What is CVE-2025-34076?

An authenticated local file inclusion vulnerability exists in Microweber CMS versions 1.2.11 and earlier due to improper handling of the backup management API. Authenticated users can exploit this flaw via the /api/BackupV2/upload and /api/BackupV2/download endpoints, which allow them to read arbitrary files from the system's filesystem. By manipulating the src parameter of the upload request, attackers may relocate or delete files based on the privileges of the web service user. The download endpoint can then be exploited to extract file contents, which results from inadequate validation of user-supplied paths and insufficient access restrictions related to file management.

Affected Version(s)

CMS 0 <= 1.2.11
