In Anti-Web through 3.8.7, as used on NetBiter FGW200 devices through 3.21.2, WS100 devices through 3.30.5, EC150 devices through 1.40.0, WS200 devices through 3.30.4, EC250 devices through 1.40.0, and other products, an LFI vulnerability allows a remote attacker to read or modify files through a path traversal technique, as demonstrated by reading the password file, or using the template parameter to cgi-bin/write.cgi to write to an arbitrary file.
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.
