Become a Security Rockstar with ColdFusion 2016
This document provides an overview of how to improve security when using ColdFusion 2016. It discusses installing ColdFusion with the secure profile, following the lockdown guide, applying updates, and using the new Security Analyzer tool. The Security Analyzer checks code for vulnerabilities like SQL injection, XSS, and CSRF. The document also recommends coding practices to avoid vulnerabilities, such as using ESAPI encoders and <cfqueryparam>. Proper session management and preventing attacks like XSS, SQL injection, and CSRF are also discussed.

- 22. Cross Site Scripting(XSS) • Enables attackers to inject client-side script into web pages • Session Hijacking • Phishing for passwords or other info • Several types • Persistent (Stored) • Non-Persistent (Reflected) • DOM-based
- 23. Cross Site Scripting(XSS)
- 24. Cross Site Scripting(XSS) • Old encoding functions Context Example HTML <p>Hi #htmlEditFormat(url.name)#</p> HTML Attribute <div id="#htmlEditFormat(url.name)#" /> JavaScript <script>x='#jsStringFormat(url.name)#’</script> <a onmouseover=“foo(#jsStringFormat(url.name)#)"/> CSS <div style="font-family: #form.fontname#" /> URL <a href=“index.cfm?id=#urlEncodedFormat(cookie.id)#" />
- 25. Cross Site Scripting(XSS) • New OWASP ESAPI encoders available in ColdFusion 10+ • Replace htmlEditFormat, jsStringFormat, and urlEncodedFormat Context Example HTML <p>Hi #encodeForHTML(url.name)#</p> HTML Attribute <div id="#encodeForHTMLAttribute(url.name)#" /> JavaScript <script>x=’#encodeForJavascript(url.name)#’</script> <a onmouseover=“foo(#encodeForJavaScript(url.name)#)"/> CSS <div style="font-family: #encodeForCSS(form.fontname)#" /> URL <a href=“index.cfm?id=#encodeForURL(cookie.id)#" />

- 29. SQL Injection • Allows attacker to do any of the following: •Download all data in database • Modify or Delete all data in database • Execute stored procedures or processes in some cases
- 30.
- 31. SQL Injection –Partially Fixed • <cfqueryparam> was introduced in ColdFusion 4.5 • Still missing in a lot of old code and too many developers do not use it
- 32. SQL Injection –Fixed
- 33. SQL Injection • SQL Injection is not limited to <cfquery> •Stored procedures • Use <cfprocparam> • Do not use exec inside <cfquery> • ORMExecuteQuery() and QueryExecute()
- 34. Cross-site Request Forgery •Causes a user’s web browser to perform an unwanted action on a trusted site for which the user is currently authenticated • Could result in a transfer of funds, changing a password, or purchasing an item • Impact vary greatly based on the privileges of the user • Occurs without knowledge of the target user, until the unauthorized transaction has been committed
- 35. Cross-site Request Forgery •Random Token • CSRFGenerateToken([key], [forceNew]) • Generates a random token and stores it in the session • CSRFVerifyToken(token, [key]) • Validates the passed in token against the token stored in the session • Must have session variables enabled
- 36. Session Management • SessionRotate() •Creates a new session and copies session scope into this new session, then invalidates the old session • Used after a valid login to prevent session fixation • SessionInvalidate() • Clears session scope and makes the current session identifiers no longer valid • Only works with ColdFusion sessions (CFID/CFToken), does not work with JEE sessions (JSESSIONID) • SessionRotate for JEE sessions - http://www.petefreitag.com/item/829.cfm

- 38. Security Analyzer Commandline •Adobe only built access to Security Analyzer through ColdFusion Builder But… • Using new commandline abilities in ColdFusion 2016 built a solution • Available on GitHub, https://github.com/dcepler/cf-cmdline-sec-ana • Requires ColdFusion Server 2016 Update 2 or higher • Allows for integration of the Security Analyzer into source code commit hooks and build processes
