CVE-2024-24553 (GCVE-0-2024-24553)

Vulnerability from cvelistv5 – Published: 2024-06-24 07:10 – Updated: 2024-08-01 23:19

Title

Bludit uses SHA1 as Password Hashing Algorithm

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.

Severity
