The following table presents a summary of the 2013 Top 10 Application Security Risks, and the risk factors we have assigned to each risk. These factors were determined based on the available statistics and the experience of the OWASP Top 10 team. To understand these risks for a particular application or organization, <u>you must consider your own specific threat agents and business impacts</u>. Even egregious software weaknesses may not present a serious risk if there are no threat agents in a position to perform the necessary attack or the business impact is negligible for the assets involved.

2013 Top 10 List

 
Top 10 Risk Factor Summary

The following table presents a summary of the 2013 Top 10 Application Security Risks, and the risk factors we have assigned to each risk. These factors were determined based on the available statistics and the experience of the OWASP Top 10 team. To understand these risks for a particular application or organization, you must consider your own specific threat agents and business impacts. Even egregious software weaknesses may not present a serious risk if there are no threat agents in a position to perform the necessary attack or the business impact is negligible for the assets involved.


Risk Threat Agents Attack Vectors Security Weakness

Technical Impacts Business Impacts
A1-Injection App Specific EASY COMMON AVERAGE SEVERE App Specific
A2-Authentication App Specific AVERAGE WIDESPREAD AVERAGE SEVERE App Specific
A3-XSS App Specific AVERAGE VERY WIDESPREAD EASY MODERATE App Specific
A4-Insecure DORApp Specific EASY COMMON EASY MODERATE App Specific
A5-Misconfig App Specific EASY COMMON EASY MODERATE App Specific
A6-Sens. Data App Specific DIFFICULT UNCOMMON AVERAGE SEVERE App Specific
A7-Function Acc. App Specific EASY COMMON AVERAGE MODERATE App Specific
A8-CSRF App Specific AVERAGE COMMON EASY MODERATE App Specific
A9-vuln. Components App Specific AVERAGE WIDESPREAD DIFFICULT MODERATE App Specific
A10-unval. Redirects App Specific AVERAGE UNCOMMON EASY MODERATE App Specific


Additional Risks to Consider

The Top 10 cover a lot of ground, but there are many other risks you should consider and evaluate in your organization. Some of these have appeared in previous versions of the Top 10, and others have not, including new attack techniques that are being identified all the time. Other important application security risks (in alphabetical order) that you should also consider include:
