OWASP Proposes New Vulnerabilities for 2017 Top 10

The Open Web Application Security Project (OWASP) announced on Monday the first release candidate for the 2017 OWASP Top 10, which proposes two new vulnerability categories.

The new categories proposed for OWASP Top 10 - 2017 are “insufficient attack detection and prevention” and “unprotected APIs.”

OWASP wants to make room for the “unprotected APIs” category by dropping “unvalidated redirects and forwards,” the 10th item on the current (2013) list, which was added to the top 10 in 2010.

The new insufficient attack protection category would be added to the 7th position. OWASP wants to make room for it by merging the current 4th and 7th items, namely insecure direct object references with missing function level access control. The organization has proposed the merger of the two old categories into “broken access control”, as it was back in 2004.

OWASP has provided the following description for the insufficient attack protection category: “The majority of applications and APIs lack the basic ability to detect, prevent, and respond to both manual and automated attacks. Attack protection goes far beyond basic input validation and involves automatically detecting, logging, responding, and even blocking exploit attempts. Application owners also need to be able to deploy patches quickly to protect against attacks.”

In a discussion on Reddit, several users said “insufficient attack protection” should not be classified as a flaw. It remains to be seen if enough users agree to make OWASP change its mind about creating a new category for it.

As for the unprotected APIs category, OWASP says, “Modern applications often involve rich client applications and APIs, such as JavaScript in the browser and mobile apps, that connect to an API of some kind (SOAP/XML, REST/JSON, RPC, GWT, etc.). These APIs are often unprotected and contain numerous vulnerabilities.”

Comments on the 2017 Top 10 proposal can be submitted via email until June 30 to OWASP-TopTen(at), or dave.wichers(at) (for private comments). The final version will be released in either July or August.
