Zip slip in Microweber

  • Disclosed: 10.02.2022
  • Updated: 11.10.2026 10:22

A directory traversal issue in the Utils/Unzip module in Microweber through 1.1.20 allows an authenticated attacker to gain remote code execution via the backup restore feature. To exploit the vulnerability, an attacker must have the credentials of an administrative user, upload a maliciously constructed ZIP file with file paths including relative paths (i.e., ../../), move this file into the backup directory, and execute a restore on this file.
