Title
Windmill Labs Windmill - Missing Authorization
Summary
A missing authorization vulnerability in Windmill Labs Windmill through 1.783.0 allows any authenticated workspace member to overwrite any resource type schema via the update_resource_type endpoint. The endpoint omits the administrator permission check that the corresponding delete_resource_type endpoint enforces. An attacker with workspace member privileges can corrupt resource type definitions, breaking workflows that depend on them.

Title
OpenAEV has unauthenticated access and missing object-level authorization on player lessons API
Summary
OpenAEV is an open source platform allowing organizations to plan, schedule and conduct cyber adversary simulation campaign and tests. Prior to version 2.260622.0, on a default installation, the `/api/player/**` lessons endpoints can be called without authentication, and they trust a client-supplied `userId` query parameter without verifying that the caller is that user or a member of the exercise. An unauthenticated client that knows an exercise UUID can read lessons-learned questions and answers (including each answer's author identity) and create or overwrite answers attributed to an arbitrary user. Version 2.260622.0 contains a patch.

Title
KubeVirt backend is not authenticated
Summary
FakeFish handles incoming credentials by passing them down
to scripts. This works for real hardware because in the end it's up to
the BMC to validate them. However, KubeVirt relies on a KUBECONFIG file
mounted to the container and completely ignores the credentials. This allows any user of the cluster to control VMs of the
user that created fakefish, power them on and off, and mount arbitrary CD
images to them.

Title
Nuxt.js Unauthenticated WebSocket RPC Call Leading to Remote Code Execution
Summary
Nuxt is an open-source web development framework for Vue.js. Prior to 3.3.1, Nuxt DevTools (development mode only) exposes a bidirectional RPC channel over the Vite HMR WebSocket via the nuxt:devtools:rpc plugin. On affected versions the channel has no authentication: any client that can reach the Vite HMR endpoint (ws://<host>:<port>/, subprotocol vite-hmr) can call RPC methods, with no token, handshake, or origin check before the channel is established. The updateOptions(), clearOptions(), and openInEditor() methods do not enforce the ensureDevAuthToken check that the other mutating methods use. openInEditor() reads the persisted behavior.openInEditor value and passes it to the launch-editor package, which spawns it as a child process. That value is settable through the equally unauthenticated updateOptions(). An attacker who can reach the HMR port can therefore chain updateOptions('behavior', { openInEditor: '<command>' }) then openInEditor('<any-existing-file>') to execute an arbitrary program on the developer's machine. This issue is fixed in 3.3.1.

Title
Maestro: maestro: rest api write endpoints registered without authentication middleware
Summary
A flaw was found in Maestro. Its REST API write endpoints were registered without proper authentication middleware. This allows a remote attacker to perform unauthorized write operations, such as creating, modifying, or deleting consumers and resource bundles. This could lead to data integrity issues or a denial of service (DoS).

Disabling the route may impact functionality that relies on external access to Maestro\u0027s REST API."

Mitigation
Architecture and Design
- Divide the software into anonymous, normal, privileged, and administrative areas. Identify which of these areas require a proven user identity, and use a centralized authentication capability.
- Identify all potential communication channels, or other means of interaction with the software, to ensure that all channels are appropriately protected, including those channels that are assumed to be accessible only by authorized parties. Developers sometimes perform authentication at the primary channel, but open up a secondary channel that is assumed to be private. For example, a login mechanism may be listening on one network port, but after successful authentication, it may open up a second port where it waits for the connection, but avoids authentication because it assumes that only the authenticated party will connect to the port.
- In general, if the software or protocol allows a single session or user state to persist across multiple connections or channels, authentication and appropriate credential management need to be used throughout.
Mitigation MIT-15
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
Mitigation
Architecture and Design
- Where possible, avoid implementing custom, "grow-your-own" authentication routines and consider using authentication capabilities as provided by the surrounding framework, operating system, or environment. These capabilities may avoid common weaknesses that are unique to authentication; support automatic auditing and tracking; and make it easier to provide a clear separation between authentication tasks and authorization tasks.
- In environments such as the World Wide Web, the line between authentication and authorization is sometimes blurred. If custom authentication routines are required instead of those provided by the server, then these routines must be applied to every single page, since these pages could be requested directly.
Mitigation MIT-4.5
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 libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator [REF-45].
Mitigation
Implementation
System Configuration
Operation
When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to require strong authentication for users who should be allowed to access the data [REF-1297] [REF-1298] [REF-1302].
CAPEC-12: Choosing Message Identifier
This pattern of attack is defined by the selection of messages distributed via multicast or public information channels that are intended for another client by determining the parameter value assigned to that client. This attack allows the adversary to gain access to potentially privileged information, and to possibly perpetrate other attacks through the distribution means by impersonation. If the channel/message being manipulated is an input rather than output mechanism for the system, (such as a command bus), this style of attack could be used to change the adversary's identifier to more a privileged one.
CAPEC-166: Force the System to Reset Values
An attacker forces the target into a previous state in order to leverage potential weaknesses in the target dependent upon a prior configuration or state-dependent factors. Even in cases where an attacker may not be able to directly control the configuration of the targeted application, they may be able to reset the configuration to a prior state since many applications implement reset functions.
CAPEC-216: Communication Channel Manipulation
An adversary manipulates a setting or parameter on communications channel in order to compromise its security. This can result in information exposure, insertion/removal of information from the communications stream, and/or potentially system compromise.
CAPEC-36: Using Unpublished Interfaces or Functionality
An adversary searches for and invokes interfaces or functionality that the target system designers did not intend to be publicly available. If interfaces fail to authenticate requests, the attacker may be able to invoke functionality they are not authorized for.
CAPEC-62: Cross Site Request Forgery
An attacker crafts malicious web links and distributes them (via web pages, email, etc.), typically in a targeted manner, hoping to induce users to click on the link and execute the malicious action against some third-party application. If successful, the action embedded in the malicious link will be processed and accepted by the targeted application with the users' privilege level. This type of attack leverages the persistence and implicit trust placed in user session cookies by many web applications today. In such an architecture, once the user authenticates to an application and a session cookie is created on the user's system, all following transactions for that session are authenticated using that cookie including potential actions initiated by an attacker and simply "riding" the existing session cookie.
