Radware Alteon devices with a firmware version between 31.0.0.0-31.0.3.0 are vulnerable to an adaptive-chosen ciphertext attack ("Bleichenbacher attack"). This allows an attacker to decrypt observed traffic that has been encrypted with the RSA cipher and to perform other private key operations.

Radware devices use the same value for the first two GCM nonces, which allows remote attackers to obtain the authentication key and spoof data via a "forbidden attack," a similar issue to CVE-2016-0270. NOTE: this issue may be due to the use of a third-party Cavium product.

Nortel Alteon ACEdirector WebOS 9.0, with the Server Load Balancing (SLB) and Cookie-Based Persistence features enabled, allows remote attackers to determine the real IP address of a web server with a half-closed session, which causes ACEdirector to send packets from the server without changing the address to the virtual IP address.
