Detailsinfo

A vulnerability, which was classified as problematic, has been found in ArcadeData ArcadeDB up to 26.8.0. Affected by this issue is an unknown code of the file /api/v1/server. The manipulation with an unknown input leads to a path traversal vulnerability. Using CWE to declare the problem leads to CWE-23. The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. Impacted is integrity, and availability. CVE summarizes:

ArcadeDB versions before 26.8.1 fail to sanitize database names in the POST /api/v1/server endpoint's create database and drop database commands, allowing authenticated root users to write and delete arbitrary files outside the configured database directory. Attackers can supply database names containing ../ sequences to create databases at arbitrary filesystem paths or recursively delete directories the server process can access.
