The following link provide more information about this vulnerability: SSL 3. “For each long-term support version, Google will offer free stability fixes and security patches for three years, with additional options for extended support. We found that 86% of the servers that support TLS include Triple-DES as one of the supported ciphers. IIS Crypto is a free tool that gives administrators the ability to enable or disable protocols, ciphers, hashes and key exchange algorithms on Windows Server 2008, 2012, 2016 and 2019. Nessus regards medium strength as any encryption that uses key lengths at least 56 bits and less than 112 bits, or else that uses the 3DES encryption suite. 0 and TLS 1. They also note/admit that it is easier to make such an attack if the attacker is on the same network. 0 release, which we expect to release tomorrow, we will treat triple-DES just like we are treating RC4. Not just HTTPS but you can test SSL strength for SMTP, SIP, POP3, and FTPS. The column was thought to be a place where members could ask questions for things that are outside the topic of the WUN Listserver, such as MilSat's, computer noise, general antenna questions, general radio questions, etc. 42873 - SSL Medium Strength Cipher Suites Supported;.

This required that university networking group scan the new webserver with a tool called Nessus. 24017 rather than 0. Share what you know and build a reputation. We have configured SSL in Apache Tomcat 6. (APPLIANCE-2015). Cause The 3DES algorithm, as used in the TLS and IPsec protocols, has a relatively small block size, which makes it easier for an attacker to guess repeated parts of encrypted messages (for example, session cookies). It also lets you reorder SSL/TLS cipher suites offered by IIS, change advanced settings, implement Best Practices with a single click, create custom templates. Note: the default SSL Profile affects all SSL Virtual Servers unless you create additional SSL Profiles and bind the additional SSL Profiles to individual SSL Virtual.

The configuration of this services should be changed so that it does not support the listed weak ciphers anymore. Get a review of concepts in an easy to read, bulleted form. Even if newer versions of TLS are also supported by the server, older client software might establish SSL 3. Numbers with this prefix were first introduced in 2002. If you have access to Oracle support, I suggest you review notes 2220788. Unfortunately this turned up several errors, all of them had to do with Secure Sockets Layer or SSL which in Microsoft Windows Server 2003 / Internet Information Server 6 out of the box support both unsecure protocols and cipher suites. 2 protocol with Forward secrecy. Below is a list of recommendations for a secure SSL/TLS implementation. Can someone help me patch this vulnerability? The description of the vulnerability can be found below: SSL Medium Strength Cipher Suites Supported Description: The remote host supports the use of SSL ciphers that offer medium strength encryption. That means that Linux in principle can be more completely and more deeply hardened then Windows, because it is more open system. In this manner, any server or client that is talking to a client or server that must use RC4 can prevent a connection from occurring. [*] Time: 2012-04-15 23:56:05 UTC Vuln: host=80. Very Strange Results from Scanner. Many common TLS misconfigurations are caused by choosing the wrong cipher suites. 1x EAPOL and older versions of Microsoft SQL Server to work. Remote Desktop can be secured using SSL/TLS in Windows Vista, Windows 7, and Windows Server 2003/2008. 18 Builds that are not configured with "enable-weak-ssl-ciphers both support SSLv2 and enable export cipher suites by can judge speed vs strength. 0, and weak ciphers enabled by default. 0 94437 SSL 64-bit Block Size Cipher Suites Supported (SWEET32) MEDIO 4. ini, xrdp(8) configuration file. Compatibility with SSL 2. In cryptography, RC4 is one of the most used software-based stream ciphers in the world. Companies, names, and data used in examples herein are fictitious unless otherwise. 0 servers MUST send version 2. SSL/TLS is not in play here so I'm talking about RDP encryption. In 2015, you have to bump from effectively HIGH:!aNULL because modern browsers reject some of the ciphers included with HIGH. The currently recognised protocols are, from highest to lowest: TLS1. Description The remote host supports the use of SSL ciphers that offer weak encryption. c, the code for masking out disabled ciphers needs a 315 kludge to work properly if AES128 is available and AES256 isn't 316 (or if Camellia128 is available and Camellia256 isn't). Vulnerabilities in SSL Medium Strength Cipher Suites Supported is a Medium risk vulnerability that is also high frequency and high visibility. Symantec helps consumers and organizations secure and manage their information-driven world. Nessus reports a vulnerability because of 64-bit cipher suites and SSL Medium Strength Cipher Suites Supported (even though it shows up as strong). , RC4, MD5, and others - is NOT allowed.
