Modified
2024-08-01 23:19
Severity ?
5.9 (Medium) - CVSS:4.0/AV:N/AC:H/AT:P/PR:H/UI:N/VC:L/VI:H/VA:N/SC:N/SI:N/SA:N
Summary
Bludit uses the SHA-1 hashing algorithm to compute password hashes. Thus, attackers could determine cleartext passwords with brute-force attacks due to the inherent speed of SHA-1. In addition, the salt that is computed by Bludit is generated with a non-cryptographically secure function.
