CVE-2026-6620 Details
Description
A vulnerability was found in SonicCloudOrg sonic-server up to 2.0.0. The affected element is the function Upload of the file FileTool.java of the component File Upload Endpoint. The manipulation of the argument Type results in path traversal. The attack may be launched remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
A path traversal vulnerability has been identified in SonicCloudOrg sonic-server versions through 2.0.0. The issue arises in the file upload functionality, specifically within the 'Upload' method of 'FileTool.java'. The vulnerability allows authenticated attackers to manipulate the 'type' parameter, leading to unauthorized file writes in arbitrary directories on the server. This flaw could be exploited remotely, with a public exploit available.
It is recommended to implement strict validation on the 'type' parameter to ensure only allowed directory names are accepted. Additionally, paths should be normalized and validated to prevent traversal attacks.
