CVE-2017-12373

A vulnerability in the TLS protocol implementation of legacy Cisco ASA 5500 Series ASA 5505, 5510, 5520, 5540, and 5550 devices could allow an unauthenticated, remote attacker to access sensitive information, aka a Return of Bleichenbacher's Oracle Threat ROBOT attack. An attacker could iterative...

Attack of the Killer ROBOT

On Dec 12th, 2017, researchers Hanno Böck, Juraj Somorovsky and Craig Young published a paper detailing an attack they called the Return Of Bleichenbacher's Oracle Threat ROBOT. This attack, as the name implies, is an extension of an attack published in 1998 that affects systems using certain...

19-Year-Old TLS Vulnerability Weakens Website Crypto

A vulnerability called ROBOT, first identified in 1998, has resurfaced. Impacted are leading websites ranging from Facebook to Paypal, which are vulnerable to attackers that could decrypt encrypted data and sign communications using the sites’ own private encryption key. The vulnerability is foun...

ROBOT Attack

BouncyCastle is vulnerable to the ROBOT attack. An attacker can leverage a variation of the Bleichenbacher chosen-cipher text attack to break confidentiality of TLS when used with RSA...
