Microsoft Virtual Machine Multiple JDBC Vulnerabilities

Risk

High

Date Discovered

September 19, 2002

Description

Microsoft Virtual Machine contains three vulnerabilities that could allow a remote attacker to execute code on the vulnerable system. Successful exploitation could lead to a complete system compromise. The first vulnerability allows remote execution of DLLs. These would be executed in the context of the currently logged in user. The second vulnerability involves improper validation in handles provided as input. Supplying malformed data would cause the application hosting the virtual machine to fail. The third vulnerability allows a set of XML methods to be exposed to all applications rather than a set of trusted applications. This could allow arbitrary code execution on the vulnerable system in the security context of the currently logged in user.

Technologies Affected

  • Microsoft Virtual Machine 2000 Series
  • Microsoft Virtual Machine 3000 Series
  • Microsoft Virtual Machine 3100 Series
  • Microsoft Virtual Machine 3188
  • Microsoft Virtual Machine 3200 Series
  • Microsoft Virtual Machine 3300 Series
  • Microsoft Virtual Machine 3802 Series
  • Microsoft Virtual Machine 3805 Series

Recommendations

Run all software as a nonprivileged user with minimal access rights.

Code execution will occur in the security context of the current user. Giving users the lowest possible perivilege level will limit the damage that could be done by executing the code.

Do not follow links provided by unknown or untrusted sources.

Do not view unknown websites with a browser that hosts the vulnerable software.

Do not accept communications that originate from unknown or untrusted sources.

This vulnerability could be exploited by viewing HTML email with a viewer that hosts the vulnerable software. Do not accept HTML email from unkown users.
Microsoft has released patches through the Windows Update website.
