Vulnerability from fkie_nvd - Published: 2025-07-16 21:15 - Updated: 2025-07-17 21:15
Severity ?
8.7 (High) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N
Summary
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.

La aplicaci\u00f3n no valida la entrada serializada en el endpoint de la copia de seguridad del administrador (`index.php/admin/update/sa/backup`), lo que permite a los atacantes especificar rutas de archivo arbitrarias mediante un payload `datasupdateinfo` manipulado. Los archivos se empaquetan en un archivo ZIP y se pueden descargar sin autenticaci\u00f3n. Esta vulnerabilidad puede explotarse para leer archivos arbitrarios en el sistema host, incluyendo archivos confidenciales del sistema operativo y de configuraci\u00f3n."
