Microsoft Windows Server Service Could Allow Remote Code Execution (MS08-067) and Shadow Brokers (ECLIPSEDWING)
- Urgent 5
- Qualys ID
- Vendor Reference
- CVE Reference
- CVSS Scores
- Base 10 / Temporal 8.3
The Microsoft Windows Server service provides RPC support, file print support and named pipe sharing over the network. The Server service allows the sharing of local resources (such as disks and printers) so that other users on the network can access them. It also allows named pipe communication between applications running on other computers and your computer, which is used for RPC.
The Server service is vulnerable to remote code execution issue, due to the service not properly handling specially-crafted RPC requests. Any anonymous user who can deliver a specially-crafted message to the affected system could try to exploit this vulnerability.

Selective Scan Instructions Using Qualys
To perform a selective vulnerability scan, configure a scan profile to use the following options:
- Ensure access to TCP ports 135 and 139 are available.
- Enable Windows Authentication (specify Authentication Records).
Enable the following Qualys IDs:
- If you would like the scan to return the Windows Hostname, also include QID 82044 and ensure access to UDP port 137 is available.
- If you would like to be notified if Qualys is unable to log on to a host (if Authentication fails), also include QID 105015.
