Active Scan++

ActiveScan++ extends Burp Suite's active and passive scanning capabilities. Designed to add minimal network overhead, it identifies application behaviour that may be of interest to advanced testers:

  • Potential host header attacks (password reset poisoning, cache poisoning, DNS rebinding)
  • Edge side includes
  • XML input handling
  • Suspicious input transformation (eg 7*7 => '49', \x41\x41 => 'AA')
  • Passive-scanner issues that only occur during fuzzing (install the 'Error Message Checks' extension for maximum effectiveness)

It also adds checks for the following issues:

  • Blind code injection via expression language, Ruby's open() and Perl's open()
  • CVE-2014-6271/CVE-2014-6278 'shellshock' and CVE-2015-2080, CVE-2017-5638, CVE-2017-12629, CVE-2018-11776

It also provides insertion points for HTTP basic authentication.

To invoke these checks, just run a normal active scan.

The host header checks tamper with the host header, which may result in requests being routed to different applications on the same host. Exercise caution when running this scanner against applications in a shared hosting environment.

This extension requires Burp Suite Professional version 1.6 or later and Jython 2.5 or later standalone.
