SSL/TLS implementations accept export-grade RSA keys (FREAK attack)

Overview Some implementations of SSL/TLS accept export-grade 512-bit or smaller RSA keys even when not specifically requesting export grade ciphers. An attacker able to act as a Man-in-The-Middle MiTM could factor weak temporary RSA keys, obtain session keys, and decrypt SSL/TLS trafflc. This iss...

mono -- TLS bugs

The Mono project reports: Mono’s implementation of the SSL/TLS stack failed to check the order of the handshake messages. Which would allow various attacks on the protocol to succeed. Details of this vulnerability are discussed in SKIP-TLS post. Mono’s implementation of SSL/TLS also contained...

Microsoft: All Windows versions Vulnerable to FREAK Vulnerability

Recently discovered FREAK vulnerability that apparently went undetected for more than a decade is reportedly affecting all supported versions of Microsoft Windows, making the flaw more creepy than what we thought. FREAK vulnerability is a disastrous SSL/TLS flaw disclosed Monday that allows an...

Microsoft Schannel Vulnerable to FREAK

Microsoft today issued an advisory warning Windows users that Secure Channel, or Schannel, the Windows implementation of SSL/TLS, is vulnerable to the FREAK attack. Disclosed this week, FREAK CVE-2015-1637 is the latest big Internet bug. It affects a number of SSL clients, including OpenSSL, and...

Internet Bug Bounty: FREAK: Factoring RSA_EXPORT Keys to Impersonate TLS Servers

Many TLS servers, including those hosting sensitive websites such as www.nsa.gov and connect.facebook.net, support weak EXPORTRSA ciphersuites. By factoring their 512-bit ephemeral RSA keys, a network attacker is able to impersonate these websites to web browsers and more generally, to client...

Security Advisory 3046015 released

Today, we released Security Advisory 3046015 to provide guidance to customers in response to the SSL/TLS issue referred to by researchers as “FREAK” Factoring attack on RSA-EXPORT Keys. Our investigation continues and we’ll take the necessary steps to protect our customers. MSRC Team...

SSL/TLS Cryptographic Degradation Man-in-the-Middle Hijacking Vulnerability

SSL/TLS is a cryptographic application. SSL/TLS has a security vulnerability that can lead to an attack known as FREAK Factoring RSA Export Keys, which can be exploited by an attacker to reduce the level of encryption and decrypt communications through a man-in-the-middle attack...

MS KB3046015: Vulnerability in Schannel Could Allow Security Feature Bypass (FREAK)

The remote Windows host is affected by a security feature bypass vulnerability, known as FREAK Factoring attack on RSA-EXPORT Keys, due to the support of weak EXPORTRSA cipher suites with keys less than or equal to 512 bits. A man-in-the-middle attacker may be able to downgrade the SSL/TLS...

Google Chrome < 41.0.2272.76 Multiple Vulnerabilities

The version of Google Chrome installed on the remote macOS host is prior to 41.0.2272.76. It is, therefore, affected by multiple vulnerabilities as referenced in the 201503stable-channel-update advisory. - Multiple use-after-free vulnerabilities in core/html/HTMLInputElement.cpp in the DOM...

Check Point Response to CVE-2015-0204 - TLS FREAK Attack

Symptoms - On Tuesday, March 3, 2015, researchers disclosed a new SSL/TLS vulnerability - the FREAK attack. The vulnerability allows attackers to intercept HTTPS connections between vulnerable clients and vulnerable servers and force them to use the "export-grade" cryptography, which can then be...

SSL/TLS EXPORT_RSA <= 512-bit Cipher Suites Supported (FREAK)

The remote host supports EXPORTRSA cipher suites with keys less than or equal to 512 bits. An attacker can factor a 512-bit RSA modulus in a short amount of time. A man-in-the middle attacker may be able to downgrade the session to use EXPORTRSA cipher suites e.g. CVE-2015-0204. Thus, it is...
