulnerability by sending a specially crafted Office file to the user and then convincing the user to open the file.

In a web-based attack scenario, an attacker would have to host a website that contains a specially crafted Office file that is used to attempt to exploit this vulnerability. In addition, compromised websites and websites that accept or host user-provided content could contain specially crafted content that could exploit this vulnerability. An attacker would have no way to force users to visit a specially crafted website. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link that takes them to the attacker's site, and then convince them to open the specially crafted Office file.

What systems are primarily at risk from the vulnerability? 
Systems where Microsoft Excel is used, including workstations and terminal servers, are primarily at risk. Servers could be at more risk if administrators allow users to log on to servers and to run programs. However, best practices strongly discourage allowing this.

What does the update do? 
The update addresses the vulnerability by correcting the way that affected Microsoft software validates data when parsing specially crafted Office files.

When this security bulletin was issued, had this vulnerability been publicly disclosed? 
No. Microsoft received information about this vulnerability through coordinated vulnerability disclosure.

When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited? 
No. Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers when this security bulletin was originally issued.

An elevation of privilege vulnerability exists in Microsoft SharePoint Server. An attacker who successfully exploited this vulnerability could perform cross-site scripting attacks and run script in the security context of the logged-on user.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2013-3895.

Mitigating Factors

Microsoft has not identified any mitigating factors for this vulnerability.

FAQ

What is the scope of the vulnerability? 
This is an elevation of privilege vulnerability.

What causes the vulnerability? 
The vulnerability is caused when SharePoint Server does not properly protect against a practice known as clickjacking in a SharePoint page.

What is clickjacking ? 
Clickjacking is an online threat whereby an attacker's webpage deceives a user into clicking malicious content by disguising it as legitimate content. For example, a legitimate webpage might be hidden as a "frame" inside a malicious page. When a user clicks in the malicious page, the user is actually clicking something else: such as taking actions on a target SharePoint site on behalf of the user.

What might an attacker use the vulnerability to do? 
An attacker who successfully exploited this vulnerability could read content that the attacker is not authorized to read, use the victim's identity to take actions on the SharePoint site on behalf of the victim, such as change permissions and delete content, and inject malicious content in the browser of the victim.

How could an attacker exploit the vulnerability? 
An unauthenticated attacker could create a specially crafted page and then convince an authenticated SharePoint user to visit the page.

What systems are primarily at risk from the vulnerability? 
Systems that are running an affected version of SharePoint Server are primarily at risk.

What does the update do? 
The update addresses the vulnerability by changing the configuration of SharePoint pages to help provide additional protection against clickjacking attacks.

When this security bulletin was issued, had this vulnerability been publicly disclosed? 
No. Microsoft received information about this vulnerability through coordinated vulnerability disclosure.

When this security bulletin was issued, had Microsoft received any reports that this vulnerability was being exploited? 
No. Microsoft had not received any information to indicate that this vulnerability had been publicly used to attack customers when this security bulletin was originally issued.
