Title
MISP OnDemand Correlation Engine Missing Access Control Allows Disclosure of Restricted Correlations
Summary
MISP contains an authorization flaw in the OnDemand correlation engine where correlations were calculated solely from matching attribute values without applying the distribution, sharing group, organization, or other access-control restrictions associated with the correlated attributes and events. As a result, an authenticated user could receive correlation results referring to attributes or events that the user was not authorized to access.
The vulnerable correlation collection path did not take the requesting user into account. The patch changes the correlation collector to accept the current user and filters the resulting attribute identifiers through MISP's existing fetchAttributesSimple() authorization logic, which evaluates event-, attribute-, object-, distribution-, and sharing-group-level restrictions against the live data.
The issue also affected paths relying on previously stored correlation data. Because the OnDemand engine does not maintain the stored correlation table, its denormalized access-control information could be stale. The patch therefore validates correlated attribute identifiers against the current ACLs before returning them and additionally applies normal event visibility conditions when retrieving related events.
An authenticated low-privileged user could exploit this issue by querying or creating attributes that correlate with restricted MISP content, potentially learning information about otherwise inaccessible events or attributes.

Kill Bill through 0.24.21 Missing Authorization on AdminResource Endpoints
Summary
Kill Bill through 0.24.21 fails to enforce permission annotations on several AdminResource endpoints including getQueueEntries, invalidatesCache, and putOutOfRotation. Authenticated users with minimal account:read permissions can read internal queues, flush server caches, and disable the server by putting the host out of rotation.

Oppia through 3.5.2 Missing Authorization on AdminRoleHandler GET
Summary
Oppia's AdminRoleHandler GET endpoint in core/controllers/admin.py is decorated with open_access, allowing any registered user to enumerate privileged accounts and roles. Attackers can query the endpoint with filter_criterion parameters to retrieve usernames holding specific roles, banned flags, and managed topic identifiers without authorization.

Title
ntopng's Missing Authorization in REST API Allows Non-Admin Users to Delete and Rename Arbitrary Tags
Summary
ntopng is a web-based network traffic monitoring application. In versions 6.7.0 through 6.7.260717, two REST v2 endpoints that manage ntopng's tag/badge feature — `POST /lua/rest/v2/delete/tag/tag.lua` and `POST /lua/rest/v2/edit/tag/tag.lua` — perform no authorization check at all. Any authenticated user, including a non-administrator ("unprivileged") account, can delete or rename any tag in the system, including tags created by an administrator. Version 6.7.260718 contains a fix.

WPFunnels <= 3.12.13 - Missing Authorization to Unauthenticated Arbitrary Product Price Manipulation via 'wpfnl_load_payment' AJAX Action
Summary
The WPFunnels plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 3.12.13. This is due to the plugin registering the 'wpfnl_load_payment' AJAX action for both authenticated and unauthenticated (wp_ajax_nopriv_) users and the underlying add_offer_product_to_cart() function performing no nonce verification, no capability check, and no validation that the attacker-supplied product_id is the offer product actually configured on the attacker-supplied step_id. This makes it possible for unauthenticated attackers to add arbitrary WooCommerce products to a cart at any discounted price configured on any funnel step, enabling price manipulation and revenue loss at checkout.

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.
