| Título | z-9527 admin ≤ commit 72aaf2d Path Traversal: '../filedir' |
|---|
| Descrição | An unrestricted file upload vulnerability exists in Z-9527 Admin ≤ commit 72aaf2d at the /upload endpoint, where the fileType query parameter is concatenated into the target filesystem path without validation or canonicalization, and the optional isImg check can be bypassed. As a result, authenticated attackers can write arbitrary files to the server filesystem. Mitigations include mapping fileType to a server-side whitelist of directories, canonicalizing and verifying that resolved paths are inside a fixed upload root, rejecting directory-traversal or absolute-path inputs, generating safe server-side filenames, validating content by magic bytes and size, storing uploads outside the webroot, and running the service with least privilege. |
