Description
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.
