Technical details
A relative path traversal vulnerability (CWE-23) exists in the file upload functionality of MicroRealEstate through version 1.0.0-alpha3. The application uses parameters passed directly in a URL to determine the destination file path when writing uploaded files to disk. A remote attacker with low privileges can manipulate these parameters to traverse directories and write files to unauthorized locations. This can result in the overwriting of critical system files, leading to a denial of service or platform corruption. As of the advisory date, no fixed version has been identified.
