1) Improper access control

EUVDB-ID: #VU21964

Risk: Medium

CVSSv4.0: 7.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Green]

CVE-ID: CVE-2019-17574

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to calls which can be performed and require no authentication. A remote attacker can call any method which contains an action starting from "popmake_" or "pum_", execute functions which do not require arguments (e.g: PUM_Admin_Tools::sysinfo_download or PUM_Admin_Tools::sysinfo_display) and obtain information regarding WordPress Plugins (active/inactive), the Webserver Configuration, the PHP Configuration and more.

PoC:

  1. curl http://www.your-domain-with-popup-maker.com/?pum_action=tools_page_tab_system_info
  2. curl -v -d “popmake_action=popup_sysinfo&popmake-sysinfo=choose any content you like” -X POST http://www.your-domain-with-popup-maker.com/
