SYMPTOMS
Microsoft has released a patch for Microsoft Content Management Server (MCMS) 2001 that includes updates for the following security vulnerabilities:
- A buffer overrun in a low-level function that performs user authentication. At least one Web page that is included with CMS 2001 passes input directly to the function, thereby potentially providing a way for an attacker to overrun the buffer. The result of exploiting the vulnerability can be to either cause CMS to fail, or to run code in the context of the CMS service (which runs as Local System).
- A vulnerability resulting from the confluence of two flaws that affect a function that permits files to be uploaded to the server. The first flaw lies in how the function authenticates requests, and permits any user to submit an upload request. The second results because it is possible to override the upload location; although the function should upload files to a folder that only privileged users can access, it can be overridden to upload a file to a temporary folder that does allow unprivileged users to call it. By exploiting the two flaws in tandem, an attacker can upload an .asp or other file to the server, in a location from which it can be executed.
- A SQL injection vulnerability that affects a function that services requests for image files and other resources. By exploiting the vulnerability, an attacker can run SQL commands on the server. That is, the attacker can add, change, or delete data in the CMS database, and the attacker can also run operating system commands on the server.
RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that you determine are at risk of attack. Evaluate your computer's physical accessibility, network and Internet connectivity, and other factors to determine the degree of risk to your computer. See the associated Microsoft Security Bulletin to help determine the degree of risk. This fix may receive additional testing. If your computer is sufficiently at risk, Microsoft recommends that you apply this fix now. Otherwise, wait for the next Microsoft Content Management Server 2001 service pack that contains this fix.
To resolve this problem immediately, download the fix by following the instructions later in this article or contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:
NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The usual support costs will apply to additional support questions and issues that do not qualify for the specific update in question.
