Detailsinfo

A vulnerability was found in o1lab xmysql (affected version unknown). It has been classified as problematic. Affected is the function path.join of the file lib/xapi.js of the component xapi. The manipulation of the argument name with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality. CVE summarizes:

A path traversal vulnerability in o1lab/xmysql (all versions) allows an unauthenticated remote attacker to read and download arbitrary files from the server. The lib/xapi.js file at lines 338 and 424 uses the user-controlled req.query.name parameter in path.join(cwd, name) without sanitization before passing it to res.download(), enabling directory traversal via ../ sequences to access sensitive system files.
