A 19-year-old vulnerability has been re-discovered in the RSA implementation from at least 8 different vendors—including F5, Citrix, and Cisco—that can give man-in-the-middle attackers access to encrypted messages.
In 1998 the cryptographer Daniel Bleichenbacher discovered a severe attack against the use of RSA in the PKCS #1 v1.5 padding mode in TLS. Over the years researchers have found many variations and improvements of this attack, most notably the DROWN attack against SSL version 2.
But the threat from Bleichenbacher's attack isn't over yet. The newly found ROBOT attack is the rebirth of this old attack. It affects implementations from several different vendors and only involves slight variations of Bleichenbacher's original attack. Among the affected sites were Facebook and PayPal.
