CVE-2015-20110

Summary

CVE-2015-20110 is a timing attack vulnerability affecting JHipster's generator-jhipster before version 2.23.0. The issue lies in the validation of tokens, which performs a string comparison that halts at the first character that differs. Attackers can exploit this weakness by brute forcing each token character and observing the response time. With this method, the attacker's search space is significantly reduced to the token length multiplied by the possible characters, making the process far less time-consuming and computationally expensive compared to a full brute force attack.
