Unknown · Microweber · CVE-2020-28337
Name of the Vulnerable Software and Affected Versions:
Microweber versions 1.1.20 and earlier
Description:
A directory traversal issue in the Utils/Unzip module allows an authenticated attacker to gain remote code execution via the backup restore feature. To exploit this issue, an attacker must have administrative user credentials, upload a maliciously constructed ZIP file with relative paths (e.g., ../../), move this file into the backup directory, and execute a restore on this file.
Recommendations:
For Microweber versions 1.1.20 and earlier, update to a version later than 1.1.20 to resolve the issue. As a temporary workaround, consider restricting access to the backup restore feature and the Utils/Unzip module to minimize the risk of exploitation. Avoid using the backup restore feature with untrusted ZIP files until the issue is resolved.
