Stebner warns: There are a couple of very important caveats that you should read before using this tool to cleanup.
NET Framework bits on your machine: 1. You should try to perform a standard uninstall first. This tool is not designed as a replacement for uninstall, but rather as a last resort for cases where uninstall or repair did not succeed for unusual reasons. A remote code execution vulnerability exists in. NET Framework that could allow an attacker who successfully exploited this vulnerability to make changes to the system with the permissions of the logged-on user.
If a user is logged in 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. 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:.
Microsoft has tested the following workarounds. Although these workarounds will not correct the underlying vulnerability, they help block known attack vectors. When a workaround reduces functionality, it is identified in the following section.
You can help protect against this vulnerability by changing your settings for the Internet security zone to prompt before running ActiveX controls. You can do this by setting your browser security to High. Note If no slider is visible, click Default Level , and then move the slider to High. Note Setting the level to High may cause some Web sites to work incorrectly.
If you have difficulty using a Web site after you change this setting, and you are sure the site is safe to use, you can add that site to your list of trusted sites. This will allow the site to work correctly even with the security setting set to High. Many Web sites that are on the Internet or on an intranet use ActiveX or Active Scripting to provide additional functionality. For example, an online e-commerce site or banking site may use ActiveX Controls to provide menus, ordering forms, or even account statements.
Prompting before running ActiveX Controls or Active Scripting is a global setting that affects all Internet and intranet sites. You will be prompted frequently when you enable this workaround. For each prompt, if you feel you trust the site that you are visiting, click Yes to run ActiveX Controls or Active Scripting.
After you set Internet Explorer to require a prompt before it runs ActiveX controls and Active Scripting in the Internet zone and in the Local intranet zone, you can add sites that you trust to the Internet Explorer Trusted sites zone. This will allow you to continue to use trusted Web sites exactly as you do today, while helping to protect you from this attack on untrusted sites.
We recommend that you add only sites that you trust to the Trusted sites zone. Note Add any sites that you trust not to take malicious action on your computer. These are the sites that will host the update, and it requires an ActiveX Control to install the update. You can help protect against this vulnerability by changing your settings to prompt before running Active Scripting or to disable Active Scripting in the Internet and Local intranet security zone.
To do this, follow these steps:. Note Disabling Active Scripting in the Internet and Local intranet security zones may cause some Web sites to work incorrectly. This will allow the site to work correctly.
Impact of Workaround: There are side effects to prompting before running Active Scripting. Many Web sites that are on the Internet or on an intranet use Active Scripting to provide additional functionality.
For example, an online e-commerce site or banking site may use Active Scripting to provide menus, ordering forms, or even account statements. Prompting before running Active Scripting is a global setting that affects all Internet and intranet sites. For each prompt, if you feel you trust the site that you are visiting, click Yes to run Active Scripting. Read e-mail messages in plain text format to help protect yourself from the HTML e-mail attack vector You can help protect yourself against this vulnerability by changing your e-mail settings to read e-mail messages in plain text using Outlook and later, Outlook Express 6 and later, or Windows Mail.
Impact of Workaround: E-mail messages that are viewed in plain text format will not contain pictures, specialized fonts, animations, or other rich content. Net controls in Internet Explorer 7 You can help protect against this vulnerability by changing your settings to disable. NET controls in the Internet and Local intranet security zone.
Impact of workaround:. NET controls will not load in the zones you have configured. What is the scope of the vulnerability? If successfully exploited, this remote code execution vulnerability could allow the attacker to run arbitrary code as the logged-on user. What causes the vulnerability? An unchecked buffer in the. What might an attacker use the vulnerability to do? An attacker who successfully exploited this vulnerability could make changes to the system with the permissions of the logged-on user.
How could an attacker exploit the vulnerability? An attacker could host a specially crafted Web site that is designed to exploit this vulnerability through Internet Explorer and then persuade a user to view the Web site. This can also include Web sites that accept user-provided content or advertisements, Web sites that host user-provided content or advertisements, and compromised Web sites. These Web sites 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 Web sites. Instead, an attacker would have to persuade users to visit the Web site, typically by getting them to click a link in an e-mail message or in an Instant Messenger request that takes users to the attacker's Web site. After they click the link, they would be prompted to perform several actions. An attack could only occur after they performed these actions. It could also be possible to display specially crafted Web content by using banner advertisements or by using other methods to deliver Web content to affected systems.
What systems are primarily at risk from the vulnerability? This vulnerability requires that a user is logged on and visits a Web site or runs a. NET application locally for any malicious action to occur.
Therefore, any systems where Internet Explorer is used frequently, such as workstations or terminal servers, are at the most risk from this vulnerability. I am running Internet Explorer for Windows Server Does this mitigate this vulnerability? Enhanced Security Configuration is a group of preconfigured settings in Internet Explorer that can reduce the likelihood of a user or administrator downloading and running malicious Web content on a server.
This is a mitigating factor for Web sites that you have not added to the Internet Explorer Trusted sites zone. What does the update do? The update removes the vulnerability by modifying the way that. When this security bulletin was issued, had this vulnerability been publicly disclosed? Microsoft received information about this vulnerability through responsible disclosure. An information disclosure vulnerability exists in. NET Framework that could allow an attacker who successfully exploited this vulnerability to bypass the security features of an ASP.
NET Web site to download the contents of any Web page. The following mitigating factor may be helpful in your situation:. NET developed Web applications that restrict all untrusted input variables, including null bytes, to a range of expected values or characters would not be affected. 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 workaround and states in the discussion whether a workaround reduces functionality:. NET Web Developers may compare values obtained from Internet accessible values such as query string, cookies, or form variables against a list of allowed values and reject any other values that fall outside of this range. This information disclosure vulnerability could allow an attacker to bypass ASP.
NET security features by sending invalid URLs and gaining unauthorized access to configuration files. Note that this vulnerability would not allow an attacker to execute code or to elevate their user rights directly, but it could be used to find information that could be used to try to further compromise the affected system.
