Sites: Summary of Vulnerabilities WhiteHat Security - Security Audit Report Page 5 of 12 Appendix - Vulnerability Level Definitions (by Risk) Risk Levels for the WhiteHat Sentinel Source solution are based on the OWASP risk rating methodology, which is summarized below. The methodology is essentially based on the standard risk model (Risk = Likelihood x Impact) with several factors contributing to the likelihood and impact. The likelihood can be broken down into Threat Agent Factors and Vulnerability Factors. By analyzing the threat agent, we estimate the likelihood of a successful attack. By analyzing the vulnerability factors, we estimate the likelihood of the vulnerability being discovered and exploited. Because there are so many possible threat agents and factors involved, the worst case scenario is used when determining likelihood. Factors that influence the threat agent include: skill level, motive, opportunity, and size of the threat. Factors that influence the vulnerability include: easy of discovery, ease of exploit, awareness, and intrusion detection. The Impact can be broken down into the Technical Impact and Business Impact. Technical impact considers the traditional areas of security: confidentiality, integrity, availability, and accountability. The business impact stems from the technical impact and consider things such as: financial damage, reputational damage, non-compliance, and privacy violations. High Medium Low 6-9 3-5 0-2 After scoring the Likelihood and Impact, the Risk Rating is determined using the following table: Impact Likelihood Low Medium High High Medium High Critical Medium Low Medium High Low Note or Low Low Medium Risk ratings are defined below: Rating Description Critical A vulnerability that could have a catastrophic impact if the attack succeeds, and the vulnerability is easy to identify and exploit. The vulnerability likely affects all or many users. The vulnerability poses an immediately danger and should be mitigated immediately - In some cases, the application should even be taken offline. High A vulnerability that is likely to have a significant impact if the attack succeeds and the vulnerability is fairly easy to identify and exploit. The vulnerability may affect more than one user. The vulnerability should be mitigated as soon as possible. Medium A vulnerability that is likely to have a moderate to significant impact if the attack succeeds, but may be difficult to identify or exploit or only affects a small number of users. The vulnerability should be mitigated relatively soon. Low A vulnerability that is likely to have a low to moderate impact if the attack succeeds, but is difficult to identify or exploit, or only affects a small number of users. The vulnerability should be mitigated if there is time and whenever it is convenient (e.g. next release) Note A finding that does not pose any risk for the application and does not need to be fixed. However, it is something that should be considered to further improve security from an already acceptable level WhiteHat Security - Security Audit Report Page 6 of 12 Appendix - Assessment Methodology for Dynamic Analysis WhiteHat Security combines a proprietary vulnerability scanning engine with human intelligence and analysis from its Threat Research Center to deliver thorough and accurate assessments of web applications with its Sentinel Service.

WhiteHat Security - Security Audit Report Page 7 of 12 Sentinel Premium Edition Testing Checklist Sentinel Premium Edition service level tests for the following list of WASC classes of Web vulnerabilities: Authentication Tests 1. Brute Force A Brute Force attack is an automated process of trial and error used to guess a person's username, password, credit-card number or cryptographic key. 2. Insufficient Authentication Insufficient Authentication occurs when a web site permits an attacker to access sensitive content or functionality without having to properly authenticate. 3. Weak Password Recovery Validation Weak Password Recovery Validation is when a web site permits an attacker to illegally obtain, change or recover another user's password. 4. Cross-site Request Forgery Cross-site Request Forgery is a type of attack whereby unauthorized commands are transmitted from a user that the website trusts. 5. Credential/Session Prediction Credential/Session Prediction is a method of hijacking or impersonating a web site user. 6. Insufficient Authorization Insufficient Authorization is when a web site permits access to sensitive content or functionality that should require increased access control restrictions. 7. Insufficient Session Expiration Insufficient Session Expiration is when a web site permits an attacker to reuse old session credentials or session IDs for authorization. 8. Session Fixation Session Fixation is an attack technique that forces a user's session ID to an explicit value. Client-side Attack Tests 9. Content Spoofing Content Spoofing is an attack technique used to trick a user into believing that certain content appearing on a web site is legitimate and not from an external source. 10. Cross-site Scripting Cross-site Scripting (XSS) is an attack technique that forces a web site to echo attacker-supplied executable code, which loads in a user's browser. 11. HTTP Response Splitting HTTP Response Splitting is a technique allowing the attacker to send a single HTTP request that forces the Web server to send two HTTP responses instead of one response, in the normal case. The attacker completely controls the second response. WhiteHat Security - Security Audit Report Page 8 of 12 Command Execution Tests 12. Buffer Overflow Buffer Overflow exploits are attacks that alter the flow of an application by overwriting parts of memory. 13. Format String Attack Format String Attacks alter the flow of an application by using string formatting library features to access other memory space. 14. LDAP Injection LDAP Injection is an attack technique used to exploit web sites that construct LDAP statements from user-supplied input. 15. OS Commanding OS Commanding is an attack technique used to exploit web sites by executing Operating System commands through manipulation of application input. 16. SQL Injection SQL Injection is an attack technique used to exploit web sites that construct SQL statements from user-supplied input. 17. SSI Injection SSI Injection (Server-side Include) is a server-side exploit technique that allows an attacker to send code into a web application, which will later be executed locally by the web server. 18. XPath Injection XPath Injection is an attack technique used to exploit web sites that construct XPath queries from user-supplied input. Information Disclosure Tests 19. Directory Indexing Automatic directory listing/indexing is a web server function that lists all of the files within a requested directory if the normal base file is not present. 20. Information Leakage Information Leakage is when a web site reveals sensitive data, such as developer comments or error messages, which may aid an attacker in exploiting the system. 21. Path Traversal The Path Traversal attack technique forces access to files, directories, and commands that potentially reside outside the web document root directory. 22. Predictable Resource Location Predictable Resource Location is an attack technique used to uncover hidden web site content and functionality. WhiteHat Security - Security Audit Report Page 9 of 12 Logical Attack Tests 23. Abuse of Functionality Abuse of Functionality is an attack technique that uses a web site's own features and functionality to consume, defraud, or circumvents access controls mechanisms. 24. Denial of Service Denial of Service (DoS) is an attack technique with the intent of preventing a web site from serving normal user activity. 25. Insufficient Anti-automation Insufficient Anti-automation is when a web site permits an attacker to automate a process that should only be performed manually. 26. Insufficient Process validation Insufficient Process Validation is when a web site permits an attacker to bypass or circumvent the intended flow control of an application.
