• Patching – ColdFusion requires manual patching, unzip in folder, overwrite a jar, etc – Admin interface doesn’t alert you to available patches – I’

• Pro Tip • Determining version is helpful for insta-shell exploits • Metasploit module can tell you by admin interface, or you can just look at CFIDE

• Or you can check the wsdl  • /CFIDE/adminapi/base.cfc?wsdl – Checked on 7-9 Attacking ColdFusion

Attacking ColdFusion • Yeah, CF 8 too (has patch)

• Admin Interfaces • /CFIDE/administrator/index.cfm salts the password Attacking ColdFusion

• Lots of other pages don’t  • Ex. /CFIDE/componentutils/login.cfm Attacking ColdFusion

• Get the password right, CF sets a cookie Attacking ColdFusion

• Metasploit Module • Can do this easily in Burp Suite as well Attacking ColdFusion

Your passwords suck

• But real world? Attacking ColdFusion

• From 2009 to 2012… Attacking ColdFusion

• ColdFusion Privilege Level • Scheduling tasks • Executing code • Decrypting database credentials • CFM Shells Post Exploitation

• ColdFusion (by default) runs as SYSTEM on Windows and NOBODY ON *nix • Obviously, CF on Windows is what you want • Sites that run other languages t

• Scheduling Tasks • Once you have access to admin interface you can schedule a task to download code/executables/ bat files/etc Post Exploitation

Post Exploitation

• Executing code • Once you have code/exe on box you can create a system probe (that we want to fail) to make the code execute • Or if you put cfm/jsp

• CFM Shells • ColdFusion has several handy CFML tags: – CFEXECUTE – CFREGISTRY – CFFILE – CFHTTP Simple CFM Shell: <html> <body> <cfe

• CFM Shells • Its common to disable CFEXECUTE* • CF also runs java so: <cfset runtime = createObject("java", "java.lang.System"

• CFM Shells • Remember Enterprise vs Standard? – Enterprise runs jsp, so some jsp shells will work too (depends on the shell’s java version requireme
