CVE-2017-1000385
The Erlang otp TLS server answers with different TLS alerts to different error types in the RSA PKCS 1 1.5 padding. This allows an attacker to decrypt content or sign messages with the server's private key this is a variation of the Bleichenbacher attack...
Bleichenbacher Attack on TLS Affecting Cisco Products: December 2017
On December 12, 2017, a research paper with the title Return of Bleichenbacher's Oracle Threat was made publicly available. This paper describes how some Transport Layer Security TLS stacks are vulnerable to variations of the classic Bleichenbacher attack on RSA key exchange. Multiple...
ROBOT Attack: 19-Year-Old Bleichenbacher Attack On Encrypted Web Reintroduced
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. Dubbed ROBOT Return of Bleichenbacher's Oracle Attack, the attack allows an attack...
TLS implementations may disclose side channel information via discrepancies between valid and invalid PKCS#1 padding
Overview TLS implementations may disclose side channel information via discrepancies between valid and invalid PKCS1 padding, and may therefore be vulnerable to Bleichenbacher-style attacks. This attack is known as a "ROBOT attack". Description CWE-203: Information Exposure Through Discrepancy...
