MS15-034 HTTP Protocol Stack Request Handling Denial-of-Service
This module will check if scanned hosts are vulnerable to CVE-2015-1635 (MS15-034), a vulnerability in the HTTP protocol stack (HTTP.sys) that could result in arbitrary code execution. This module will try to cause a denial-of-service.
Module type : auxiliary Rank : normal
MS15-034 HTTP Protocol Stack Request Handling HTTP.SYS Memory Information Disclosure
This module dumps memory contents using a crafted Range header and affects only Windows 8.1, Server 2012, and Server 2012R2. Note that if the target is running in VMware Workstation, this module has a high likelihood of resulting in BSOD; however, VMware ESX and non-virtualized hosts seem stable. Using a larger target file should result in more memory being dumped, and SSL seems to produce more data as well.
