Sensitive update-data interception via unencrypted transport
Published Aug 17, 2023 · Updated Oct 1, 2024
Plaintext exposure in Genians Genian NAC and Genian ZTNA allows remote authenticated users to intercept sensitive update traffic. The update-server communication path transmits sensitive data without encryption, but Genians has not disclosed the protocol, field, or code locus. Exploitation requires adjacent-network access, low privileges, and user interaction, and the documented impact is disclosure rather than alteration or outage.
