CVE-2020-36666 | Multiple e-plugins - Subscriber+ Privilege Escalation

Exp

The directory-pro WordPress plugin before 1.9.5, final-user-wp-frontend-user-profiles WordPress plugin before 1.2.2, producer-retailer WordPress plugin through TODO, photographer-directory WordPress plugin before 1.0.9, real-estate-pro WordPress plugin before 1.7.1, institutions-directory WordPress plugin before 1.3.1, lawyer-directory WordPress plugin before 1.2.9, doctor-listing WordPress plugin before 1.3.6, Hotel Listing WordPress plugin before 1.3.7, fitness-trainer WordPress plugin before 1.4.1, wp-membership WordPress plugin before 1.5.7, sold by the same developer (e-plugins), do not implementing any security measures in some AJAX calls. For example in the file plugin.php, the function iv_directories_update_profile_setting() uses update_user_meta with any data provided by the ajax call, which can be used to give the logged in user admin capabilities. Since the plugins allow user registration via a custom form (even if the blog does not allow users to register) it makes any site using it vulnerable.

8.8 3.1 HIGH
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H Click to expand
Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
