Detailsinfo

A vulnerability was found in IDS RTU 850C (unknown version). It has been classified as problematic. This affects an unknown code block of the component NC854/NC856 Modules. The manipulation with an unknown input leads to a path traversal vulnerability (File). CWE is classifying the issue as 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. This is going to have an impact on confidentiality. The summary by CVE is:

Directory traversal vulnerability in the NC854 and NC856 modules for IDS RTU 850C devices allows remote authenticated users to read arbitrary files via unspecified vectors involving an internal web server, as demonstrated by reading a TELNET credentials file.

The weakness was presented 05/31/2015 by Basti (Website). The advisory is shared at ics-cert.us-cert.gov. This vulnerability is uniquely identified as CVE-2015-3939 since 05/12/2015. It is possible to initiate the attack remotely. The requirement for exploitation is a authentication. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1006 for this issue.
