🔓 Exploitability Engine

Introduction

After the Reachability Engine generates reports about the application’s codebase, it is important to fine-tune more parameters to successfully understand the total security posture of the application’s codebase. The exploitability engine is responsible for understanding the actual possibility of exploiting the vulnerabilities that are found.

Why Calculate Exploitability?

It’s not always the case that a vulnerability is found, it’s can be exploited in any conditions. Publically released exploits often tend to work in ideal conditions but this may not be the case in the given project itself. Hence, after calculating the reachability and severity, it’s important to sort out the ones that are exploitable and the ones that are not exploitable at the current moment. This allows developers to focus on security issues that are highly suspected of being exploited rather than severe ones that cannot be exploited.

Myrror’s Exploitability Engine

Myrror Security holds its expertise in prioritizing vulnerabilities and calculating factors influencing the requirements of urgent remediation change with various parameters. Some issues are highly severe but are unlikely to be exploited if certain conditions are not met. In case that function is unreachable, there would be little of any requirement to fix it before the ones that can be exploited and are reachable, even if its severity was comparatively less.

Myrror Security’s R&D extensively works on vulnerabilities and their impacts on various projects. A finely calibrated database is regularly updated with new data on vulnerabilities which provides users with additional information from experts from Myrror Security.

There are a lot of factors that affect the exploitability of the application. Apart from the statistics and vulnerability research from the R&D of Myrror Security, it also refers to data from the Known Exploited Vulnerabilities Catalog (KEV) as well as the Exploit Prediction Scoring System (EPSS). The KEV is a resource that keeps track of vulnerabilities that have been actively exploited by attackers. It contains information about the vulnerability, affected software or systems, known exploits, mitigations, and patches or fixes provided by vendors. EPSS is a framework used to assess the likelihood of a vulnerability being exploited in the next 30 days. It is designed to help organizations prioritize their patch management efforts by focusing on vulnerabilities that are more likely to be targeted by attackers.

These resources help Myrror acknowledge the publicly researched information paired with its own research on various vulnerabilities that impact projects on a large scale.

Conclusion

The exploitability engine adds an extra layer in fine-tuning the priority list and makes its data more inclined toward practical environments. In the end, the outcome of patching the vulnerabilities in the final build is all that matters, and if done right, allows developers to be fast and efficient in the development process.
