Microsoft Security Bulletin Ms02-069
In it, we detailed a work-around procedure that customers could implement to protect themselves against a publicly disclosed vulnerability. Instead, he or she would need to lure them there, typically by getting them to click a link that would take them to the attacker's site. That is, just because an email says it came from someone you trust, it doesn't mean that it actually did - and even if it did come from that person's email Yes. Check This Out
IIS can be configured to run with fewer than administrative privileges. Potentially, any system that has MDAC, and in particular RDS, installed and running is at risk. An attacker could use this issue to cause Internet Explorer to fail on a user's system. By design, COM objects should only be available to trusted Java programs because of the functionality they expose. Clicking Here
How could the attacker exploit the vulnerability? The attacker would need to create a web page that, when opened, would invoke the HTML directive we discussed above, and cause the buffer overrun Customers with VBScript 5.6 should install the patch available for IE 6.0. Home users can select any username they like; corporate users may be required to select a username that's some derivation of their real name.
Is this correct? No. In order for a web server to be at risk from the vulnerability, both of the following must be true: A vulnerable version of MDAC must be installed on the server. By design, IE should only open a file on a web site using the application that's registered to that type of file, and even then only if it's on a list Windows 95, 98 and 98SE: In Control Panel, double-click Network.
In addition, in the first attack scenario discussed above, the effect of exploiting the vulnerability would depend on the specific privileges of the user who subsequently logged onto the system. A vulnerability that could enable a web page to run a script even if the user has disabled scripting. Knowledge Base articles can be found on the Microsoft Online Support web site.Technical support is available from Microsoft Product Support Services. https://technet.microsoft.com/en-us/library/security/ms02-065.aspx This control, which is not installed by default with Internet Explorer, and is normally only used by developers or support professionals, has been retired and is no longer supported.
The vulnerability could only be exploited by an attacker who could authenticate to an affected SQL Server or has permissions to execute queries directly to the server The vulnerability could only The issue could be exploited in exactly the same way as discussed above: by creating a Java applet that exploited it, then hosting the applet as part of a web page While knowing a username would not in itself pose a security risk, it could be useful for reconnaissance purposes. The IE 5.5 patch can be installed on systems running IE 5.5 Service Pack 1 or Service Pack 2.
Web server. A malicious user could exploit this vulnerability by using scripting to extract the contents of frames in other domains, then sending that content back to their web site. In the worst case, this could enable the attacker to take serious action such as creating, modifying, or deleting data file, communicating with web sites, or reformatting the hard drive.

The VM doesn't correctly parse a particular type of URL. http://3ecommunications.net/microsoft-security/microsoft-security-bulletin-ms03-018.html Disclaimer: The information provided in the Microsoft Knowledge Base is provided "as is" without warranty of any kind. What causes the vulnerability? Knowledge Base articles can be found on the Microsoft Online Support web site.
Microsoft recommends that SQL 2000 and MSDE 2000 customers apply the patch from MS02-061. Is there a separate patch for MDAC and Internet Explorer? Other information: Support: Microsoft Knowledge Base article 810030 discusses this issue and will be available approximately 24 hours after the release of this bulletin. http://3ecommunications.net/microsoft-security/microsoft-security-bulletin-ms07-058.html Who can create scheduled jobs? Any user can create a scheduled job, but the SQL Server Agent will only execute a particular job step if the requester has appropriate privileges.
What are Internet Explorer security zones? Internet Explorer Security Zones are a system that divides online content into categories, or zones based on its trustworthiness. An attacker could seek to exploit this by using HTML e-mail or by using an ActiveX control. Specifically, Outlook Express 6 and Outlook 2002 (which ships as part of Office XP) disable Java by default, and Outlook 98 and 2000 disable it if the Outlook Email Security Update
Best practices strongly recommends against allowing untrusted users to load and run queries of their construction.
In addition, this could be used to mis-represent the URL in the address bar in a window opened from their site. Support: Microsoft Knowledge Base article Q328970 discusses this issue and will be available approximately 24 hours after the release of this bulletin. Likewise, if the attacker made it appear that the applet had come from a network share, he or she would gain the ability to read files from that location. A vulnerability that could, under unusual conditions, enable an attacker to interpose a program from his or her web site onto a third-party web site.
Inclusion in future service packs: The fix for this issue will be included in MDAC 2.5 Service Pack 5 and in MDAC 2.7 Service Pack 2. The vulnerability is subject to a number of constraints: The user would have to first visit the attacker's website, and would then have to follow a link containing a malformed URL This could require significant social engineering. http://3ecommunications.net/microsoft-security/microsoft-security-bulletin-ms08-031.html The version information has the same format as that of the FullInstallVer value, x.xx.yyyy.y, where x.xx is the version number.
What is the Microsoft VM? To verify the individual files, consult the file manifest in Knowledge Base article Q314147 Windows 2000: To verify that the patch has been installed on the machine, confirm that the following Shouldn't there be a warning message? A warning message is generated anytime there's an error associated with a digital signature (e.g., a bad signature or expired certificate) or the signer isn't trusted. Specifically, the Security Zones mechanism lets you specify (via the security setting labeled "Active Scripting") whether scripts should run, and under what conditions.
The Web page could be hosted on a Web site or sent directly to the user in an e-mail message. When the response from the database arrives, the Business Logic Tier may need to translate the results into a form that's more meaningful for the user. MIME types were first developed so that Internet mail clients could handle file attachments intelligently, but their use has been extended so that browsers too can use them to handle files The flaw allows script to violate IE's Cross-Domain Security Model in a way that would enable a web site to read data in a frame belonging to another domain.
But two types of systems are at special risk: Web servers. How does the patch eliminate this vulnerability? The patch restores proper buffer handling to the HTML directive at issue in this vulnerability. The attacker would need to know the name and location of the file on the user's computer Even if successfully exploited, the attacker could only view files that can be opened How did the JDBC APIs function in earlier versions of the Microsoft VM?
As a result, systems running anything other than Windows XP are almost certainly at risk and need the patch. It could be possible for an attacker to use this vulnerability to run arbitrary code on a user's system. Chip Andrews of www.sqlsecurity.com and Timothy Mullen for reporting additional information on these issues. Users should apply MS03-033, which also contains a fix for an additional security vulnerability.
Web clients - including Web servers that are sometimes used for Web browsing - have fewer options. What causes the vulnerabilities? What are COM objects? Even if a vulnerable version of MDAC were installed, a web server would only be at risk if RDS were enabled.
