description
The issue affects the CGI service in GS1900-24E firmware through version 2.90(AAHK.2)C0. An unauthenticated attacker on an adjacent network may corrupt memory and potentially run operating-system commands through the device's HTTP management interface.
mitigation
Install GS1900-24E firmware version 2.90(AAHK.3)C0. Restrict HTTP management access to trusted administrative networks until model-specific firmware remediation is confirmed for other listed GS1900 devices.
