CVE-2024-0436

Prevent timing attack for single-user password check

High7.1EPSS 0.48%
Published
Updated
Reserved
Assigned by
@huntr_ai

Description

Theoretically, it would be possible for an attacker to brute-force the password for an instance in single-user password protection mode via a timing attack given the linear nature of the `!==` used for comparison. The risk is minified by the additional overhead of the request, which varies in a non-constant nature making the attack less reliable to execute
