CVE-2017-16900

Local file disclosure via guessable user identifiers

Published Feb 27, 2020 · Updated Aug 5, 2024

Incorrect access control in Hunesion i-oneNet 3.0.6042.1200 allows local users to read other users' file-transfer records by brute force. An HTTP file-transfer log accepts guessed user identifier numbers and returns the associated transfer date, filename, and file contents without enforcing ownership. Access requires a local product user, and the disclosed data is limited to other users' transfer logs and transferred file contents.
