Mintplexlabs: >> Anythingllm Security Vulnerabilities
A Denial of Service (DoS) vulnerability exists in the mintplex-labs/anything-llm repository when the application is running in 'just me' mode with a password. An attacker can exploit this vulnerability by making a request to the endpoint using the [validatedRequest] middleware with a specially crafted 'Authorization:' header. This vulnerability leads to uncontrolled resource consumption, causing a DoS condition.

A stored Cross-Site Scripting (XSS) vulnerability exists in the chat functionality of the mintplex-labs/anything-llm repository, allowing attackers to execute arbitrary JavaScript in the context of a user's session. By manipulating the ChatBot responses, an attacker can inject malicious scripts to perform actions on behalf of the user, such as creating a new admin account or changing the user's password, leading to a complete takeover of the AnythingLLM application. The vulnerability stems from the improper sanitization of user and ChatBot input, specifically through the use of `dangerouslySetInnerHTML`. Successful exploitation requires convincing an admin to add a malicious LocalAI ChatBot to their AnythingLLM instance.

In mintplex-labs/anything-llm, an improper input validation vulnerability allows attackers to escalate privileges by deactivating 'Multi-User Mode'. By sending a specially crafted curl request with the 'multi_user_mode' parameter set to false, an attacker can deactivate 'Multi-User Mode'. This action permits the creation of a new admin user without requiring a password, leading to unauthorized administrative access.

A vulnerability in mintplex-labs/anything-llm allows users with manager roles to escalate their privileges to admin roles through a mass assignment issue. The '/admin/system-preferences' API endpoint improperly authorizes manager-level users to modify the 'multi_user_mode' system variable, enabling them to access the '/api/system/enable-multi-user' endpoint and create a new admin user. This issue results from the endpoint accepting a full JSON object in the request body without proper validation of modifiable fields, leading to unauthorized modification of system settings and subsequent privilege escalation.

mintplex-labs/anything-llm is vulnerable to path traversal attacks due to insufficient validation of user-supplied input in the logo filename functionality. Attackers can exploit this vulnerability by manipulating the logo filename to reference files outside of the restricted directory. This can lead to unauthorized reading or deletion of files by utilizing the `/api/system/upload-logo` and `/api/system/logo` endpoints. The issue stems from the lack of filtering or validation on the logo filename, allowing attackers to target sensitive files such as the application's database.

As a default user on a multi-user instance of AnythingLLM, you could execute a call to the `/export-data` endpoint of the system and then unzip and read that export that would enable you do exfiltrate data of the system at that save state.
This would require the attacked to be granted explicit access to the system, but they can do this at any role. Additionally, post-download, the data is deleted so no evidence would exist that the exfiltration occured.

If an attacked was given access to an instance with the admin or manager role there is no backend authentication that would prevent the attacked from creating a new user with an `admin` role and then be able to use this new account to have elevated privileges on the instance

A user who is privileged already `manager` or `admin` can set their profile picture via the frontend API using a relative filepath to then user the PFP GET API to download any valid files.
The attacker would have to have been granted privileged permissions to the system before executing this attack.

Any user can delete an arbitrary folder (recursively) on a remote server due to bad input sanitization leading to path traversal. The attacker would need access to the server at some privilege level since this endpoint is protected and requires authorization.

Enable exports of the database and associated exported information of the system via the default user role. The attacked would have to have been granted access to the system prior to the attack.
It is worth noting that the deterministic nature of the export name is lower risk as the UI for exporting would start the download at the same time, which once downloaded - deletes the export from the system.
The endpoint for exporting should simply be patched to a higher privilege level.
