Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N
Summary
An issue was discovered in Epikur before 20.1.1. It stores the secret passwords of the users as MD5 hashes in the database. MD5 can be brute-forced efficiently and should not be used for such purposes. Additionally, since no salt is used, rainbow tables can speed up the attack.
