Summary
A vulnerability has been discovered in Agnai that permits attackers to read arbitrary JSON files at attacker-chosen locations on the server. This issue can lead to unauthorized access to sensitive information and exposure of confidential configuration files.
This only affects installations with JSON_STORAGE enabled which is intended to local/self-hosting only.
Details & PoC
This is a path traversal vulnerability. An attacker can exploit this vulnerability by sending a specially crafted request:
GET /api/json/messages/%2e%2e%2f%2e%2e%2f%2e%2e%2f%2e%2e%2f%61%70%70%2fpackage HTTP/1.1
In this example, the attacker retrieves the package.json file content from the server by manipulating the file path.
The request is processed by the loadMessages handler in agnai/srv/api/json/index.ts and a file is read and returned to the client. The read filename is constructed using string interpolation, with no guard or check for path traversal: https://github.com/agnaistic/agnai/blob/2b878b7ca66471c5dd080197ad9ca2f7f0022655/srv/api/json/index.ts#L77
Constraints
Environment constraints: JSON Storage enabled (non standard)
Impact
This vulnerability is classified as a path traversal vulnerability. Specifically, any JSON file on the server which the webserver process has read privileges for, can be disclosed to the attacker.
