CVE-2025-34120

LimeSurvey 2.0+ - 2.06+ Unauthenticated Arbitrary File Download via Serialized Backup Payload PUBLISHED

Description (CNA)

An unauthenticated file download vulnerability exists in LimeSurvey versions from 2.0+ up to and including 2.06+ Build 151014. The application fails to validate serialized input to the admin backup endpoint (`index.php/admin/update/sa/backup`), allowing attackers to specify arbitrary file paths using a crafted `datasupdateinfo` payload. The files are packaged in a ZIP archive and made available for download without authentication. This vulnerability can be exploited to read arbitrary files on the host system, including sensitive OS and configuration files.
