Details

The AffiliateWP for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'affwp_activate_addons_page_plugin' function called via an AJAX action in versions up to, and including, 2.14.0. This makes it possible for authenticated attackers, with subscriber-level access and above, to activate arbitrary plugins.

Summary
Craft CMS has a Missing Authorization Check on User Group Removal via save-permissions Action
Details

Summary

The actionSavePermissions() endpoint allows a user with only viewUsers permission to remove arbitrary users from all user groups. While _saveUserGroups() enforces per-group authorization for additions, it performs no equivalent authorization check for removals, so submitting an empty groups value removes all existing group memberships.

Affected Versions

  • Craft CMS 5.6.0 through 5.9.14 (latest release at time of report)
  • Regression introduced in 5.6.0 when the viewUsers permission was added
  • Prior to 5.6.0, editedUser() required editUsers, which implicitly protected this endpoint
  • Requires Pro edition or higher (the vulnerable code path is gated by CmsEdition::Pro)

Vulnerability Details

Root Cause

This is a regression introduced in Craft CMS 5.6.0 when the viewUsers permission was added. Before that change, editedUser() required editUsers permission for accessing other users’ data, which implicitly protected actionSavePermissions(). After the change, actionSavePermissions() became reachable for users with read-only access to other users, but the underlying group-saving logic still lacked authorization for group removals.

The vulnerability has two components:

  1. actionSavePermissions() reachable with read-only access: The action only requires a control panel request and delegates to editedUser(), which now only checks viewUsers — a permission explicitly documented as "read-only access to user elements."

  2. Asymmetric authorization in _saveUserGroups(): The method checks assignUserGroup permission only when adding a user to a new group. When the groups parameter is an empty string (resulting in an empty array), the loop is skipped entirely, no authorization checks are run, and all group memberships are removed.

Prerequisites

  • Attacker has a control panel account with accessCp and viewUsers permissions only
  • Target user belongs to one or more user groups that grant additional permissions
  • Pro edition or higher

Attack Steps

  1. Attacker authenticates to the Control Panel
  2. Attacker sends a POST request to actions/users/save-permissions with:
  3. userId = target user's ID
  4. groups = `` (empty string)
  5. All group memberships for the target user are removed
  6. All permissions inherited from those groups are immediately revoked

Impact

  • Privilege revocation: An attacker can strip group-based permissions from arbitrary users, including accounts whose effective access derives from group membership
  • Denial of access: Users lose access to sections, volumes, and features that were granted through group membership
  • Bypass of elevated session requirement: Group removal does not trigger requireElevatedSession() (which is only triggered when new groups are added)

Mitigation
Architecture and Design
  • Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
  • Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design

Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].

Mitigation MIT-4.4
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
  • For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
  • One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration Installation

Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.

CAPEC-665: Exploitation of Thunderbolt Protection Flaws

An adversary leverages a firmware weakness within the Thunderbolt protocol, on a computing device to manipulate Thunderbolt controller firmware in order to exploit vulnerabilities in the implementation of authorization and verification schemes within Thunderbolt protection mechanisms. Upon gaining physical access to a target device, the adversary conducts high-level firmware manipulation of the victim Thunderbolt controller SPI (Serial Peripheral Interface) flash, through the use of a SPI Programing device and an external Thunderbolt device, typically as the target device is booting up. If successful, this allows the adversary to modify memory, subvert authentication mechanisms, spoof identities and content, and extract data and memory from the target device. Currently 7 major vulnerabilities exist within Thunderbolt protocol with 9 attack vectors as noted in the Execution Flow.
