The U.S. Cybersecurity and Infrastructure Security Agency (CISA) is warning of hackers actively exploiting flaws in Ubiquity UniFi OS and Lantronix serial-to-ethernet servers.

Ende Mai wurden kritische Sicherheitslücken in Ubiquiti UniFi OS bekannt. Inzwischen haben Angreifer diese im Visier.

Threat actors are exploiting CVE-2026-34908, CVE-2026-34909, and CVE-2026-34910, critical vulnerabilities in Ubiquiti devices.
