Rapid7 AppSpider vulnerabilities

Recently, I checked out Rapid7's AppSpider Web Application Testing software. It is a Windows based application, and the demo version is available for anyone to play with.

I found 2 vulnerabilities in AppSpider - DLL Pre-loading & Buffer overflow - which I then reported privately to R7 team. The folks at Rapid7 confirmed my reports and released the CVE-ID# & fixed versions shortly after.

Here's the writeup from Rapid7 Release Announcement:

  1. Updated nginx.exe to utilize Microsoft Security Advisory on remote code execution. Windows 7, Windows Server 2008 R2, Windows Vista and Windows Server 2008: KB2533623 must be installed on the target platform. Resolves - CVE-2017-5236
  2. Resolved buffer over flow crash in the AppSpider command line tool for inputs. Resolves - CVE-2017-5240
