Positive Technologies (AI Summary)

CVSS v3.1

9.8

Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions phpList version 3.5.0

Description The issue allows for admin login bypass due to type juggling. This occurs because the code uses == for password hash comparison instead of ===, which can mishandle hashes starting with 0e followed by numerical characters.

Recommendations For phpList version 3.5.0, consider updating to a newer version that uses === for password hash comparison to prevent type juggling attacks. As a temporary workaround, consider hardening the authentication mechanism to prevent bypass attacks.
