CVE-2026-88623 Details
Description
NUUO Network Video Recorder 2.0.0 is vulnerable to arbitrary file read. In up.php, the url parameter submitted by the user via POST is received, and fopen() is used to open the URL in binary read-only mode. The content is then written to the /tmp/ directory, with the filename derived from basename() of the URL. This operation requires no authentication.
A vulnerability allowing arbitrary file read has been identified in NUUO Network Video Recorder version 2.0.0. The issue arises in the 'up.php' file, where the 'url' parameter submitted via POST is processed using 'fopen()' to read the specified URL in binary mode. The downloaded content is then saved to the '/tmp/' directory, with the filename derived from the URL's basename. This vulnerability requires no authentication and can be exploited remotely, as the 'url' parameter supports the 'file://' scheme, allowing access to arbitrary local files on the device.
It is recommended to remove internet exposure or enforce strict access controls on the vulnerable endpoint. Additionally, users should upgrade to a patched or secure version of the firmware.
