A path traversal vulnerability has been reported to affect several QNAP operating system versions. If exploited, the vulnerability could allow users to read the contents of unexpected files and expose sensitive data via a network.
We have already fixed the vulnerability in the following versions:
QTS 5.1.4.2596 build 20231128 and later
QTS 4.5.4.2627 build 20231225 and later
QuTS hero h5.1.3.2578 build 20231110 and later
QuTS hero h4.5.4.2626 build 20231225 and later
QuTScloud c5.1.5.2651 and later
Se ha informado que una vulnerabilidad de path traversal afecta a varias versiones del sistema operativo QNAP. Si se explota, la vulnerabilidad podría permitir a los usuarios leer el contenido de archivos inesperados y exponer datos confidenciales a través de una red. Ya hemos solucionado la vulnerabilidad en las siguientes versiones: QTS 5.1.4.2596 compilación 20231128 y posteriores QTS 4.5.4.2627 compilación 20231225 y posteriores QuTS hero h5.1.3.2578 compilación 20231110 y posteriores QuTS hero h4.5.4.2626 compilación 20231225 y posteriores QuTScloud c5.1.5.2651 y posteriores
This vulnerability allows remote attackers to execute arbitrary code on affected installations of QNAP TS-464 NAS devices. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the handling of the HLS_tmp parameter provided to the share.cgi endpoint. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to create or modify files in the context of admin.
