Detailsinfo

A vulnerability was found in EyeLock nano NXT 3.01.646/3.03.944/3.04.1108/3.05.1193. It has been declared as problematic. Affected by this vulnerability is the function readfile of the file /scripts/logdownload.php. The manipulation of the argument path with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect confidentiality. The summary by CVE is:

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.

The advisory is shared at zeroscience.mk. This vulnerability is known as CVE-2016-20104 since 10/14/2026. The exploitation appears to be easy. The attack can be launched remotely.
