CVSS v3

NVD

Description

ShellHub is a centralized SSH gateway. Prior to 0.24.2, the device list endpoint accepts user-controlled identifiers in the the name field of each filter property in the base64-encoded filter query parameter and the sort_by query parameter, which are then passed directly as BSON/SQL keys in the database layer without validation. Any authenticated user can craft payloads that cause the aggregation / query to fail and the API to return HTTP 500 with no body, with no rate limiting applied. This vulnerability is fixed in 0.24.2.
