GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

FKIE_CVE-2024-24553

Vulnerability from fkie_nvd - Published: 2024-06-24 07:15 - Updated: 2026-06-17 07:14
Severity
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A: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.
