Side-Channel PoC Attack Lifts Private RSA Keys from Mobile Phones

Researchers have developed a proof-of-concept side-channel attack that allows them to pull encryption keys from a single decryption for a modern version of OpenSSL. The attack impacts mobile devices — without physical access to the handsets. A group of researchers at Georgia Tech were able to...

Code injection

The IKEv1 implementation in Clavister cOS Core before 11.00.11, 11.20.xx before 11.20.06, and 12.00.xx before 12.00.09 allows remote attackers to decrypt RSA-encrypted nonces by leveraging a Bleichenbacher attack...

CVE-2018-8753

CVE-2018-8753 affects the IKEv1 implementation in Clavister cOS Core (versions before 11.00.11, 11.20.xx before 11.20.06, and 12.00.xx before 12.00.09). The root cause is a Bleichenbacher RSA padding oracle that allows remote attackers to decrypt RSA-encrypted nonces during IKEv1 authentication, ...

Design/Logic Flaw

A vulnerability in the implementation of RSA-encrypted nonces in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to obtain the encrypted nonces of an Internet Key Exchange Version 1 IKEv1 session. The vulnerability exists because the affected software...

CVE-2017-7526

libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion. The same attack is believed to work on RSA-2048 with moderately more computation. This...

CVE-2015-9138

In Android before 2018-04-05 or earlier security patch level on Qualcomm Snapdragon Automobile, Snapdragon Mobile, Snapdragon Wear, and Small Cell SoC FSM9055, IPQ4019, MDM9206, MDM9607, MDM9625, MDM9635M, MDM9640, MDM9645, MDM9650, MDM9655, MSM8909W, SD 210/SD 212/SD 205, SD 400, SD 410/12, SD...

CVE-2015-9138

CVE-2015-9138 affects Android devices with Qualcomm-based SoCs. The issue arises when performing RSA encryption: the ce_util_to_unsigned_bin function uses the input address (c) instead of the buffer size, which can cause a logic overrun and potentially a buffer overflow. The vulnerability is desc...

Encryption 101: ShiOne ransomware case study

In part one of this series, Encryption 101: a malware analyst's primer, we introduced some of the basic encryption concepts used in malware. If you haven't read it, we suggest going back for a review, as it's necessary in order to be able to fully follow part two, our case study. In this study, w...

erlang: TLS server vulnerable to Adaptive Chosen Ciphertext attack allowing plaintext recovery or MITM attack

An erlang TLS server configured with cipher suites using RSA key exchange, may be vulnerable to an Adaptive Chosen Ciphertext attack AKA Bleichenbacher attack against RSA. This may result in plain-text recovery of encrypted messages and/or a man-in-the-middle MiTM attack, despite the attacker not...

CVE-2017-17427

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...

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: 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...

Updated tor packages fix security vulnerability

When checking for replays in the INTRODUCE1 cell data for a legacy onion service, Tor didn't correctly detect replays in the RSA- encrypted part of the cell. It was previously checking for replays on the entire cell, but those can be circumvented due to the malleability of Tor's legacy hybrid...
