CVE-2026-27519
Binardat 10G08-0800GSM Network Switch Hard-coded RC4 Encryption Key
Description
Binardat 10G08-0800GSM network switch firmware version V300SP10260209 and prior use RC4 with a hard-coded key embedded in client-side JavaScript. Because the key is static and exposed, an attacker can decrypt protected values and defeat confidentiality protections.
