Title
XWiki provides no warning when granting XWiki.Notifications.Code.NotificationEmailRendererClass admin right
Summary
XWiki is a generic wiki platform. When a user without script right creates a document with an `XWiki.Notifications.Code.NotificationEmailRendererClass` object, and later an admin edits and saves that document, the email templates in this object will be used for notifications. No malicious code can be executed, though, as while these templates allow Velocity code, the existing generic analyzer already warns admins before editing Velocity code. The main impact would thus be to send spam, e.g., with phishing links to other users or to hide notifications about other attacks. Note that warnings before editing documents with dangerous properties have only been introduced in XWiki 15.9, before that version, this was a known issue and the advice was simply to be careful. This has been patched in XWiki 16.10.2, 16.4.7 and 15.10.16 by adding an analysis for the respective XClass properties.

Title
FreePBX API has a Privilege Escalation Error in GraphQL Allowing Authenticated Users to Access Additional Scopes
Summary
FreePBX is an open-source web-based graphical user interface (GUI) that manages Asterisk. Prior to 17.0.5 and 16.0.17, FreePBX module api (PBX API) is vulnerable to privilege escalation by authenticated users with REST/GraphQL API access. This vulnerability allows an attacker to forge a valid JWT with full access to the REST and GraphQL APIs on a FreePBX that they've already connected to, possibly as a lower privileged user. The JWT is signed using the api-oauth.key private key. An attacker can generate their own token if they possess this key (e.g., by accessing an affected instance), and specify any scopes they wish (e.g., rest, gql), bypassing traditional authorization checks. However, FreePBX enforces that the jti (JWT ID) claim must exist in the database (api_access_tokens table in the asterisk MySQL database) in order for the token to be accepted. Therefore, the attacker must know a jti value that already exists on the target instance. This vulnerability is fixed in 17.0.5 and 16.0.17.

Mitigation ID: MIT-1
Phases: Architecture and Design, Operation
Description:
- Very carefully manage the setting, management, and handling of privileges. Explicitly manage trust zones in the software.
Mitigation ID: MIT-17
Phases: Architecture and Design, Operation
Strategy: Environment Hardening
Description:
- Run your code using the lowest privileges that are required to accomplish the necessary tasks [REF-76]. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
Mitigation ID: MIT-49
Phase: Architecture and Design
Strategy: Separation of Privilege
Description:
- Consider following the principle of separation of privilege. Require multiple conditions to be met before permitting access to a system resource.
CAPEC-17: Using Malicious Files
An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
CAPEC-30: Hijacking a Privileged Thread of Execution
An adversary hijacks a privileged thread of execution by injecting malicious code into a running process. By using a privleged thread to do their bidding, adversaries can evade process-based detection that would stop an attack that creates a new process. This can lead to an adversary gaining access to the process's memory and can also enable elevated privileges. The most common way to perform this attack is by suspending an existing thread and manipulating its memory.
CAPEC-35: Leverage Executable Code in Non-Executable Files
An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
