CVE-2016-20104 Details
Description
EyeLock nano NXT 3.05.1193, 3.04.1108, 3.03.944, and 3.01.646 contain a path traversal vulnerability that allows unauthenticated attackers to read arbitrary files via the 'path' parameter. Attackers can send GET requests to /scripts/logdownload.php with traversal sequences like ../../etc/passwd, which readfile() returns unvalidated, disclosing local system files. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-19.
A path traversal vulnerability has been identified in EyeLock nano NXT versions 3.05.1193, 3.04.1108, 3.03.944, and 3.01.646. This vulnerability allows unauthenticated attackers to read arbitrary files by exploiting the 'path' parameter in GET requests sent to '/scripts/logdownload.php'. The vulnerability arises because the 'path' parameter is not properly validated before being used to read files, enabling attackers to access sensitive local system files such as '/etc/passwd'.
Users can upgrade to EyeLock NXT Firmware version 3.06.1260 to address this vulnerability.
