CVE-2017-17841

Palo Alto Networks PAN-OS 6.1, 7.1, and 8.0.x before 8.0.7, when an interface implements SSL decryption with RSA enabled or hosts a GlobalProtect portal or gateway, might allow remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, aka a ROBOT attack...

CVE-2017-17841

CVE-2017-17841 affects PAN-OS 6.1, 7.1, and 8.0.x before 8.0.7 where SSL Decryption with RSA or a GlobalProtect portal/gateway can leak TLS plaintext via a Bleichenbacher padding oracle (ROBOT). PAN-OS mitigations include upgrading to PAN-OS 7.1.15 or 8.0.7 (and later), or applying workarounds su...

BSA-2018-514

Security Advisory ID : BSA-2018-514 Component : TLS Implementations Revision : 1.1: Final TLS implementations may disclose side channel information via discrepancies between valid and invalid PKCS1 padding, and may therefore be vulnerable to Bleichenbacher-style attacks. An attacker could...

ROBOT attack against PAN-OS

ROBOT is an attack that affects the TLS RSA key exchange and could lead to decryption of captured sessions if the TLS server originally serving said captured session is still alive, vulnerable and using the same private key. PAN-89936 / CVE-2017-17841 While SSL Decryption and GlobalProtect are...

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...

CVE-2017-12373

CVE-2017-12373 is the BLEICHENBACHER-style RO[B]OT flaw impacting legacy Cisco ASA 5500 TLS stack (ASA 5505/5510/5520/5540/5550). An unauthenticated attacker can iteratively probe TLS handshakes to perform cryptanalytic operations that may decrypt previously captured TLS sessions. Cisco’s advisor...

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...
