CVE-2026-27520

8.7 highEPSS 0.2%

High (8.7) in binardat 10g08-0800gsm firmware. EPSS 0.2% chance of exploitation in the next 30 days.

Binardat 10G08-0800GSM network switch firmware versions prior to V300SP10260209 store a user password in a client-side cookie as a Base64-encoded value accessible via the web interface. Because Base64 is reversible and provides no confidentiality, an attacker who can access the cookie value can recover the plaintext password.
