CVE-2023-2764 (GCVE-0-2023-2764)

Vulnerability from cvelistv5 – Published: 2023-06-09 05:33 – Updated: 2026-04-08 16:37
VLAI
Title
Draw Attention <= 2.0.11 - Missing Authorization to Arbitrary Post Featured Image Modification
Summary
The Draw Attention plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the ajax_set_featured_image function in versions up to, and including, 2.0.11. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to change the featured image of arbitrary posts with an image that exists in the media library.

CVE-2023-2757 (GCVE-0-2023-2757)

Vulnerability from cvelistv5 – Published: 2023-05-18 02:04 – Updated: 2026-04-08 16:46
VLAI
Title
Waiting: One-click countdowns <= 0.6.2 - Missing Authorization Checks leading to Authenticated (Subscriber+) Stored Cross-Site Scripting
Summary
The Waiting: One-click countdowns plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on 'saveLang' functions in versions up to, and including, 0.6.2. This could lead to Cross-Site Scripting due to insufficient input sanitization and output escaping. This makes it possible for subscriber-level attackers to access functions to save plugin data that can potentially lead to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Title
Groundhogg <= 2.7.9.8 - Missing Authorization to Non-Arbitrary File Upload
Summary
The Groundhogg plugin for WordPress is vulnerable to unauthorized access of data and modification of data due to a missing capability check on the 'ajax_upload_file' function in versions up to, and including, 2.7.9.8. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload a file to the contact, and then lists all the other uploaded files related to the contact.

CVE-2023-2715 (GCVE-0-2023-2715)

Vulnerability from cvelistv5 – Published: 2023-05-20 02:03 – Updated: 2026-04-08 16:42
VLAI
Title
Groundhogg <= 2.7.9.8 - Missing Authorization to Admin Account and Ticket Creation
Summary
The Groundhogg plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'submit_ticket' function in versions up to, and including, 2.7.9.8. This makes it possible for authenticated attackers to create a support ticket that sends the website's data to the plugin developer, and it is also possible to create an admin access with an auto login link that is also sent to the plugin developer with the ticket. It only works if the plugin is activated with a valid license.

CVE-2023-2714 (GCVE-0-2023-2714)

Vulnerability from cvelistv5 – Published: 2023-05-20 02:03 – Updated: 2026-04-08 16:43
VLAI
Title
Groundhogg <= 2.7.9.8 - Missing Authorization to Update License
Summary
The Groundhogg plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'check_license' functions in versions up to, and including, 2.7.9.8. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to change the license key and support license key, but it can only be changed to a valid license key.

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.
