Wings is the server control plane for Pterodactyl, a free, open-source game server management panel. Prior to version 1.12.1, a missing authorization check in multiple controllers allows any user with access to a node secret token to fetch information about any server on a Pterodactyl instance, even if that server is associated with a different node. This issue stems from missing logic to verify that the node requesting server data is the same node that the server is associated with. Any authenticated Wings node can retrieve server installation scripts (potentially containing secret values) and manipulate the installation status of servers belonging to other nodes. Wings nodes may also manipulate the transfer status of servers belonging to other nodes. This vulnerability requires a user to acquire a secret access token for a node. Unless a user gains access to a Wings secret access token they would not be able to access any of these vulnerable endpoints, as every endpoint requires a valid node access token. A single compromised Wings node daemon token (stored in plaintext at `/etc/pterodactyl/config.yml`) grants access to sensitive configuration data of every server on the panel, rather than only to servers that the node has access to. An attacker can use this information to move laterally through the system, send excessive notifications, destroy server data on other nodes, and otherwise exfiltrate secrets that they should not have access to with only a node token. Additionally, triggering a false transfer success causes the panel to delete the server from the source node, resulting in permanent data loss. Users should upgrade to version 1.12.1 to receive a fix.

Pterodactyl is a free, open-source game server management panel. Pterodactyl implements rate limits that are applied to the total number of resources (e.g. databases, port allocations, or backups) that can exist for an individual server. These resource limits are applied on a per-server basis, and validated during the request cycle. However, in versions prior to 1.12.0, it is possible for a malicious user to send a massive volume of requests at the same time that would create more resources than the server is allotted. This is because the validation occurs early in the request cycle and does not lock the target resource while it is processing. As a result sending a large volume of requests at the same time would lead all of those requests to validate as not using any of the target resources, and then all creating the resources at the same time. As a result a server would be able to create more databases, allocations, or backups than configured. A malicious user is able to deny resources to other users on the system, and may be able to excessively consume the limited allocations for a node, or fill up backup space faster than is allowed by the system. Version 1.12.0 fixes the issue.

Importing a malicious egg or gaining access to wings instance could lead to cross site scripting (XSS) on the panel, which could be used to gain an administrator account on the panel. Specifically, the following things are impacted: Egg Docker images and Egg variables: Name, Environment variable, Default value, Description, Validation rules. Additionally, certain fields would reflect malicious input, but it would require the user knowingly entering such input to have an impact. To iterate, this would require an administrator to perform actions and can't be triggered by a normal panel user. This issue has has been addressed in version 1.11.6 and users are advised to upgrade. No workaround is available other than updating to the latest version of the panel.

At no point would any data be exposed to the malicious user, this would simply trigger email spam to an administrative user, or generate a single auto-deployment token unexpectedly. This token is not revealed to the malicious user, it is simply created unexpectedly in the system. This has been addressed in release `1.6.6`. Users may optionally manually apply the fixes released in v1.6.6 to patch their own systems.

Pterodactyl is an open-source game server management panel built with PHP 7, React, and Go. A malicious user can modify the contents of a `confirmation_token` input during the two-factor authentication process to reference a cache value not associated with the login attempt. In rare cases this can allow a malicious actor to authenticate as a random user in the Panel. The malicious user must target an account with two-factor authentication enabled, and then must provide a correct two-factor authentication token before being authenticated as that user. Due to a validation flaw in the logic handling user authentication during the two-factor authentication process a malicious user can trick the system into loading credentials for an arbitrary user by modifying the token sent to the server. This authentication flaw is present in the `LoginCheckpointController@__invoke` method which handles two-factor authentication for a user. This controller looks for a request input parameter called `confirmation_token` which is expected to be a 64 character random alpha-numeric string that references a value within the Panel's cache containing a `user_id` value. This value is then used to fetch the user that attempted to login, and lookup their two-factor authentication token. Due to the design of this system, any element in the cache that contains only digits could be referenced by a malicious user, and whatever value is stored at that position would be used as the `user_id`. There are a few different areas of the Panel that store values into the cache that are integers, and a user who determines what those cache keys are could pass one of those keys which would cause this code pathway to reference an arbitrary user. At its heart this is a high-risk login bypass vulnerability. However, there are a few additional conditions that must be met in order for this to be successfully executed, notably: 1.) The account referenced by the malicious cache key must have two-factor authentication enabled. An account without two-factor authentication would cause an exception to be triggered by the authentication logic, thusly exiting this authentication flow. 2.) Even if the malicious user is able to reference a valid cache key that references a valid user account with two-factor authentication, they must provide a valid two-factor authentication token. However, due to the design of this endpoint once a valid user account is found with two-factor authentication enabled there is no rate-limiting present, thusly allowing an attacker to brute force combinations until successful. This leads to a third condition that must be met: 3.) For the duration of this attack sequence the cache key being referenced must continue to exist with a valid `user_id` value. Depending on the specific key being used for this attack, this value may disappear quickly, or be changed by other random user interactions on the Panel, outside the control of the attacker. In order to mitigate this vulnerability the underlying authentication logic was changed to use an encrypted session store that the user is therefore unable to control the value of. This completely removed the use of a user-controlled value being used. In addition, the code was audited to ensure this type of vulnerability is not present elsewhere.
