CyberRota Analysis

AI-Generated

The vulnerability allows unauthenticated remote attackers to exploit the chat API by manipulating the conversation_id parameter, leading to arbitrary file writes and unauthorized reads from the server's filesystem. This could result in the exposure of sensitive data and potential server compromise. Organizations using Vanna versions up to 2.0.2 should prioritize patching this vulnerability to mitigate the risk of data breaches and unauthorized access.

Original NVD Description

Vanna through 2.0.2 contains a path traversal vulnerability in the FileSystemConversationStore persistence integration that allows unauthenticated remote attackers to write attacker-controlled JSON files to arbitrary filesystem locations and read conversation metadata from outside the intended store base directory. Attackers can supply path traversal sequences in the conversation_id parameter submitted to the unauthenticated chat API endpoints to escape the base directory during both write and read operations, enabling arbitrary file write with attacker-controlled content and unauthorized file read on the server filesystem.
