iniNet Solutions SpiderControl SCADA PC HMI Editor has a path traversal vulnerability. When the software loads a malicious ‘ems' project template file constructed by an attacker, it can write files to arbitrary directories. This can lead to overwriting system files, causing system paralysis, or writing to startup items, resulting in remote control.
Solution:
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.
