CVE-2015-20110: Jhipster

High severity, CVSS 7.5. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

Affected products

• Jhipster Jhipster: before 2.23.0 (fixed in 2.23.0)
