CVSS v3.1

Official Description

An issue was discovered in Z-BlogPHP 2.0.0. zb_system/cmd.php?act=verify relies on MD5 for the password parameter, which might make it easier for attackers to bypass intended access restrictions via a dictionary or rainbow-table attack. NOTE: the vendor declined to accept this as a valid issue

Technical Analysis

CVE-2018-11209 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.2.
