It is one of the most common scenario where you sitting behind corporate firewall.Īll the traffic is intercepted by corporate firewall and it replaces the certificate and then adds their own self signed certificate. Scenario 1 : Git clone - SSL certificate problem: self signed certificate in certificate chain Scenario 6 - POSTMAN - Postman error: self signed certificate in certificate chain | Unable to get local issuer certificate error.Scenario 5 - PHP - SSL certificate: unable to get local issuer certificate.Scenario 4 - pip install - pip install connection error: certificate verify failed.Scenario 3 - Node.js - npm ERR! Error: SSL Error: SELF_SIGNED_CERT_IN_CHAIN.Scenario 2 - Vagrant Up - SSL certificate problem: self signed certificate in certificate chain.

Scenario 1 - Git Clone - Unable to clone remote repository: SSL certificate problem: self signed certificate in certificate chain.

Ensure that private keys are not used anywhere with server software that supports SSLv2 connections.You can end with SSL certificate problem: self signed certificate in certificate chain in multiple cases but with my experience these are the most common scenario (Click on individual scenarios for more details). Solution Disable SSLv2 and export grade cryptography cipher suites. A man-in-the-middle attacker can exploit this to decrypt the TLS connection by utilizing previously captured traffic and weak cryptography along with a series of specially crafted connections to an SSLv2 server that uses the same private key. This vulnerability exists due to a flaw in the Secure Sockets Layer Version 2 (SSLv2) implementation, and it allows captured TLS traffic to be decrypted. Description The remote host supports SSLv2 and therefore may be affected by a vulnerability that allows a cross-protocol Bleichenbacher padding oracle attack known as DROWN (Decrypting RSA with Obsolete and Weakened eNcryption). Synopsis The remote host may be affected by a vulnerability that allows a remote attacker to potentially decrypt captured TLS traffic.
