Description
JHipster generator-jhipster before 2.23.0 allows a timing attack against validateToken due to a string comparison that stops at the first character that is different. Attackers can guess tokens by brute forcing one character at a time and observing the timing. This of course drastically reduces the search space to a linear amount of guesses based on the token length times the possible characters.
CWEs
- CWE-208 · Observable Timing Discrepancy
- CWE-307 · Improper Restriction of Excessive Authentication Attempts
