CVE-2018-14942

Name of the Vulnerable Software and Affected Versions Harmonic NSG 9000 (affected versions not specified)

Description The issue allows remote authenticated users to conduct directory traversal attacks. This can be demonstrated by sending a POST request to the "/PY/EMULATION GET FILE" or "/PY/EMULATION EXPORT" API endpoints with the FileName variable set to a value like ../../../passwd in the POST data.

Recommendations For Harmonic NSG 9000, as a temporary workaround, consider restricting access to the /PY/EMULATION GET FILE and /PY/EMULATION EXPORT API endpoints until a patch is available. Avoid using the FileName variable in these endpoints with values that could facilitate directory traversal attacks. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
