AI-analyzed exploit summary This repository provides a detailed guide for setting up HAProxy and Keepalived for high availability load balancing and failover. It includes configuration steps, SSL setup, and ACL-based routing examples.
Description
The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.

This repository provides a detailed guide for setting up HAProxy and Keepalived for high availability load balancing and failover. It includes configuration steps, SSL setup, and ACL-based routing examples.
This Metasploit module scans SSL/TLS services for supported versions and cipher suites, and checks for known vulnerabilities such as POODLE, DROWN, BEAST, and LOGJAM. It does not exploit these vulnerabilities but detects and reports them.
