Problem. While running penetration testing scripts against Hipchat Server OVA, you may potentially run into this vulnerability. Cause. According to the Weak Diffie-Hellman and the Logjam Attack page:. The Logjam attack allows a man-in-the-middle attacker to downgrade vulnerable TLS connections to 512-bit export-grade cryptography. Breaking down the Logjam (vulnerability)May 22, 2015 · What is it. Disclosed on May 19, 2015, the Logjam vulnerability (CVE-2015-4000) is a flaw in common TLS implementations that can be used to intercept secure communications.This TLS protocol vulnerability would allow an active man-in-the-middle (MITM) attacker to silently downgrade a TLS session to export-level Diffie-Hellman keys.
Elliptic-Curve Diffie-Hellman (ECDH) key exchange avoids all known feasible cryptanalytic attacks, and modern web browsers now prefer ECDHE over the original, finite field, Diffie-Hellman. The discrete log algorithms we used to attack standard Diffie-Hellman groups do not gain as strong of an advantage from precomputation, and individual How do I protect Cerberus against the Logjam vulnerability?Researchers have recently uncovered several weaknesses in how Diffie-Hellman (DH) key exchange has been deployed. The Logjam vulnerability exploits these weaknesses to negotiate weak encryption when used with SSL that can be broken with common hardware available today.
May 26, 2015 · A new vulnerability known as Logjam which allows the exploitation of secure TLS connections has been uncovered and it affects most popular browsers. Heres how Weakdh describes it:The Logjam attack allows a man-in-the-middle attacker to downgrade vulnerable TLS connections to 512-bit export-grade cryptography. LogJam This New Encryption Glitch Puts Internet Users at May 20, 2015 · Logjam can be exploited on a subset of servers that support the widely used cryptographic algorithm called the "Diffie-Hellman key exchange," which allows protocols like HTTPS, SSH, SMTPS, IPsec to negotiate a secret key and create a secure connection.
Researchers have uncovered a gaping encryption flaw in the way some servers handle the Diffie-Hellman Key exchange, the LogJam vulnerability downgrades TLS, Trending List of Secure Dark Web Email Providers in 2021 LogJam:Researchers Identify Another Web Encryption May 20, 2015 · A new potentially high-impact vulnerability called LogJam has been revealed by researchers, which has similarities to the FREAK (CVE-2015-0204) vulnerability disclosed a few months ago, whereby a man-in-the-middle attack can be implemented to
The Logjam vulnerability allows a man-in-the-middle (MITM) attacker to downgrade vulnerable SSL/TLS connections to 512-bit export-grade cryptography. The attacker can then observe and modify any data passed over the secure connection. Logjam attacks the Diffie-Hellman key exchange and any server which supports DHE_EXPORT ciphers may be vulnerable. Logjam SSL/TLS Vulnerability Exposes Cryptographic WeaknessMay 20, 2015 · The Logjam flaw is due to a vulnerability in the TLS protocol and puts the widely deployed Diffie-Hellman key exchange at risk, exposing Web users and
May 20, 2015 · The Logjam flaw is due to a vulnerability in the TLS protocol and puts the widely deployed Diffie-Hellman key exchange at risk, exposing Web users and sites. Multiple Vulnerabilities in OpenSSL (June 2015) Affecting Jun 12, 2015 · On June 11, 2015, the OpenSSL Project released a security advisory detailing six distinct vulnerabilities, and another fix that provides hardening protections against exploits as described in the Logjam research.
May 20, 2015 · The vulnerability derives from an issue in the TLS protocol itself. The attack is reminiscent of the FREAK attack, but is due to a flaw in the TLS protocol rather than an implementation The Logjam Attack - ANOTHER Critical TLS Weakness - Sep 09, 2015 · The Logjam attack allows a man-in-the-middle attacker to downgrade vulnerable TLS connections to 512-bit export-grade cryptography. This allows the attacker to read and modify any data passed over the connection.
We have uncovered several weaknesses in how Diffie-Hellman key exchange has been deployed:Logjam attack against the TLS protocol. The Logjam attack allows a man-in-the-middle attacker to downgrade vulnerable TLS connections to 512-bit export-grade cryptography. This allows the attacker to read and modify any data passed over the connection.The Logjam (and Another) Vulnerability against Diffie May 21, 2015 · Logjam is a new attack against the Diffie-Hellman key-exchange protocol used in TLS.
